Preparation, recording, editing and export of a trip - step by step.

a) Basic Settings:

  1. First set the desired units for all relevant data such as distance, position and date (option button in the LD-Log title bar -> settings -> units).
  2. If you would like to use LD-Log in sailmode, activate it in the settings at the bottom -> sailing features -> sail mode.
  3. Exit the settings.
  4. Enter a title and description for your trip (press 'trip' tab -> title row of the trip / or here the option button -> edit trip-info).
    Afterwards, in the trip editing screen press 'OK'.
  5. Enter a title and description for your current route (press 'route' tab -> title row of the route / or here the option button -> edit route-info).
    Afterwards, in the route editing screen press 'OK'.

b) Logging:

Make sure that you are located outdoors, as GPS signals cannot be received in most indoor situations.

  1. Initialise the GPS (log menu button at the bottom -> initialize GPS).
    Depending on when you last used your GPS, the initialisation can take up to several minutes.
    On devices with Android 4.1 up, you can follow the initilisation progress in the corresponding notification (pull down the Android status bar)
    Make sure that the GPS initialisation has been successful (see notification in the LD-Log title bar).
    If your GPS could not be initialized after several attempts, read under recommendations -> GPS initialisation.
  2. Set a desired waypoint interval (log menu button at the bottom -> log settings -> waypoint interval), default: 3 minutes.
    Additionally for a first test you may set the minimal waypoint distance to 0 meter in order to also save waypoints, if you do not actually move. Do not forget to readjust this setting afterwards.
    For now ignore all other settings.
  3. Exit the log-settings.
  4. Start the logging function (log menu button at the bottom -> start logging).
    Record manual waypoints if required (log menu button at the bottom -> take single waypoint).
    Record event-waypoints if required for immediate entries or actions like taking photos (log menu button at the bottom -> event waypoint).
    Activate tracking mode if required (log menu button at the bottom -> tracking), if you also want to record your movements between waypoints.

LD-Log is now tracking your progress. You may switch your device into standby mode.
If waypoints are recorded irregularly or not at all in standby mode, LD-Log might be blocked by a special power saving function on your device - read more under Notes / FAQs -> LOGGING.

c) Viewing / Editing:

  1. Swap Views between trip- / routes- / route- and waypoints-displays by pressing the corresponding tabs or swiping the screen horizontally.
  2. Switch to map view by pressing the globe symbol in the trip- or route-displays, or by selecting 'view waypoint on map' from the context menu of a waypoint.
  3. Edit a waypoint by pressing it in the waypoints list, or by selecting 'edit waypoint' from the context menu of a waypoint. You may also touch a waypoint in map view and press 'edit' in the following info-dialog.
    Take your waypoint photos or import images for this waypoint here.
    Afterwards in the waypoint editing screen press 'OK'.
  4. If by now you have set up more than one route, you may load each of these by selecting the desired one from the routes-list.
  5. If you wish to use one or more destination points, read under Notes / FAQs -> Destination Points.
  6. If you are using the sail mode, read under Sail Mode.

d) Saving, Exporting and more

  1. Save a trip by selecting 'save trip' from the trip context menu (tab trip -> option button -> save trip).
  2. Load a trip by selecting 'load trip' from the trip context menu or by pressing the option button in the LD-Log title bar and in the following context menu selecting 'saved trips'.
    Afterwards, in the trip overview press on a trip or select 'load trip' from the corresponding context menu.
  3. Export trip / route / waypoints by means of the appropriate options in the corresponding context menus.

For further functions, read through the basic operation below or the Notes / FAQs under the corresponding topics.
Also pay attention to the recommendations.
If you are using the free version of LD-Log, read about the limitations in LD-Log FREE.

Logging


Why are waypoints logged irregularly or not at all, when my device is in standby mode?

Check the notification in the LD-Log title bar to ensure that missing waypoints are not just skipped: in this case logging works normally, but waypoints are not saved, because they are too close (see log-settings -> min waypoint distance).
If waypoints are instead shown to be missed, it is possibly the case that there is no sufficient GPS-signal or you set your GPS accuracy-setting too extreme in combination with a too low waypoint-timeout (see log-settings).
If though waypoints are regularly saved in active device mode, but keep failing in standby mode with the same log-settings, probably a special power saving function is active on your device that blocks the GPS receiver. Deactivate those power saving functions, or better: Add LD-Log as an exception, if there is such a possibility. For example this is, how you deactivate the 'power saver' mode in Android 5.0 up: System Settings -> Battery -> Options Button -> Battery saver -> switch off & set 'Turn on automatically' to 'Never'.
Should you receive a warning message about missed waypoints in standby mode, read under WARNING MESSAGES -> What does the warning message mean, that the logging function has been blocked in standby mode.

What would be a reasonable waypoint interval for my usage?

This is dependent on your overall journey duration, the number of routes, your travel speed, battery power and the expected total number of waypoints (see below).
For a multi-day sailing cruise an interval of 8-10 minutes should be sufficient, particularly when taking a manual waypoint when changing direction.
For a prolonged hike, an interval of 2-3 minutes should be sufficient.
If you walk or bike in a city or are travelling by bike or car for a trip lasting several hours, then you probably want to log with an interval of one minute or less (see below) or just activate tracking, see under TRACK.
The interval may be changed while logging.

Is it possible to log with intervals less than one minute?

Yes, if you enter zero as the waypoint interval, it will be set to the minimum of 30 seconds.
This is a special feature: In this case the timeout will be set to one minute, meaning that if there was no determination of the current position within 30 seconds, it will carry on until the timeout is reached. With this setting, it is important that GPS accuracy settings are not set too high in order to get a waypoint every half minute (missed half-minute-waypoints will not be reported).
This setting should not be used over long travel durations due to power usage and data volume (see below).
If you would like to record your positions in even shorter intervals, activate tracking, see under TRACK.

Is there a maximum number of waypoints?

Data volume has natural limits - your internal device memory. This is dependent on individual hardware and software settings.
Even though a single waypoint uses negligible storage space, it is recommended to always set your log setting to a reasonable setting for the given conditions.

Does the minimal waypoint distance also apply to manual waypoints?

No. Manual waypoints will not be skipped due to an insufficient distance from the previous waypoint.

What does waypoint-timeout in the advanced log settings mean?

The time after which the determination of the current waypoint position will be aborted - a setting to minimise power usage if there's no sufficient GPS signal available.
This value can never be higher than the set interval-time (with one exception - see below). It should be set higher with increased GPS accuracy settings.
The timeout for manual waypoints is always 2 minutes longer than the global value for the automatic log to ensure that manual waypoints have a smaller chance of being missed.

May I record waypoints depending on my speed when logging?

Yes. In the advanced log settings you will find the setting 'Waypoints by Distance'. Enter the desired distance in which waypoints should be recorded. The waypoint interval for the next waypoint will then always be recalculated depending on the average speed of the last three waypoint distances. This setting is intended to further reduce battery consumption as well as to avoid getting unnecessary waypoint information when moving at slower speeds, or having to adjust the waypoint interval manually every time in such situations.
This function is only useful for movements without sudden changes in speed and / or frequent changes in direction.
Important:
1) Set the waypoint interval to a generous value, since after this time a waypoint is being taken in any case - regardless of the desired distance! Example: On a hike you would like to record waypoints approximately every 200 meters. At an average speed of 4 kmh (2.5 mph) about every 3 minutes a waypoint will be taken. In this case set the waypoint interval to at least 5 minutes, so that even at slower speeds the app keeps logging by distance.
2) In order to allow LD-Log to calculate speed correctly, do not start logging with this function before you actually start moving continuously. Should there be no previous waypoints available by which the next waypoint interval can be calculated (new route), LD-Log will start recording the first four waypoints with an interval of 30 seconds in order to get the necessary speed data for the following interval calculations.

How does the log start scheduling work?

In the log settings, choose a future time for automatic log start. When you leave the log settings by pressing the 'back' button of your device, the log scheduling with the current settings will be started.
Please note that completely shutting down your device will erase scheduling information.

What are the advanced GPS accuracy settings good for?

In normal situations, the adjustment of these settings is unnecessary. The default accuracy radius setting will be sufficient.
Furthermore, adjusting these settings is not recommended in all cases where reduction of battery usage is important, as they can unnecessarily extend the duration of the GPS device's activity.
Access to these settings may, however, be useful in situations where you are not measurably moving and/or are dependent on a (very) precise determination of position.
Please note, that these settings do not invariably lead to better results, but do increase the likelihood of more precise positioning.
If you are experimenting with those settings make sure that you are increasing the waypoint timeout accordingly, particularly if you are using multiple fixes.
Extensive testing with these settings should be done before using them permanently.

What is the advanced option 'Waypoint Time Source' good for?

Here you can set, if the time for wayopints will come from the device or the GPS satellites.
The time of the GPS satellites might be more accurate, but most notably it is independent from the device.
You should not change this setting, when the active route is still being recorded, as future waypoint times might differ from the preceding.
In addition you should not set it to satellite time when using an external GPS device, as satellite times might not be forwarded reliably.
You are advised to do your own tests before using satellite time.

What is the advanced option 'Use Alarm Clock Function' good for?

In order for LD-Log to work as battery efficient as possible, it uses an Android service to schedule its logging background tasks. As unfortunately many apps are using this service unnecessarily in standby mode, especially since Android 5.0 limitations are being integrated into the system with the reasonable aim to improve battery usage. Most manufacturers develop their own implementations of various battery saving modes and some even to the radical extent, that they implement a fixed, non-configurable delay of scheduled background processes in standby mode, like with some Samsung devices with Android 5.0 up. LD-Log is then not able to record waypoints in the desired interval, if it is under a certain threshold.
If you receive a warning message that the log function has been blocked in standby mode (see WARNING MESSAGES -> What does the warning message mean, that the logging function has been blocked in standby mode?) or you generally are having problems with timely recording of waypoints in standby mode and you cannot find a configurable power savings mode on your device with which you may resolve this problem, then activate this setting. In this case the Android alarm clock function will be used to schedule waypoint recording, which should not be subject of above restrictions. Please note that while logging an alarm clock symbol will be displayed in the Android status bar, showing the 'alarm time' of the next wayopint recording.
If this setting does not solve recording problems in standby, then try the setting 'Use Samsung 5.0+ Fix' (see below).

What is the advanced option 'Use Samsung 5.0+ Fix' good for?

If you receive a warning message that the log function has been blocked in standby mode and you cannot find a configurable power savings mode on your device AND the advanced option 'Use Alarm Clock Function' (see above) does not help, try this setting. It specifically refers to restrictions in some versions of Samsung's Android Version 5.0 and above, but maybe useful on other devices too. Use this setting WITHOUT the alarm clock function first and only activate that one too, if the 'Samsung 5.0+ Fix' alone does not help. Should the combination of the two settings not solve recording problems in standby, then you should contact the manufacturer of your device.
Please note, that the setting 'Use Samsung 5.0+ Fix' consumes additional battery power, if the waypoint interval is set to less than 5 min.

What else can I try, if waypoint recording is being blocked in standby mode?

In case you are receiving a warning message that the log function has been blocked in standby mode (see WARNING MESSAGES), you should already have tried the following solutions in this order:
If the log function is still being blocked, add LD-Log to the 'ignore optimization' android app list (Android 6.0 and above). This setting is pretty much hidden depending on the device manufacturer. In the original Android it can be found under Settings / Battery / Options -> Battery optimization. Then under 'Not optimized' choose 'All apps' and in the following app list click on LD-Log and set it to 'Don't optimize'.
It is known, that e.g. in Emui (Huawei / Honor) with version 4.0.x (Android 6.0) and above this setting must be done in addition to setting LD-Log as 'protected app' in the battery manager. In Emui 4.0.x you'll find the Android app optimization setting under Settings / Apps / Advanced (bottom of app list) / Ignore optimizations. Here add LD-Log as described above.
Should the declaration of LD-Log as a 'not optimized app' even in combination with the in above list mentioned settings not solve your problems with waypoint recording in standby mode, please send an email (see contact info at the bottom of this page).

Can I use LD-Log together with an external GPS device (e.g. over Bluetooth)?

Yes, if you are able to connect your external GPS device with an app that delivers its ongoing GPS position to the system for general usage by means of a so called 'Mock-Provider' (e.g. 'Bluetooth GPS' by GG MobLab, also see next topic).
From Android 4.3 up, the initial waypoint description is followed by '(EXT)', indicating that its position did not come from the internal GPS device.

What is the advanced option 'Bluetooth GPS App Control' good for?

If you are using an external GPS device and are connecting it with the app 'Bluetooth GPS' by GG MobLab, you may reduce the battery usage of your device even more while logging:
This setting syncs the bluetooth connection of the Bluetooth GPS app with your external GPS device for each waypoint localisation and stops it again afterwards.
Please note that this setting is considered 'experimental', which means that you should test its functioning with your devices extensively before relying on it (if you don't get an external GPS signal, battery usage will rise with this setting).
If no position is being delivered by the 'Mock-Provider' of the Bluetooth Gps app, LD-Log will automatically stop it and switch to the internal GPS device.

Presets: Which log settings are stored?

All settings except the automatic log start and the advanced options.

Why is only the active (last) route being recorded, even if I selected a different one at log start?

The concept of trip logging in LD-Log provides that routes are always being recorded chronologically.
If you would like to collect your ways seperately, simply create several trips, each of which you then load and further log as appropriate.



Waypoints


How can I quickly add entries to the last waypoint?

Choose 'edit last waypoint' in the route context menu or press the top waypoint in the waypoint list.

What is the difference between standard waypoints and waypoints with activated travel-log / logbook entry (event-waypoints)?

Waypoints with activated entry are highlighted and displayed with additional information in the waypoint list as well as in map view.
All waypoints will be exported to GPX / KML / KMZ and the trip-report solely with position- and time-information, whereas waypoints with activated entry are additionally exported as dedicated waypoints containing the complete set of entered information.

How can I add an immediate event-waypoint (with or without entries / photos) without having to wait for a GPS-fix?

Press the button 'Event-Waypoint' to open the appropriate quick-menu. (In sailing-mode you'll have the option to instantly set the engine state.)
This will store a waypoint with the last known position, which will be updated once the current position is being fixed. If the fix fails, it will be updated with the next regular waypoint-position.

What are the waypoint templates good for?

See under Editing.

How can I change the timezone of waypoints?

From LD-Log 4.0 waypoints will be saved together with the timezone currently set on the device.
Under certain circumstances it might occur that you would like to change the timezone of waypoints retrospectively.
In order to change the timezone of waypoints, in the waypoint editing screen press the top row where the waypoint time is displayed. A dialog will open where you can choose the appropriate time zone.
IMPORTANT: The selected time zone will be set for this and all subsequent waypoints of the complete trip (former time zones will be overwritten)!
You should normally do this only on the first waypoint of the first route of your trip.
If your trip spans across multiple time zones and you have to change them, proceed as follows: First note all waypoints with timezone changes. Start at the very first waypoint of your complete trip and chronologically ascending change the following waypoints with timezone changes.

How can I send a waypoint position via SMS or Email?

From the context menu of the desired waypoint in the waypoint list, choose 'send waypoint position'.
An automatically generated Google Maps link will be sent.
Or export a waypoint as GPX / KML / KMZ and send the file via email (just follow the export dialogs).

How can I navigate to a waypoint position with Google Maps Navigation?

From the context menu of the desired waypoint in the waypoint list, choose 'navigate to waypoint'.
Google Maps Navigation will be opened with the selected waypoint position set as destination.

How can I set a waypoint position as destination point?

From the context menu of the desired waypoint in the waypoint list, choose 'set waypoint as destination'.
The waypoint position together with the entered title will be saved as a new destination.



Destination Points


Where do I find my trip destinations?

Open the destination list by pressing the flag symbol button in the button row at the bottom of the screen.
Or from the trip options choose 'Load Destination'.
All destinations are also being displayed in map view.

How can I create a new destination?


How can I import destinations from a KML file?

Press the options button in the title bar of the destination list -> Import Destinations from KML.

What to consider when importing destinations from KML?

LD-Log solely imports destinations from 'Point' coordinates (single placemarks) in a KML file.
Other forms of coordinates like 'Line Strings' (path marks) will be ignored.

How can I edit name and coordinates of a destination retrospectively?

Press the option button of the corresponding destination in the destination list and choose 'Edit Destination'.

How can I load a destination as the trip-destination (current destination)?

Simply press the destination in the destination list, or press its options button and choose 'Load Destination'.
In map view touch a destination point and in the following info dialog choose 'Load'.

How can I remove the current destination?

In the trip options -> Remove Destination
In the map options -> Remove Destination Point
the destination itself will not be deleted.

How can I finally delete a destination?

In the destination list: Options button of the corresponding destination -> Delete Destination.
In map view: Touch the destination point and in the following info dialog press 'delete'.

How can I finally delete all destinations?

Press the options button in the title bar of the destination list -> Delete all Destinations.



Track


What does the tracking function do?

With tracking enabled, additional GPS-coordinates (trackpoints) are stored between waypoints in very short intervals. This way the travelled path will be displayed and calculated more precisely, especially when you often changed direction. During tracking the GPS receiver is kept on continuously and therefore the power usage strongly increases!
You may switch tracking on and off while logging and as such only track certain parts of your way by the second, like the exact drive through the city after a longer drive on the highway which was logged by the minute.

How do I start track recording?

Activate the tracking button in the log menu and start logging.

What are the track settings good for?

Here you adjust, how accurate the track is being recorded. These settings have a direct impact on the data volume of the recorded track. But also the already strong battery usage during tracking will be reduced a little, when choosing longer trackpoint intervals. Therefore you should always choose reasonable values for those settings, depending on the type and duration of your locomotion.

For which situations is the tracking function suitable?

For all types of locomotion at which the minimum waypoint interval of 30 seconds still pictures a too rough path and which duration is not overly long, e.g. walks, jogging, car drives and motorcycle- / bicycle rides through the city or the open country, etc.

My device is always on charge, may I track infinitely?

No. Because data is being stored permanently, the available internal memory will be finally consumed at some point. Recording enduring journeys with the tracking function enabled can therefore not be recommended. Also take into account that when exporting large trip files, other software might have problems with them.
If you would like to do this nonetheless, you should then separate your journey into several trips, thus saving your current trip file and starting a new trip after a few days latest, depending on your average daily recording time. In your case you should also especially be aware of setting the trackpoint interval and minimum distance to as high as possible values (a for the desired accuracy only just acceptable amount).

Tracking is activated and logging started, but I don't see any progress displayed?

The data displayed in LD-Log is transmitted with each waypoint, which means that the update frequency is dependent on the waypoint interval.



Display


Why are some longer titles and descriptions truncated in the trip-/ route and waypoints-displays?

For lack of space. To view complete information go to the respective edit-screen.
The edit-fields of the descriptions will expand automatically with new lines, which means that there's no restriction on text length.
All information will be saved and exported at full length.

The displayed number of waypoints on the route-screen is followed by some letters and more numbers - what do they mean?

'sk': skipped waypoints (waypoint wasn't far enough from the previous one, see log-settings 'min waypoint distance')
'ms': missed waypoints (insufficient GPS signal and/or overly extreme accuracy settings in combination with the selected waypoint timeout)

The displayed GPS accuracy of the last waypoint on the route-screen is followed by some letters and more numbers - what do they mean?

Those appear when you are using the advanced GPS accuracy settings.
e.g. 'S 5/8': for the position-determination of the last waypoint 5 out of 8 available satellites have been used.
e.g. 'SNR 32': for the used number of satellites, an average signal-to-noise-ratio of 32 has been calculated.
If you've been setting multiple GPS-fixes, then all displayed accuracy numbers are averaged by the number of used GPS-fixes.

In the waypoint list I see entries that are colored green or orange - what do they mean?

Green indicates an event-waypoint for which a current position has not been obtained yet and therefore took over the position of the previous waypoint.
Orange indicates an event-waypoint for which a current position could not be obtained and therefore took over the position of the following waypoint.

Where can I set the default number of waypoints shown in the waypoints list?

In the waypoints display option menu (press the eye symbol in the title row of the waypoints screen)

How can I view added waypoint distances for a route in the data row of the waypoints list (output like in a logbook)?

By selecting to show only event waypoints (see next question).

How can I only display event-waypoints in the waypoints list?

In the waypoints display option menu (press the eye symbol in the title row of the waypoints screen)

How can I hide the descriptions for standard waypoints in the waypoints list?

In the waypoints display option menu (press the eye symbol in the title row of the waypoints screen)

How can I hide the data row in the waypoints list?

In the waypoints display option menu (press the eye symbol in the title row of the waypoints screen)

How can I hide the photos in the waypoints list?

In the waypoints display option menu (press the eye symbol in the title row of the waypoints screen)



Map View


How do I get to the map view?

Press the globe symbol in the trip- or route-screen, or by choosing the corresponding route- or waypoint-options ('View ... on Map').

What do the symbol buttons above mean?

From left to right:
1.) Live-position ON / OFF: Here you can let your current position be shown on the map. In order to save battery, the live position will be disabled as soon as the map view gets to the background or the screen is switched off.
2.) Info display ON / OFF: Last heading / speed, heading / distance to destination (if one is loaded), with live position additionally current heading / speed.
3.) New waypoint record / cancel: Only possible, if the active (latest) route or the whole trip is being displayed.
4.) Tracking mode ON / OFF: Only possible, if the active (latest) route or the whole trip is being displayed AND the automatic log is running.
5.) Go to last position: With live position on, go to current position, otherwise go to latest position of the route / trip.
6.) Keep screen on ON / OFF: When activated the screen will not automatically switch off as long as the mapview is kept in the foreground.
7.) View options
8.) Map options (below view options): Options depending on active map view (Standard / Google)

How can I refresh my current map view when automatic logging is active?

The map will automatically be refreshed as soon as a new waypoint has been recorded and the active (latest) route or the whole trip is being displayed.

Under which conditions does the map follow my position automatically?

As soon as the latest recorded position is centered in the map (arrow button 'go to last position'), the map will be recentered with each position update and as such the position being followed automatically. This applies to the last waypoint of the active route for each new waypoint as well as with the live position for position updates. The map will always be newly centered as soon as the live position has been found.

How can I get to the last waypoint of the route / trip when the live position is active?

Select 'go to route / trip end' the view options menu (top right).

How can I only display event-waypoints in the map view?

In the view options menu (top right).

How can I display thumbnails of my images instead of the camera symbol at all zoom levels in the map view?

In the view options menu (top right).
With the default setting image thumbnails are only shown at a close zoom level.

How can I save a screenshot of my current map view?

In the view options menu (top right).

Why is the distance number in the scale of the map view changing not only during zooming, but also when panning at smaller zoom levels?

Because the earth is a ball and not a rectangle.

How are maps in the standard map view being cached?

All previously viewed map tiles of the respective map source are automatically being cached and remain available for offline usage. It should be noted, that map tiles of the current view are only available for the corresponding current zoom level, which means that when zooming into the map, they have to be loaded again for the next zoom level. If you're offline and are zooming into an area that hasn't previously been viewed on this zoom level, then it is impossible to get a detailed map displayed. In this case you're getting a scaled version of the last maximum available zoom level.
Please note, that the storage space has its limits - depending on your available storage space it will be dynamically adjusted. As soon as its maximum size is reached, older tiles will automatically be deleted in the order of their expiration times.

How can I create custom maps and let them display in the standard map view?

LD-Log supports the offline map formats 'Osmdroid SQLite', 'Osmdroid Zip', 'MBTiles' and 'Osmdroid GEMF'. There are maps in those formats to be downloaded around the internet. With tools such as 'Mobile Atlas Creator' (MOBAC) you may also create custom maps from various sources in these formats. In conjunction with other software like QGIS e.g. you can even use self scanned maps with LD-Log. For creating custom maps that way, quite some level of knowledge and/or practice is needed. Please note that there is no support for creating maps or using third party software.
If you have the free choice of one of the supported map formats (like in MOBAC) generally 'Osmdroid SQLite' is to be preferred. Copy your offline map files to the LD-Log folder 'maps' (see below) and they will automatically be available with the next opening of the standard map view. Recognized offline maps may then be switched on and off separately in the map options. When activated, they will always be displayed on top of the base map with each of their containing zoom level.

Where is the storage for offline maps of the standard map view located?

With the first launch of the standard map view, a folder named 'maps' will be created within the LD-Log / LD-Log FREE main folder. Here you must copy your offline map files. In the automatically created subfolder 'cache', all already viewed online map tiles are being stored - this is being managed by the map view itself.

I have successfully integrated an offline map like described above, I'm also seeing it in the menu 'Offline maps' as being activated, but it isn't shown in the standard map view?

An offline map always only contains a certain area and this only for a certain number of zoom levels. Otherwise files would grow too large and could not be handled. The map will now only be displayed in the given area on exactly the zoom levels, that are actually available in the offline map. If you are positive that you are viewing a part of the containig area in one of the available zoom levels, but still can not see the map, is it possible that another offline map of this area is overlapping the current one? (see below 'In which order are map layers being displayed in the standard map view?').

In which order are map layers being displayed in the standard map view?

Available and active offline maps are displayed in alphabetic order on the top level of the map view. This means that if you would like to display different offline maps with overlapping map areas on the same zoom levels simultaniously, make sure that the filename of the map that should be displayed on top is listed before the one in the back (example: 'Brooklyn_1.mbtiles' will be displayed in front of 'Brooklyn_2.mbtiles').
As background map the selected online map (base map) respective its cached version will be displayed. If activated, the transparent OpenSeaMap layer (see below) will be shown on top of all other map layers.

What should I consider, when there are several offline map files simultaniously present int the 'maps' folder?

Always only activate those offline maps that you are actually currently using (see map setting 'Offline Maps' in the standard map view)! Otherwise with each zoom or moving action unnecessary map archives will be searched through, which causes quite some computation and thus battery usage.

Where can I read the currently active zoom level in the standard map view?

The number behind 'Zoom' at the bottom to the right in the map scale bar.

Why does the map in the standard map view get pixelated when I zoom in?

There are two special features of the standard map view that might produce a pixelated map display.
1.) Stepless Zoom: In the standard map view you may zoom in and out floatingly as opposed to the legacy Google map view. This means that the map is being scaled while zooming between the fixed zoom levels. Thus maps may appear pixelated at a point where you zoomed into the current zoom level so far that it is close to the next 'real' zoom level with more detailed map tiles.
2.) Map simulation: If there is no network available or you've activated the map view's offline mode, map tiles of unavailable zoom levels will be scaled from lower zoom levels, so that you're still able to use the map on those levels even though in a worse resolution. If there are only tiles available from a far lower zoom level than the current one, the map display may seem pixelated beyond recognition due to the extreme enlargement.

What is the map option 'Show OpenSeaMap' in the standard map view good for?

With this option the transparent OpenSeaMap layer will be displayed on top of all other maps (sea marks with a worldwide divergent coverage). In sail mode this option is initially activated by default. Deactivate this option if you are not absolutely needing it, e.g. if you're displaying an offline nautical chart which already includes sea marks on its own. The display of additional map layers always consumes additional battery recources.
Opposed to the base and offline maps, the OpenSeaMap layer will not be scaled, when there are is no data for the current zoom level available. This means that when being without an internet connection or in map offline mode, sea marks will be missing for areas and zoom levels that have not previously been viewed (cached).

How can I switch satellite view in the Google map on and off?

In the map options menu.

Why do I not see a map in Google map view when there is no internet connection?

Unfortunately the integrated Google map view only works online.



Compass


What does the compass need the current GPS position for?

The LD-Log compass is designed as a bearing compass, which points to true north (geographic north). The GPS coordinates are used in order to determine the local declination (angle between true north and magnetic north) and thus to be able to calculate the true north value from the magnetic sensor values. Furthermore the current GPS coordinates are needed for calculating direction and bearing to the destination point.

Why is the field with the current GPS position colored in red?

The last GPS position is out of date (older than 5 minutes). Data might be incorrect. Press on the red field to get this info and start the position update process if nessecary.

How can I update the GPS position or abort the position update process?

Press the update arrow, respectively the cross symbol on the right top of the compass rose.

Why should the compass be calibrated with every usage?

The compass display uses the accelerometer of your device in order to set the north value of the electromagnetic field sensor in the correct relation to the actual orientation of your device. In order for the accelerometer to deliver exact values of this orientation, it must have reached its minimum and maximum values for each axis of the three dimensional orientation space at least one time. This is being done by completely turning the device around each of its three axis. Even if you have used the compass not that long ago, it might happen that those values are not correct anymore when restarting the compass and that it will show a wrong direction, be it only by a few degrees. You may get an instruction on how to calibrate the compass correctly at any time by pressing the question mark in the right of the compass screen title bar.

Why is my LD-Log compass inaccurate although I've been calibrating it several times?

The compass sensor reacts very sensitive on any electromagnetic material (e.g. magnetic tablet covers!) as well as on electric currency. Therefore you will get best results when remote from such influences. Furthermore the accuracy of the compass is dependent on your individual device and may vary between devices even of the same model. As such it is strongly recommended, to compare the compass to a physical compass, before ultimately relying on it! If the compass is still too inaccurate to be useful even by taking into account the above points, then unfortunately this app cannot help it.



Editing


What are the templates good for?

The template functions in the trip- / route- and waypoint-editing may help you to save recurring entries and then quickly load them for new trips / routes / waypoints.
Waypoint templates are directly available to choose from for immediate event-waypoints (Log Menu -> Event-Waypoint -> From Template).
The template function has been developed with focus on the sail mode with its many logbook entries, but may be helpful for other use cases also.

Why must I choose, which information is being saved in a template?

Because all of these information will be overwritten, when loading the template. Sometimes maybe you would like to take over the waypoint name of a template (such as 'departure'), sometimes only the description. This option must be set already during saving the template in order to be able to load the template without another dialog.

When saving a waypoint template, could this include the actual coordinates or the time?

No.



Photos / Screenshots


How do I attach images to waypoints?

1.) Taking photos directly together with a new waypoint: Log Menu -> Event-Waypoint -> Photos
2.) Taking photos for an existing waypoint: Select the waypoint in the waypopint list or in map view and in the waypoint editing screen choose 'Take a Photo'
3.) Importing already available images for an existing waypoint: Select the waypoint in the waypopint list or in map view and in the waypoint editing screen choose 'Import an Image'

What is happening to my recorded or imported images?

Images that have been taken with the photo function in LD-Log are stored in the LD-Log folder 'photos' and in the subfolder with the trip-ID of your current trip (see above). With some versions of Android, this image as well as all dismissed photos are kept in the general image-folder of your camera app, so only the confirmed image will be copied. With other versions, only the confirmed image will be saved solely in the LD-Log photo folder.
Images that are being imported to LD-Log will be copied to the above mentioned folder, so they are kept in the original location.
Filenames of the images are generated from the corresponding route and waypoint numbers together with a timestamp indicating the moment of capturing / copying.
A thumbnail of each image is stored in the subfolder 'thumbs'.
Each image file is geotagged with the position of the corresponding waypoint (previously embedded geotags will be overwritten).

How can I have a larger view of my images in the waypoint editing screen?

Press the button '[+]' between 'take a photo' and 'import an image' once there are actual images available. If - due to enlargement - some images are no longer visible, scroll the image bar horizontally.

How can I view all of my trip images?

Press the images symbol button in the button row at the bottom of the screen or touch an image in the waypoint list / the waypoint editing / the waypoint details dialog in map view.

How can I send / remove / delete an image?

From the image context menu (press + hold the image on the waypoint editing screen or press the options button on the trip-images screen)

What is happening to my saved map-screenshots?

Map-screenshots are stored in the LD-Log folder 'screenshots'. You may reimport them into the appropriate waypoints, e.g. in order to integrate them into your HTML trip-report.

What are 'optimized' images?

When exporting files that should include images or sending an image, every time you may choose the 'optimized' option. In most cases you are much are advised do this, especially if the exported or further processed files (e.g. as PDF) should be sent or otherwise transferred over the internet.
Optimized images will be scaled down to reduced dimensions and are newly compressed. This way the optimized images often only have the fraction of the file size of the original ones while at the same time maintaining sufficient quality for most uses. Also portrait format images are being rotated by image calculation for correct display orientation in every export format.
Optimized images are stored separately in the subfolder 'optimized' of your trip images folder.



Export, etc.


Where are my exported / saved files located?

Depending on your device, either on the SD-Card or the internal storage in the folder 'LD-Log', respectively 'LD-Log_FREE' and its subfolders.
The respective folders will be created when you export or save a corresponding file for the first time.
Filenames are generated automatically from the respective given trip-, route- or waypoint-names.
Please note: files of the same name and type will be overwritten.

How can I get a detailed overview of all saved trips?

You can reach the overview from the menu button in the LD-Log title bar -> 'saved trips' or from the trip context menu -> load trip.

How can I print out my travel-log / logbook or export it to a PDF file?

First make a HTML trip report (trip context menu -> export trip). If your trip includes images, you are advised to use the options 'optimized' or 'thumbnails' instead of 'original'. This will reduce file sizes and ensure correct orientation of portrait format images. Afterwards choose to view the report.

How can I send my travel-log / logbook or open it in another viewer?

Make a trip report (see above), in the following dialog, press 'View' / 'Yes' and press the appropriate Buttons at the bottom of the report-view.

How can I export only event-waypoints to my trip-report?

The trip-report contains a detailed list of your event-waypoints followed by a potentially long list of all recorded waypoints for each route. If you would like to only export event-waypoints to your trip report, you may change this behaviour in the main settings under 'trip-report export settings -> waypoint data'.

How can I publish my HTML-Trip-Report online?

Copy the appropriate HTML file from the LD-Log folder 'report-files' to your FTP-Server.
If there are any embedded images, you'll also have to copy the image folder under 'photos' with the corresponding trip-id. Or create a zip file in the HTML-trip-report view of LD-Log, transfer it to your computer and extract it. Now all the files needed should be included in the correct folder structure. If you haven't exported your trip with the 'optimized' option, you should make your original images smaller before putting them online, however. In addition, the relative path to the images must correspond to the path structure inside the LD-Log folder on your device. Thus the images relative to the HTML document must be located in a path structure such as '../photos/trip_[TRIP-ID]/'.

How can I get a summary table overview of my travel-log / logbook?

Make a trip report (trip context menu) and choose 'CSV files' in the following dialog. A comma-separated file for each dataset (trip, routes and waypoints) will be created. Those files are located in the LD-Log folder 'report-files' and in the corresponding CSV subfolder of your trip.
In the LD-Log main settings, you may choose if all waypoints or just the event-waypoints are to be exported ('trip-report export settings -> waypoint data csv').
When opening the files in spread sheet software or other CSV viewers, pay attention to the correct settings:
Character Set = UTF-8 / Field delimiter character = comma (,) / Text delimiter and recognition character = double quotes (") / First line = Header

How can I send my GPX- / KML- / KMZ-files or open them in a viewer?

Make a GPX- / KML- / KMZ-file by choosing 'Export...' from the corresponding context menus and press the appropriate buttons in the following dialogs.

What are the GPX-export settings good for?

GPX-Viewers generally display imported files quite differently and often do not display the complete embedded information.
Using the export settings you'll have the option to adjust the GPX-display for your preferred viewer according to your needs.
Choose how route-paths are to be exported (as GPX routes, GPX tracks or GPX track segments).
Additionally you may embed all information displayed or calculated within LD-Log into waypoints:
Trip- and route-names as well as their corresponding descriptions will be exported to their respective first waypoint, while their data will be saved to their respective last waypoint.
Since there is no consistent new-line attribute for the GPX format, LD-Log uses different characters for structuring the exported information.

What are the KML- / KMZ-export settings good for?

If you do not view your KML / KMZ files in Google Earth desktop versions, you probably will not have access to the complete exported trip- or route-data, as they are only accessible by clicking them in the list view.
In order to view this data in other viewers like the mobile versions of Google Earth, you have the option to include them into waypoint infos:
In the export settings you may choose to export trip- and/or route-data to the waypoint-infos. These will be saved to the last waypoint of the corresponding route / the last waypoint of the trip.

What is the difference between KML and KMZ?

KMZ essentially is a Zip file, which contains a KML file as well as possibly other folders and files. This way it is possible to embed images directly into the file.
For LD-Log this means:

How can I completely import my KML- or KMZ-file in Google MyMaps and other limited software?

The standard export of KML and KMZ is optimized for the desktop version of Google Earth. The files contain many layers which present a most clear view and which can be separately hidden or shown. This complexity however is too much for Google MyMaps and possibly some other software, or rather is MyMaps limited that way that it only accepts a small number of layers for import. Furthermore there are some basic display issues with Google MyMaps. That's why an option 'Optimized for Google MyMaps' was included in the export options (Export -> KML or KMZ -> Optimized for Google MyMaps). With this option the export data is being organized in a different way so that Google MyMaps and other limited software should be able to import them without problems.

Why are the export-data or trip-report incomplete after being sent or opened?

You are possibly sending or opening an old file:
If the file already exists in the export dialog, first press 'New' to create a fresh file from the latest data, otherwise you are opening the previously created file.
Afterwards, you may send or open the new file directly.

Where do I find the trip-ID of my trip?

In the trip editing screen (press screen trip) on the top right.
The trip-ID is generated from the timestamp created when the trip, respectively it's first waypoint was recorded.

How can I send trip files ('ldlog' files), e.g. in order to transfer a backup of my trip?

In the menu of the tab 'trip' choose 'Send Trip File'.
If you would like to send another than the current trip, open the trips overview (press the menu button in the LD-Log title bar and choose 'saved trips' or press 'load trip' in the trip context menu) and in the context menu of the corresponding trip, choose 'send trip file'.

How can I transfer (import) trip files ('ldlog' files) from external sources to my local trips folder?

Open the trips overview (press the menu button in the LD-Log title bar -> 'saved trips' or press 'load trip' in the trip context menu), then press the options button in the title bar and choose 'Import Trip File'.

HELP - Why are my LD-Log files all of a sudden missing?

There have been a couple of reports by users of the full version of LD-Log, whose files from the LD-Log folder suddenly disappeared. The source of this problem has been tracked down to the app 'Clean Master', but might also apply to other 'cleaning' apps.
The problem can ONLY occur, if you can confirm ALL of the following:
The problem here is, that once you export a file from LD-Log FREE, 'Clean Master' records, that the main folder 'LD-Log' on your storage has been created by LD-Log FREE. Now if you installed the full version of LD-Log (which - before LD-Log FREE V3.1 - used the same folder name) later and afterwards uninstalled LD-Log FREE, the folder 'LD-Log' is now considered junk by 'Clean Master' (because the app LD-Log FREE, which originally created this folder is no longer installed). The LD-Log folder is now being recommended to be deleted or even being deleted automatically by 'Clean Master' depending on your settings. Even if the folder is being recreated by the full version of LD-Log, 'Clean Master' still considers the folder 'LD-Log' belonging to former LD-Log FREE and keeps on deleting it!
To get rid of this problem or prevent from it you can do ONE of the following:



Sail Mode


What is the sail mode good for?

The sail mode offers an intuitive way to keep a complete nautical ship's log. When activated, all respective logbook entries are available in the trip-, route-, and waypoint-editing for direct input or as predefined selection. Furthermore in the trip- route- and waypoint-display additional relevant data like distance under sail / engine, logbook entries and others will be shown.

How do I activate the sail mode?

In the main settings (option button in the LD-Log title bar -> settings) at the bottom. If you do not want to solely use LD-Log in sail mode, you may set the sail mode per trip instead: trip options -> edit trip info -> trip settings.

How can I set additional sails to select from in the waypoint logbook entries?

If you are using more or other sails than the preset fore and main sails (e.g. on a ketch, a traditional sailer, etc.), you may add them in the sail mode settings (located in the main settings at the bottom). Enter the sail names comma separated into the corresponding dialog (custom fore sails / custom mainsails), e.g. 'Inner Jib, Outer Jib' as fore sails and 'Mizzen, Mizzen Reef 1, Mizzen Reef 2' as mainsails. They will then be available in the waypoint logbook entries for selection under 'custom fore sails' and 'custom mainsails'.

Where can I change the units for wind strength and temperature that are used in the waypoint logbook entries?

In the sail mode settings (located in the main settings at the bottom).

Where can I set the type of foresail (single sails / rolling genua / rolling jib) that is used in the waypoint logbook entries?

In the sail mode settings (located in the main settings at the bottom).

How can I create custom templates for my trip, route or waypoint logbook entries?

For some recurring logbook entries it might be useful to create custom templates for quick reutilization, e.g.
The template functions you'll find in the trip, route and waypoint editing respectively.
For more information on template creation and reutilization see EDITING.



Warning Messages


What does the warning message mean, that the logging function has been blocked?

LD-Log has determined, that the logging function could not be called and as such future waypoints may not be recorded.
Probably a special power saving function is active on your device, that blocks regularly scheduled tasks, e.g. the Asus Auto-Start Manager. Those - normally quite useful - functions prohibit apps that are dependend on scheduled background tasks from working reliably. Deactivate those power saving functions, or better: Add LD-Log as an exception, if there is such a possibility (for example in Asus Auto-Start Manager: open app 'Auto-Start Manager' -> tab 'Downloaded Apps'-> in list look for LD-Log -> set to 'allow').

What does the warning message mean, that the logging function has been blocked in standby mode?

LD-Log has determined, that the logging function hasn't been called as many times as expected and as such a number of waypoints could not be retrieved.
Probably a special power saving function is active on your device, that blocks regularly scheduled tasks in standby mode, e.g. the Sony Stamina-Mode. Those - normally quite useful - functions prohibit apps from working reliably in the background. Deactivate those power saving functions, or better: Add LD-Log as an exception, if there is such a possibility (for example in Sony Stamina-mode: Settings -> power management -> Stamina Mode -> apps active in standby).
If you receive this warning message, but you cannot find a configurable power savings mode, then possibly a restriction is directly implemented into the Android system like on some Samsung devices with Android versions 5.0 and up. In this case try the advanced options 'Use Alarm Clock Function', resp. 'Use Samsung 5.0+ Fix' in the log settings. Read more under LOGGING -> What is the advanced option 'Use Alarm Clock Function' good for / What is the advanced option 'Use Samsung 5.0+ Fix' good for.
In case you've tried the above settings without success, read more under LOGGING -> What else can I try, if waypoint recording is being blocked in standby mode.

What does the warning message mean, that the GPS showed no activity?

LD-Log has determined, that during waypoint recording there has been no change of the GPS status and as such a number of waypoints could not be retrieved.
Under normal circumstances this can only happen, if another app has already started the GPS and at the same time there has absolutely no GPS signal been available during recording time.
Therefore it seems most probable that the GPS has been blocked by some power saving mode, e.g. the Android own 'power saver' under Android 5.0 up. Deactivate the appropriate power saving function, or better: Add LD-Log as an exception, if there is such a possibility.
This is how you deactivate the 'power saver' in Android 5.0 up: System Settings -> Battery -> Options Button -> Battery saver -> switch off & set 'Turn on automatically' to 'Never'.

What does the warning message mean, that the GPS has been deactivated?

LD-Log has determined, that during waypoint recording the GPS has been deactivated and as such a number of waypoints could not be retrieved.
If you did not manually switch off the GPS or set the location mode to 'battery saving', there might be a power saving mode active on your device, that automatically deactivates the GPS in standby mode. Deactivate the appropriate power saving function, or better: Add LD-Log as an exception, if there is such a possibility.
This is how you correctly set the location settings: System Settings -> Location -> set to 'On' and set the mode to either 'high accuracy' or 'device only'.



Miscellaneous


Why does LD-Log not record altitude information?

Though theoretically possible, the retrieval of altitude data solely by using GPS satellite information is too imprecise to be useful.
Altitude- or elevation-data with a suitable precision can only either be retrieved by using a geo-data-provider (which is not applicable for an offline-app) or through a device-integrated barometer (this possibility might be considered in the future, if integrated barometers become more popular).
You'll have the possibility, however - e.g. through GPX- / KML- / KMZ-import in Google Earth - to get a precise elevation profile subsequent to your trip.

Can I uninstall the free version of LD-Log, if I installed the full version?

Yes, you should do that in order to free storage space. In advance make sure that you imported all trips from the free to the full version if desired (after installing the full version go to the main option 'Saved Trips' there). It is highly recommended to also delete the whole folder 'LD-Log FREE' afterwards. Especially maps storage in the subfolder 'maps' but also unused image files may take quite some storage space that should be freed. You might want to backup this data on your computer and/or transfer some files to the LD-Log folder in advance, in case you'd like to access some data like offline maps, screenshots etc. at a later time.



6.) Limitations in LD-Log FREE

With the free version of LD-Log you can completely log your ways, attach information to waypoints and export in any supported format.
From version 6.5 it is now also possible to use the sail mode, the trip export / report and many more functions that previously were only available in the full version.
Furthermore all advanced features of the full version (compass, destinations, images, tracking) can be tried out.

Limitations of the free version in comparison to the full version in detail:
