Don't get lost

Lokalsinne guides you in the Scandinavian wilderness.

Lokalsinne is a navigation app that displays your location on a map of the terrain. You can save places you want to find your way back to. You can share your location or places you have saved with others. You can also record tracks of your movement and save or share them. Maps can be automatically downloaded when needed or manually downloaded in advance. You can choose between Swedish maps from Lantmäteriet or Norwegian maps from Kartverket.

Get Lokalsinne at Google Play.


Karta

Lokalsinne is a Swedish word for the skill of a pathfinder. To have lokalsinne means having a good sense of direction and knowing your surroundings.

Map

The map is displayed north up no matter how you turn. Your location is displayed as a red circle. If a blue semitransparent circle is displayed around the red circle it means that your location is uncertain and that you can be anywhere within the blue circle. The WGS84 coordinates of your location is displayed above the map as degrees with decimals.

By default the map moves when you move and the red circle that represents your location remains in the center of the screen. But as soon as you pan or zoom the "center and follow" mode is disabled so that you can study the map without it jumping back to your location all the time. When you want to go back to the "center and follow" mode, simply tap the My Location icon.

You can name and save places by doing a long press on the map. Saved places are displayed as a location icon (the black upside down drop formed shape). If you select a saved place (by tapping it) Lokalsinne will display the name of the place and the distance to it. In the picture above a place called "Bilen" is selected. As long as a place remains selected the name and distance is also displayed on the start screen. Tap the icon again to de-select it, or tap the displayed name.

My Location

My location Centers the map at your last known location and follows your movements so that your location remains in the center of the screen.

Search

Search The search function allows you to search for towns, mountains, lakes, etc by name. Lokalsinne relies on OSM Nominatim Webservice to look up the name you search for. This means that the search function will not work if there is no internet connection.

Save Place

Save This is used to name and save your current location. Once saved, it will be displayed in the list of saved places and appear on the map. The place is saved in your device and cannot be seen by anyone else unless you share it.

Share

Share You can share the displayed map, your current location or a saved place or track with others. To share a place or track, you must first select it before you tap Share. When you have selected what to share, a list of apps will be displayed. Select the app you would like to use to share the information. When the app is displayed you select who you want to share with. Places and tracks are shared in Google Earth format (kml). Maps are shared in JPEG format (jpg).

Compass

Compass If you select Compass from the menu, a compass rose will be displayed instead of the map. The compass rose is automatically rotated so that its long red peak points to the magnetic north pole. When using the compass, make sure you keep the device level with the ground and the screen facing up. There are scales at the side and the bottom of the screen that shows if the device is level or angled.

If you have selected a place, a location icon will also be displayed on the screen. To find the direction to the place, simply turn around until the location icon is displayed right above the center of the compass rose.

The compass will not work if your device does not have the necessary sensors built-in. If the compass is working the rose will rotate if you turn around. Be sure to check if the compass is working before you trust it!

Unlike a magnetic needle compass, an electronic compass will need calibration from time to time. If the compass rose does not turn a full circle when you turn a full circle, it is time to calibrate. To calibrate, rotate the device around each of its three axes while the compass is displayed. You may need to repeat these motions a few times. You can also try moving the device around in a figure 8. If none of these motions help, your device might require some special calibration procedure. Check the manual of your device or contact the device manufacturer for advise.

Places

Places If you select Places from the menu you will see a list of all your saved places. By selecting a place from the list you can perform the following actions:

You can enable multi-selection mode by a long press. Select as many places as you want. Tap the check mark in the title bar to end multi-selection mode.

Tracks

Spår If you select Tracks from the menu you will see a list of all your saved tracks. The Record button is used to start recording a new track. Your movement is displayed as a black line on the map while recording is in progress. The Stop button is used to stop recording. When you stop a recording you will be asked if you want to save or delete the track. The track is saved in local storage and cannot be seen by anyone else as long as you do not share it.

If you select a track from the list you can perfrom one of the following actions:

You can enable multi-selection mode by a long press. Select as many tracks as you want. Tap the check mark in the title bar to end multi-selection mode.

Map Tiles

Kartor When you select Map Tiles from the menu a screen is displayed where you can toggle automatic download on/off, manually download map tiles and handle downloaded map tiles.

Automatic download

When automatic download is enabled Lokalsinne will automatically download missing tiles when they are needed. You have the option to disable automatic download. If automatic download is disabled the screen might be empty where map tiles are missing. The same thing can happen even if automatic download is enabled, if there is no internet connection or the selected map source is not responding. Automatically downloaded map tiles are only stored as long as needed.

Manual download

The map is divided into tiles. To download and save a map tile first select the tile you want and then select Download. Map tiles that you have downloaded will be saved locally in the device and can be displayed even if there is no internet connection. This is useful if you are going somewhere without coverage.

In Android 5 and later its possible to save the map tiles on a memory card.

Manual and autmatically downloaded tiles are displayed in the same way and normally you will not be able to tell the difference.

Map Sources

Kartkällor You can choose between Lantmäteriet for the Swedish map and Kartverket for the Norwegian map. Select Lantmäteriet when your are in Sweden and Kartverket when you are in Norway. Please note that if you are outside the selected map you will only see the red circle of your location and no map.

Availability

If you do not receive any map tiles it might be because of a planned or unplanned downtime of the map source. You can find information about the current status and planned maintenence here:

Content

The maps are updated continously by Lantmäteriet and Kartverket. You will always get the latest version of the map when it is downloaded. Manually downloaded maps are not updated automatically. To get a new version of a manually downloaded map you need to delete it and download it again.

If the map is incorrect or out of date, first make sure you are looking at the latest version.

Report errors in the map of Sweden to Lantmäteriet. Use this page and select "Topografisk" as the type of map that contains the error.

Report errors in the map of Norway to Kartverket. Start here and enter "Topografisk norgeskart 4" as the name of the map that contains the error.

Premium

The basic version of Lokalsinne is free. You can uppgrade to Premium by choosing Buy Premium from the menu. The basic version is limited to saving 10 tracks. There is no such limitation in Premium. That is the only difference between the basic version and Premium right now. There may be other Premium functions in future versions.

Tracks and places from other sources

Lokalsinne can show tracks and places that you download from websites or someone shares with you. The two most popular file formats for exporting or sharing tracks and places are GPX and KML. Lokalsinne can read both formats. One file can contain multiple tracks or places.

When you install Lokalsinne it is registered as an app that can show GPX and KML files. This means that when you open a GPX or KML file, Lokalsinne will start and import the contents of the file. If you have more than one app that can read the file you are normally asked which app you want to use. If the file is opened in a different app without asking if you want to use Lokalsinne, it probably means that the other app is configured to be the standard app for that file type. To change that you need to go to the settings for that app.

Accuracy

Lokalsinne uses satellite navigation to calculate your location. This is usually called "High accuracy location" or "device only location" in Android. Satellite navigation works by listening to signals from multiple satellites in space. The accuracy of the location depends on the quality of the satellite receiver in your phone and current reception conditions. The rule of thumb is: the more you can see of the sky the better satellite navigation will work. But there is a huge difference between how good different phones are at receiving satellite signals.

Navigation using WiFi or cell towers usually work better than satellite navigation in citys. The reason for this is that in a city the cell towers and WiFi hot spots are close together and the houses block much of the sky. In the country-side the opposite is true. Since Lokalsinne is intended to be used in the wilderness it uses satellite navigation.

There are more than one satellite navigation system. The most common one is the Global Positioning System (GPS). Which system is used by Lokalsinne depends on which systems your phone supports and which satellites are within range.

Don't expect the length of a recorded track to be exactly as long as the path you followed. A track consist of a limited number of stored points. The length of the track is calculated by assuming a straight line between the points. In reality you seldom move in straight lines which means that the calculated length usually will be shorter than the real travelled distance. A difference of 10% is quite common when following a winding path.
