You find the maps that are stored on the smartphone under ‘Maps’ in the main menu.

If you like to add new maps to the app then follow the instructions under ‘Georeference map’ below.

If you want to remove a map from the smartphone then click and hold on the map in the list until the dialog ‘Delete’ is shown.

When you have selected a map it will be shown. You can zoom either by multi-touch or by using the zoom-glasses. The zoom-glasses are only shown if you have enabled them in the ‘Settings’ menu.

Your current position will be shown if the map is georeferenced and you have turned on the GPS. The position is indicated by a blue dot. The accuracy of the GPS is also shown. This helps you to see if the map is correctly georeferenced.

 Georeference map

You need an orienteering map in digital format. The map file shall be in jpg-, png-, gif- or tif-format and it shall have correct coordinates (longitude and latitude). Modern maps drawn in for example OCAD usually have correct coordinates whereas older, hand-drawn maps can contain skews which makes them unsuitable for GPS orienteering.

Georeferencing can be done either by setting the coordinates for two fixpoints, use a world-file or a kml-file.

We suggest that one person in the orienteering club is responsible for creating the georeferenced maps and to distribute them to the other club members.

To create a georeferenced map:

1. Create a orienteering map in jpg-, png-, gif- or tif-format. The best is to use the program OCAD and choose the function ’File/Export’. The resolution of 300dpi or 600dpi should be used.
You can also scan a paper map be aware of that it may contain skews that will make it hard to calibrate the map. There are also maps on for example and

2. Put the jpg/png/gif/tif-file on the SD-card of the smartphone in the folder gpsorienteering/maps by connecting the smartphone to your PC with a USB-cable, enable file transfer on the smartphone and use the file explorer to copy the file to the smartphone. (If the directory does not show up in the file explorer, then restart the smartphone to force a media scanning of the SD-card.)

3. Georeference the map by defining the coordinates for 2 fixpoints on the map. Choose points that can be exactly defined and that are far apart. The best is if the person who has drawn the maps can give exact coordinates for the fixpoints, but it also works excellent to go to the points and use the smartphone GPS for setting the coordinates or to use the service to decide latitude and longitude for the fixpoints.
a. Open the map that you want to georeference.
b. Select ‘Edit map’
c. Zoom, select ‘Set fixpoint 1 on map’ and click on the point that shall be fixpoint 1
d. Do the same for fixpoint 2.
e. Select ‘Set fixpoint coordinates’ and enter the coordinates for the two fixpoints. Save the coordinates by selecting ‘Save fixpoint coordinates’.
f. You can also enter scale, owner etc. under ‘Edit map info’ if you like.
g. Select ‘Exit edit mode’ to leave the map edit mode’.

4. The map is now georeferenced and you can give the georeferenced map to your club members, and you can start to create courses! See ‘Share maps’ below or use the built-in function to share maps via Bluetooth. Or publish the map to make it available for all users, see ‘Publish a new map’ below.

Use world-file for georeferencing:

If you have a UTM-based coordinate system, then you can use a world-file (.jgw/.pgw/.gfw/.tgw) to georeference the map. When you export the map in step 1 above, then also export a world-file (in for example OCAD 10 or higher). Put the .jgw/.pgw/.gfw/.tgw-file together with the jpg/png/gif/tif-file in folder gpsorienteering/maps. When you open the map in the app and select ‘Edit map’, the app will automatically use the world-file for georeferencing.

Use kml-file for georeferencing:

You can use Google Earth to georeference the map. Start Google Earth, choose ‘Add / Image in 3D-view’ under ‘My locations’. Set the link to the map and use the tools in the program to georeference the map. Make the georeferencing as accurate as possible! Then create a kml-file by selecting ‘Save location as..’ and select the format *.kml and give the file the same name as the map. Put the kml-file together with the jpg/png/gif/tif-file in folder gpsorienteering/maps. When you open the map in the app and select ‘Edit map’, the app will automatically use the kml-file for georeferencing.

Share maps 

You can upload the map to the server, if you want to share it with others. Select ‘Upload map’ when you have opened the map. The map has a unique code (8 characters) that is used when downloading it. You can copy the code to the clipboard and paste it into a text message, email or similar and send it to others for download.

The map is stored in an encrypted format on the server.

Select ‘Download protected map’ in the map menu to download a map.

The one who has uploaded a map can also remove it from the server. Select ‘Uploaded maps’ in the map menu and click on the map until the dialog ‘Delete’ is shown. The map will be removed from the server, but not from your smartphone.

Public maps

You can download calibrated maps from internet. Select country and year for the search query.

A list of maps matching the search criterias is shown. When you select a map, additional information is shown and you can download the map to your smartphone. Use ‘Show position on Google Maps’ to see the position of the midpoint of the map on Google maps

Publish a new map

To publish a new map that all GPS Orienteering users can acces the following procedure shall be followed:

1. Fill in and send a request for publication of the map (RFP GpsO map.txt ) together with the calibrated map (i.e. both the jpg/png/gif/tif-file and the xml-file) to . The map should be in A4-format and have a resolution of 300dpi or 600dpi to be printable with sufficient quality on a standard colour printer.

2. HippsomApp will process the request and send a mail to the owner of the map (usually an orienteering club) to get the approval from the owner to publish the map .

3. If the owner approves publication of the map, then HippsomApp will add the map to the database and tell the owner and the person who requested the publication that the map is published.

4. The users can now download the new map using the GPS Orienteering app.
