Borders and Symbols

Alternative 1: Creating Google Maps Engine - My Maps URLs (recommended)

  1. Open https://mapsengine.google.com/map/
  2. Draw the overlays, e.g. as LineString representing the area border
  3. More information about Google Maps can be found at http://maps.google.com/support/bin/topic.py?hl=en&topic=23523 (ignore "classic Maps" content) 
  4. Export the URL with the button "Share" on top right. Set the access rights to allow "access for everyone having a link", as the app will load it without your user credentials.
  5. Copy the URL which is typically in the form of "https://drive.google.com/open?id=12345...", copy the ID behind the "id=" and append it behind "https://www.google.com/maps/d/kml?mid=", so that you get in this example "https://www.google.com/maps/d/kml?mid=12345...".
  6. To test the URL for correctness open it in a fresh browser window. A KML file with proper content should be downloaded. If the file is empty, your URL is either incorrect or you have no lines and/or placemarks in your map.
  7. Continue with the section below "Loading from URLs"

Alternative 2: Creating Google Earth KML files

  1. Best is to create the files with Google Earth. Google Maps though, can create KML files but they in turn only contain URLs and not the actual shape and placemark descriptions.
  2. More information about KML can be found at http://code.google.com/apis/kml/documentation/kml_tut.html
  3. To validate KML files visit: http://www.kmlvalidator.com.
  4. For editing the KML files have to be changed outside the app and placed again on the device.
  5. Continue with the section below "Loading KML files"
Loading KML files - The files must be in the format '.kml', the compressed format '.kmz' is not supported.
  • iOS: Put the KML file into the documents directory with the help of iTunes File Sharing.
  • Android: KML files must be placed on the SD card in the directory 'ihuntjournal'. A trick to find the right directory is to do a Backup ('Extras' > 'Backup to SD card') - this will create the directory in the correct location with the correct name. Now put the KML file into that directory.
Loading from URLs
  • Obtain the link like described above, send an e-mail to your device. 
  • Open the e-mail on the device, copy the URL string
  • Open the app, enter the  'Map'/'Locations' > 'Area borders and symbols' dialog, paste the URL in an appended new field.
To actually load the KML files or URLs as overlays on the map, open the dialog: 'Map'/'Locations' > 'Area borders and symbols' and press 'Load and save'.
