I would like to add an overlay or track for general public use to the map. This is for a research project http://sabap2.adu.org.za/index.php
This would need to show pentads (these cover 5 minutes of latitude by 5 minutes of longitude (5’ × 5’)). Is there a way I can show selected minutes (5 minutes) on the map?
Alternatively I have these as a track (gpx) that can be loaded. It does not have timer points to the track. I also have it in kmz format for google earth.
Any help would be appreciated.
