World map generation - portapack-mayhem/mayhem-firmware GitHub Wiki

The Release package includes a map, however you can create your own following simple rules:

• world_map.jpg should be square (i.e. 32768 x 32768 px)
• The projection of the map is Mercator based on the World Geodetic System (WGS) 1984 geographic coordinate system (datum)
• Longitude and latitude cover the map from -180 to 180 and -85 to 85, respectively. Note that latitude does not go up to 90 (since most available maps do not include the 5 initial degrees)
• Center of the map should be 0-degrees latitude and 0-degrees longitude (where the prime meridian and equator intersect)

With those conditions fulfilled, place the input map in: sdcard/ADSB/world_map.jpg and then run firmware/tools/generate_world_map.bin.py. Your map will be generated on: sdcard/ADSB/world_map.bin
