World_map.bin is required if you want to use the world map view in some apps. It's a huge (~450MB) raw image file in a format that can be easily rendered by the PortaPack.
Since Github doesn't allow uploading such large files, you must generate it yourself from the provided jpg file.
- Make sure that
world_map.jpgis in/sdcard/ADSB. - Go in
/firmware/tools. - Run 'python adsb_map.py'. Give it some time.
world_map.binshould appear ! Leave it in the ADSB directory.
