I don't know about the file you specified, but I have been trying to figure out how I could edit Waypoint.gtk to use this thing for geocaching. Made a breakthrough today, and decided I didn't want my top Google result for trying to figure this out to not to have any good info. It uses a 64 bit floating point format for latitude and longitude.
Lat-Lng pairs are (relative addresses in that file):
* 0x18, 0x20
* 0x30, 0x38
* 0x48, 0x50
* 0x60, 0x68
* 0x78, 0x80
The four bytes (out of eight) that immediately follow each pair look like they could be a 32-bit UNIX timestamp, but for some reason they're all the same for me, at least in the Waypoint.btk file.
