Do we have the encodings somewhere? I got my values from the GroundTruth manual page:
The initial information I found was in the Garmin IMG format document: http://sourceforge.net/projects/garmin-img/ However this document only lists the 6-bit encodings. The most complete document which I found was the cGPSmapper manual: http://cgpsmapper.com/manual.htm This document lists eleven codes, and gives both the 6-bit and 8-bit values. (There are nice pictures too.) For example, the large highway sign is ~[0x2d] in 6-bit and ~[0x04] in 8-bit. There are also codes for US highway symbols; apparently these labels can only be numeric, which presents another challenge for anyone wishing to implement these signs. Cheers.
