[OSM-talk] GroundTruth v1.3 - Garmin maps with relief contours

[Igor Brejc]

Hello everybody,

GroundTruth, a mapmaking software for Gamin GPS units, has a new 
version. GroundTruth can now generate relief contours from SRTM data 
using the Isohypse Binary File (IBF) format. The format enables much 
more compact storage of contours (up to 100 times smaller than using OSM 
XML files).

If you're interested, here are some links you can check out:

I'll be releasing a C# library for manipulating IBF files soon.

Enjoy,

Igor
