[mkgmap-dev] Did anyone realize cGPSmapper speaks Garmin NT?

Hi list I remember many discussions and comments about how mkgmap produces Garmin's legacy format only and the NT format is still a mystery. Today, I was pointed at a discussion of the Polish UMP project (similar to OSM, strongly concentrated on Poland and surrounds). As I happen to be Polish and thus read the language, I browsed their wiki. I noticed that they are producing Garmin NT maps. And then I found that their tool chain is based on cGPSmapper [1]. So, is the Garmin NT format considered reverse engineered now that the cGPSmapper source is open? Or has this interesting fact been missed somehow (I certainly was unaware of it until today)? - Bartosz [1] http://ump.fuw.edu.pl/wiki/Kompilacja_mapy
