Hi Gerd,
As the comment says, this polygon is not closed. The trunk version ignores this error and creates a shape. Is this intended?
Yes, this is standard for polish format. Cgpsmapper would probably complain if you close a polygon. I think there are still some basic problems with mkgmap regarding polish format. For example: [POLYLINE] .... Data0=.... Data0=.... [END] This object should create 2 separate lines, I think mkgmap connects them, which is wrong. [POLYGON] .... Data0=.... Data0=.... [END] First "Data" should be treated as outer polygon, second and following as inner (hole). I'm not sure, what is doing mkgmap but i remember that something is wrong with polygons too, there are wrong shapes on map. -- Best regards, Andrzej
