Hi Andrzej, no, it causes lots of problems. For example, the bounding box for planet is (-90.0, -180.0, 90.0, 180.0). If we don't distinct the positions of the left side from the right the area is a line with width 0. The funny thing is that the precision in OSM doesn't even use all possible 32 bit integers, only those for -180 * 10_000_000 to 180 * 10_000_000 so the extreme values near Integer.MAX_VALUE are never used (at least that is the conversion done in pbf or o5m format). I think about using this format for Coord and maybe also Area.

I found new problems, e.g. 180.0 degrees and -180.0 degrees started to give the same 32 bit value.
Isn't it good? The same is true for 24 bit precision and even for 8bit angles. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
