Hi WanMil, this doesn't seem to work. I still see the tag in the precompiled sea data: <tag k="natural" v="sea"/> <tag k="mkgmap:cache_area_size" v="1048709826.5"/> I don't fully understand the idea. The current implementation seems to calculate the value when precompiling and avoids recalculation when reading the precompiled data. Gerd P.S. I found some nice performance improvements for the precompSeaMerger. Reduced run time from 2200 sec to ~330sec. The most important change is to use BoundaryUtil.addToPath() instead of Area.add(). See attached patch for the high-prec-branch. I'll probably move the code for addToPath() from BoundaryUtil to Java2DConverter.

Avoid precalculation of area size for sea polygons created by the SeaGenerator.
For all sea polygons the area size was added as tag which increases the file size of the sea tiles but does not really help. The size only calculated the size of the sea in one sea tile and it's a bit random where the borders of a sea tile are. So the area size is not usefull. _______________________________________________ mkgmap-dev mailing list
