Hi Wolfgang, I've described splitters algorithm as it is now here: http://gis.19327.n5.nabble.com/Problem-with-splitter-tp886p5561551.html I am now working on a first approach that looks like this: pass 1: calculate tile areas pass 2: a) for each coord, way: find out all tiles that are

Hi, I have compiled world bounds using the performance branch. They can be downloaded from http://www.navmaps.eu/wanmil/bounds_perf_20120313.zip. I have checked the coverage of different admin_levels with the BoundaryCoverageUtil. The result for admin_level=2 can be downloaded from

Hi Gerd, your description of splitter's algorithm is in accordance to what I observed when I used some simple test data. But beside the mulitpolygon problem there is another issue that results from the present algorithm. If you consider one single tile, splitter writes a certain node to that
