Hi Andrzej, okay, now I see what happens. You feed a map containing a big part of Europe to splitter, and you want to cut out a rectangular area covering Germany, and this part should be devided into 5 tiles using the --num-tiles=5 option. Correct? So, this is a special case as your bounding polygon is already a rectangle. I'll see if I can add code to handle this case.

Now I get 5 tiles which is ok. Probably my previous input data contained duplicated ID numbers. As for split with --num-tiles=5, I get info: "Polygons are ignored because parameter --num-tiles is used" I guess it is about --polygon-file parameter. If bounding poly is not used, then tiles can be bigger. I think you could convert polygon into bounding box to limit area. Without bounding poly, calculated aspect ratio is of no use for tiles at boundary. I'm attaching logs for splitting, there was no densities-out.txt. -- Best regards, Andrzej _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
