Hi all, I've just committed r247. Changes: - added parameter --polygon-file to specify a bounding polygon. The polygon is only used when the tiles are calculated, it is NOT used when the real split process runs. - performance improvements in the new split algorithm The polygon file format is that of osmosis, I've simply added the osmosis sources: http://wiki.openstreetmap.org/wiki/Osmosis/Polygon_Filter_File_Format I hope that is the right way to do it. The polygon is only used when no split-file is given. It is used when all nodes were read. In this first pass, splitter fills a grid with node counts. Instead of filtering each node (which would take much too much cpu time), splitter simply uses the polygon to set those grid counts to 0 (zero) which do not intersect with the polygon. When that is done, splitter calculates the tiles.
