Cool. It is also worth noting something that osmcut (an other map splitter) does. It has two modes; one where a map is used for when the input file is small and another where a list is used and the node-id is the index into the list. The later is used for splitting the whole planet file. The second method uses less memory where the memory wasted by node-ids that are not in use is less than the amount of memory used by storing the node-id plus the memory wasted in free space in the hash maps. As currently most nodes are used (about 88%) this is a big win on the whole planet file, while still giving access to the node ids. I've committed the patch. ..Steve _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
