Well at this moment it's an ordinary sorted list :) But it might be a good idea to use an advanced index for the tile to ways index. The index is stored as sequential serialized structs. To load a required nodetile from disk I'll seek through the sequential dump of nodetiles which have a fixed record size. The nodes are already sorted by id in planet.osm. By guessing an address and watching the value I'll know to look forward or backward. gr Dick _______________________________________________ dev mailing list dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/dev
