Yes, that's the work flow at the moment. But it should be feasible to have daily updates. Also, I am working on a distributed > Also, you warn the user against using the planet.osm as it takes lots of CPU > time. Have you tried? How much CPU, memory, etc.? How long did it take? I do not have any numbers for the planet file yet, but I can give you the numbers for the Western Europe file that powers the demo. extractNetwork: 8 min, 2.9 GB RAM, 600MB Disk createHierarchy: ~5min, 1.5 GB RAM, 600MB Disk routed: ~1min startup, 1.5 GB RAM Brief tests by a colleague showed that parsing the world file and extracting the road network takes about 90 minutes. Preprocessing the data takes another 45-60 mins and something like 15 minutes to start. All this was done on a machine with 64GB of RAM. Please note, that the speed and memory requirements of the road extraction shall improve with the future releases.
