For OpenPisteMap, I write an updater script: http://subversion.nexusuk.org/projects/openpistemap/trunk/scripts/updater.py (you'll need to hack the paths in the script as appropriate). It basically tries to keep the local database in sync with the OSM server by grabbing the deltas each minute, but it also tries to be smart with whether it downloads the daily, hourly or minutely deltas based on how far behind you are. > FYI: I am not using any OSM tools to do the import, i'm writing my own > import code (i'm in a .Net environment, and I find it better for my > understanding if I do this myself).

Well, my updater script may not directly be that useful to you then (it uses osm2pgsql), but it might be a handy reference. I don't claim it is necessarilly a "best practice" implementation, but I have tried to be sensible with the number of requests it makes to the OSM server. - Steve xmpp:[email protected] sip:[email protected] http://www.nexusuk.org/ Servatis a periculum, servatis a maleficum - Whisper, Evanescence _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
