It will not be in planet.osm. Planet.osm will be clean of external sources. > Yes, they may download and use the external source; some will, some won't, > some will only once; some will update regularly.

Taking data from external sources would not be hard: you just update your osm2pgsql app with the one with OMM support, and add flag --include-external-sources during import. I am a bit more worried about probability that some of the external sources are not available from time to time, temporarily or even permanently. To solve this I see three options: a) live with it, contact providers to provide stable API b) cache external data in OSM/OMM central cache/backup service. At least sources which allow caching b) create weekly planet-with-externals.osm.pbf file, which would be in principle same as cache (more precisely proxy), just all-in-one and easier/quicker to use. This would even work also with old osm2pgsql. -- Jaak _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
