Most of it was based on NIMA data, with 1/10 minute precision Much data has been added since. I don't know how this data should be added best. When you import everything, you will have lots of duplicate places. My recommended approach and current work is to add the best reference, which is the location id of the currend way or node. Take e.g. the road I live in: http://www.openstreetmap.org/?lat=48.0255&lon=7.8644&zoom=12 It's within Freiburg, Baden-Württemberg, Germany The town district is named Zähringen (about 1000 years old). Its loc id in opengeodb is 81730: http://fa-technik.adfc.de/code/opengeodb.pl?locid=81730;c=D There's not much info about this district, thus it may share its data with its parent Freiburg through its "part of" relation: http://fa-technik.adfc.de/code/opengeodb.pl?locid=16633;c=D base data is e.g. its abbreviation (car plates), inhabitants, postal code, telephone prefix, area,while there may be added extra data such as height, different names in other languages etc. Svens approach is to move most of the data to OSM. Personally, I'd prefer to take only a subset for reference, while most of the roads should have a loc_id tag about the district where they belong to. - Martin _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
