Sorry for the newbie question but after doing a lot of research on OpenStreetMap I am still confused as to how everything works. At this point I have setup my own server with Nominatim so that I can perform as many lookups as I want and add data that might not have the approved OSM license. The problem I am running into is that there is not enough detail in the database. I have tried importing the TIGER data (not sure if it worked) but I am still missing a lot of data. So I would like to import the county property data. The data that I have contains polygon shapes for the parcel and address information. So the questions...
Sorry for being long winded but this has been very confusing to me. asked 26 May '13, 23:42  chung1 edited 26 May '13, 23:43 |
One Answer:
Polygons can be as simple as a way using a list of nodes. They can also be relations of ways but for your purposes a simple way joining a set of nodes is probably best. See the wiki for a definition of the OSM file format. There is currently no convention I'm aware of for importing parcel data into osm so doing this 'correctly' probably isn't possible. See: https://wiki.openstreetmap.org/wiki/Parcel I would suggest tagging the parcels as building=yes and then using the https://wiki.openstreetmap.org/wiki/Addr tags. For your purposes it will probably provide the best result for least work. PLEASE NOTE: This is assuming you are importing the data straight into nominatim. This would not be suitable for importing into OSM database itself. That would be a completely different topic. answered 29 May '13, 18:55  twain edited 29 May '13, 18:56 |
Thanks for the answer. Is there a link that explains the difference between Nominatim and the OSM database. My understanding was that Nominatim used the OSM database to perform the lookup but I think I am a little confused.
