The most interesting clauses in the license is: "Users are not authorized to license, re-license, assign, release publish, transfer, sell or otherwise make available any portion of these Data, or any information from GIS data derived from these Datasets, to a third party in any format revealing Thurston County as the source of the data." This solves the attribution issue quite nicely: we're *forbidden* to credit this data to Thurston County. > The database has 128,639 addresses.

Some observations: * Almost every point corresponds to a building or some other object (eg. a parking lot) that would reasonably be expected to have an address. There are a few oddities, such as a wetland. * There are a few multi-story apartment buildings where the address points don't correspond to the actual locations of the units. * I think you'll want to build street names off the "StreetName", "St_PreMod", "St_PreDir", "St_PreType", "St_PosDir", and "St_PosType" fields rather than any of the other fields. * There are seven duplicate addresses in the data. -- Mark _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
