I believe there are many uses for an extension of the address interpolation concept to data and surveys of less than 100% accuracy.
- Survey of streets of new construction where the endpoints are known, but not all houses are yet present. - Survey of streets of new construction where the endpoints are not known, but a possible range can be estimated. - Use of US TIGER data to indicate all possible addresses on a block; useful for routing to the nearest block where no survey has been done. - Survey of established communities where house numbers are missing or damaged beyond recognition. This is often coupled with irregular numbering in which it isn't known if a house lot size = 1 or lot size = 2 (takes one numbering slot or two). Since a survey was done, the house could still be accurately Geo-located without the mapper knowing the actual number. The question is how to tag these. I've seen something like addr:inclusion=actual -> Exact survey; the traditional meaning of the Karlsruhe Numbering Schema addr:inclusion=estimate -> The address interpolation way may contain numbers that don't actually physically exist. A survey has been performed, and Geo-location would be very close. addr:inclusion=potential -> The complete range of all possible address numbers on a block, although there may not physically be enough room on the block for that range of house numbers. From US TIGER for example. Geo-location would only be as near as one block. There are more accurate English terms, but they are very verbose. Any other ideas. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
