For those new to this subject, Sam is revisiting street number addressing for the automated import of Canadian data. From GeoBase, some provinces / territories provide "block face addressing" and tell us what street addresses are on a particular section of road. They provide a first and last address for the left side of the road and a first ans last address for the right. When we started the import, not all prov/terrs provided address data. > The purpose is to tag what the house numbers are. > In Canada, > the address block # is posted directly on the street sign.

Calgary and Edmonton? Yep, pretty organized. Lots of other places? Perhaps. But not everywhere. > Rendering: > looking similar to how the 'ref=#' tag is used on highways to show > distance, this would be a smaller font as its only on a closer zoom > that it should be shown. Can you create a prototype of what you are suggesting for the block face addressing please? That would help me to understand what you are suggesting. And, "how the 'ref=#' tag is used on highways to show distance" I don't understand. We use ref to show the highway number. > Data import: > usually, the 'address:house number:first left would be it. - (perhaps > a script could be written to detect the lowest number, then round to > the lowest 100) (out of the 4 fields available) I've already seen a nice prototype of Karlsruhe-style[1] interpolated addresses, automated. Sadly I don't have the link to that code in front of me. Anybody remember it? Best regards, Richard [1] "Karlsruhe Schema" is an organized method of adding address information to a street, either for individual buildings, or interpolated addresses to estimate individual address positions. http://wiki.openstreetmap.org/wiki/Proposed_features/House_numbers/Karlsruhe_Schema _______________________________________________ Talk-ca mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-ca
