weired housenumbers in Canada
Hi all, in Canada, a lot of OSM data comes from imports, e.g. source=NRCan-CanVec-8.0 or NRCan-CanVec-10.0 I think the house number data provided by these imports is more or less garbage. I see many ways like this: http://www.openstreetmap.org/way/133338396 It is an addr:interpolation way connecting two different points which both have addr:housenumber=5 addr:street=20th Sideroad In many cases I see two of these meaningless objects, one with source=NRCan-CanVec-8.0, one with source=NRCan-CanVec-10.0. I think the only way to handle this data is to ignore it, if mkgmap finds an addr:interpolation way connecting two equal numbers, we should ignore the numbers. Right? Gerd

Hi, the last days I've worked on code to separate plausible from unplausible addr:interpolation data. I think that 10-20 % of all address data in Canada looks wrong or is duplicate or both. Even worse, the data is extremely detailed, so maybe one has to know a trick to use it, else I think it should be removed. What would be the right place to discuss that? Gerd Thorsten Kukuk wrote
