I initially just sent this to Ian Dees, but maybe there are others on this list that are thinking of doing this or could help.
Considering the upcoming license change and it's impact (many roads that may become missing), I was thinking more about using TIGER 2011 to find roads that seem to be missing in the OSM database. My PostGIS skills are nil, but it seems like it should be a fairly trivial query to buffer the OSM ways and find TIGER segments which don't intersect the buffered ways. Hardest part will then be scaling this up to all 3140 counties. Later we could continue to utilize the resource by extending this work to progressively get more intelligent by splitting ways into two node segments to get more accurate results, and maybe do string matching to highlight name problems. Oh and flagging of erroneous data in TIGER. And maybe stats per county, and ... This requires hardware resources and people with skills to manage the large database and ideally move towards weekly/daily/minutely updates, and to generate tiles showing the missing segments. Anyone interested in helping with this? -Josh _______________________________________________ Talk-us mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-us
