I did a quick ogr2osm conversion on the street data from here: ftp://ftp.oregonmetro.gov/odi/Streets.zip
I stuck it up here: http://daveh.dev.openstreetmap.org/portland/ I loaded it in (JOSM takes ~1.2GB of RAM doing this), along with some downloaded OSM data. Then I set the "inactive" color to a nice, bright pink, and selected the downloaded OSM data layer. The streets that aren't in OSM already stand out pretty clearly: http://daveh.dev.openstreetmap.org/portland/josm-ping.png Wherever you see pink, there's potentially a problem. It might be a misaligned or missing OSM road. This doesn't guarantee the names are right or anything, but it's at least nice to get a handle on how complete the OSM data is and how well it coincides with Metro's. I'm fairly impressed with how OSM stacks up. It's also neat how much of the "missing" stuff has actually been traced from imagery, but just needs names stuck on it. If this looks like something that might be usable for doing a manual import of new streets, we can probably work on a nicer JOSM style file to make the process even easier visually. -- Dave _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
