Hi, I have taken US DOT bridge condition appraisal data and created a regionated KML visualization: see post at http://www.thedaysarenumbered.com . However, almost all bridges are not geolocated correctly. I wonder if someone can recommend a way to use OpenStreetMap to edit the bridge information so that, on one hand, the bridges are added to the map if they are not there already, and on the other hand, so that the corrected bridge coordinates could be extracted and given back to DOT (as a way of saying thank you)?
I got somewhat contradictory advice on IRC. So far I gathered that it's technically possible to just import the 180k entries into the base layer (the total bridge count is actually 700k, I'm just showing the lowest quartile). However, connecting the uploaded bridges to the real ones (if those are present) may not happen for a while, so the map will become littered. Automatically matching the bridges will hardly work in most cases. I'd prefer to add bridges to a hidden layer first and only push them to the base layer once data are verified. BTW, I was pleasantly surprised when the OSM California road dataset proved to be much better than the one the state of California provides.
