Agreed about having to deconflict after buildings are imported on top of other buildings. I didn't see any suggestion of that in Jason's process. <div><br></div><div>In Seattle, we're looking at doing a manual comparison of each building way provided by the city to the building ways already in OSM. Essentially, manually copy the new buildings into the OSM data layer in JOSM, identify duplicates, compare, make sure all tags are kept in the desired way, then delete the undesired way, move to the next one.
