we had sort of precedence with the official ALKIS land register data and the JOSM Tracer2 plugin in the state of Northrhine-Westphalia in Germany, where we were allowed to use the official land register layer to trace building outlines. (Permission to use that data was removed a while ago, but has just recently been restored again) Tracer2 wasn't really anything that I would call an AI, but it most of the times did a good job in copying building outlines from the ALKIS layer by doing simple image tracing. You just had to click inside the building outline in the ALKIS layer, and Tracer2 would add the building outline to the OSM data layer. So this was sort of an automated import with human filter on an object by object basis, too. But we also learned from that: * do not blindly trust the official data * compare it to a second source, to the most recent aerial pictures at least, but on the ground always wins With the current topic at hand, aerial images would not really be a true 2nd source, as the AI would also extract its suggestions from these to begin with ... _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
