You have absolutely shown a number of cases where there was no merging and the TIGER data was simply splatted over existing data. This is certainly one of the downsides of the approach that was tried before. I uploaded Oregon first because I had already talked to all the mappers in my own state. I then proceeded to upload all the states that were completely empty. After that, I used this map: http://ted.mielczarek.org/code/osm/counties/ and uploaded only counties that were virtually empty. Interestingly, people started contacting me pretty quickly saying "you missed my county!" That's because the areas with the most data were also the places with the most active mappers! Almost all the prolific mappers knew that they could never compete with the pure amount of TIGER data and went to the heroic effort of merging their existing work with it. In the end, I think there was only a single county (out of ~3000) in the US that didn't get TIGER data in one way shape or form, and I gave people plenty of time to decline. So, I completely disagree that the merging can and should be done manually. There's simply too much data. It's also not feasible to blacklist every county that has *ever* had a single edit. But, I don't want to "corrupt" anything. Just as before, I'm going to let all the decisions be made by the local mappers. If you're concerned, please stay on this list because I'll always announce things here (at least). -- Dave _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-us
