I do not think there is anything to gain from the counties that are listed to not be improved. My county (orange county fl.) is one that was NOT improved yet, and in QGIS it looks to be unmodified from the original tiger import. There are not any new tags in the data that would add anything eithe

I consider that your bulk upload script is in exactly the same boat as an automaitc edit script. As such I think that it should adhere to the code of conduct for automatic editors, one point of which is to respect others' edits. To me, this means, don't revert or corrupt others' edits. To achieve

If by "not disturbing existing edits" you include the overlaying of other data on top of existing ones, then I completely agree. Also there are countless non-existant roads crossing the interstates. These have had to be deleted and I agree, must never come back. And yes I agree that any altered t

Ahh but if the tiger data was deleted or modified a comparison to the original would show that, and that way it can be skipped. So either it isn't fixed now, or already has been. Either way I think the new import should default to not disturb the existing edits. Granted even more checking and "s
