What if OSM data is wrong? What if OSM says "The river bank goes up to
here" and it doesn't, and that would make the tree in the river.
Which is a valid point because you are suggesting:
The usual approach would be to automatically analyze the data in
combination with the OSM data to identify the cases with possible
conflicts and then to manually review only those.
To which I am replying that is an invalid way of validating data because
that would be a presumtion that OSM Data is 100% correct and accurate,
which it is not(aligned to misaligned imagery is an example of why it could
Maybe understanding the logic flaw I'm trying to express in your "analysis"
would be a good place to start.
