Hi,
as already discussed on yesterday's Stammtisch, I have made a simple page that shows all nodes in Switzerland that have been created by anonymous users:
http://osm.lonvia.de/anonymous_edits.html (Careful, big file. Loads _really_ slow and may even crash your browser on older machines.)
The page is updated once daily.
For these edits there is very little chance, that the creators will ever agree to ODbL/CTs, so this data needs to be remapped sooner or later.
Before you now go and delete all the data, please, keep two things in mind:
- The map only shows the nodes but the ways that go along these nodes are, of course, tainted as well. So, you will need to remap the nodes _and_ ways that are made up by the nodes. - Don't just copy the old data but take the opportunity to improve it. Go out and survey the area again and fix a few errors along the way. Check if there are maybe better aerial photos available now that will improve accuracy, etc. In any case, you cannot simply make a copy of the old data and be done with it. You must have an independend source for the replacement data.
Happy mapping
Sarah
