[Talk-ee] verbatium buiding import discussion

Hi everyone!

I'd like to discuss the import made by verbatium in 2008:
https://www.openstreetmap.org/changeset/569055
(...and other similar changesets)

There are two issues with that import:
1. Unknown data source with unknown license (probably it was a Garmin map judging by the Type=0x13 tag)
2. Poor quality of the data. If you see a building distorted like this: http://svimik.com/verbatiumimport1.png
- you can be sure it's verbatium's. Maybe it was OK in 2008, but in 2019 we have much better options.

What can be done:
1. Remove all buildings which geometry and tags were not edited since the initial import. For the tags the following exceptions can be made because they were automatic edits:
- User xybot has fixed the tag typo (buildung=yes) in the initial import and added its own tag (created_by=xybot)
- User juhanjuku has removed the Type=0x13 and created_by=xybot tags
- User SviMik_import has imported the address tags to these buildings from the Maa-amet database (nothing that can't be imported again)
2. Proceed with the Maa-amet building import as usual

It will solve:
1. The license issue (if there is any)
2. The quality issue (if you agree there is an issue)
3. Will update the map in general, for example the demolished buildings will be removed from OSM.

For buildings which geometry was changed by other contributors after the initial import - we can assume both license and quality issues were solved since they no longer contain the imported geometry. I know it's a grey field, and I'm not sure it works like that, but at least these buildings do have some excuse to stay.

For buildings which geometry was NOT changed, but some POI tags were added - let them stay for now and discuss it later if needed. I suspect it will be a rare case, but the exact number is unknown right now.

Questions:
1. Has anyone else digged into the issue, maybe asked verbatium himself?
2. Can anyone confirm that the import indeed has the license problem?
3. Is the proposed plan good? (in case if you agree that it needs to be fixed)
