Based on the data source website the geometry source data is from 2006
and 2008. Depending on the area quite a lot of things can change in
the third data source link is broken.
On the whole the plan looks solid but it seems somewhat vague in some
parts to me at this time:
- there is no information on tagging
- there is no assessment of the geometric accuracy of the source data
- there does not seem to be any abstract specification coming with the
source data - it would be important to know if it complies with
established OSM practice of building mapping, in particular w.r.t. what
constitutes a single building and when there are two separate buildings
and possibly building:part.
- it would be important to know what age and accuracy available image
data sources have for the area of the import.
There are also some previous building imports in the area - like:
It would be a good idea to include cleanup of these with the import
