I am working on some extension for OTP (using OSM-Dataset).
More presisely I am using OSM-taggings of buildings and sights to parse potential “Landmarks”/“Features” for a routing algorithm. To get even more Data I check Wikipedia-articles with the coordinates of the OSM-Building.
Now nearly everything is done and I want to test my prog on some smal maps. I have to filter a lot of the osm-data, course they are mostly imperfect. (f.e.building high is set very seldom)
So my question is:
Does anyone know a region, where OSM-Data is most groomed? And/Or a region where as many Wiki-Artikles (with georeferences) exist?
I think maybee there was a research in the past years, where entusiastic people/studens added nearly everything to OSM in their test-region?
Or maybee someone with huge database knowledge could sort out a region with high density of Tag-Infos?
PS: German or at least European regions would be best.
