Holy cow!
United Maps' UM-DE, our comprehensive map of Germany on hyperlocal scales consists of 101.629.970 datapoints. Slightly more than one hundred million.
Of course that's comparing apples and pears - however the volume is amazing. Compare this to your conventional datasets and you'll like see a tenfold increase in data: streets, places, POIs and much more you won't see on conventional services.
By the way: here's our latest company profile, detailling what it's all about - German and English versions.
#1 Substract 295 items from "Building Footprints"
#2 Point Addresses are yet without Saxony and Bremen
All in all, it doesn't make a difference.
