Hi, I read the documentation.
About 1) yes, you have a point about building shapes. I did mixed them up with building plot sizes instead.
If the images from satellites are not accurate (enough), how where the building shapes created then?
About the quality of the region I edited, it was not good at all in the first place, as the site has evolved a lot since 5 years.
About 2) you should explain me why "fancy details" fields are present while you don't want me to fill them in? And why were they empty if you pretend to know already that information? Maybe you know it but the system apparently not because it is not showing it.
About 3) I don't know what you are referring to.
About 4) I did not touch the VUB campus at all. It would be nice though to know how a plane can be formed from lines. This is very useful for splitting a plane in 2.
