Hello. Thanks for mapping on this project. 
A remark.
I noticed that the buildings you map often are a bit, more or less, oversized. Please stay within the rooflines. These huts have an overhang, so they show to be bigger than they are. Zoom in (IDeditor) till at least 40 ft. to have a good view to map a building.
