Yesterday I saw that the hospital in construction in Mechelen looked like a real hospital on the map, though it was surrounded with an area “landuse=construction”. As I am a beginner I dared not change this. I placed a note, and as this area on the map is not a canvas for notes pointillism yet, it was quickly discovered and corrected by a more experienced mapper. osm.org/#map=17/51.05150/4.47494
