The zone moved: « Generate » again.
« Edit area » (seen from above): drag inside the zone, or its corners; two fingers inside it resize and turn it, two fingers on two opposite edges only turn it. A long press anywhere in the zone (corners and edges too) plants the pin: the zone turns and grows around it; drag its round handle to turn it with one finger; tap the pin to remove it. Tap the size to type it (« 800 », « 500 × 1000 »). Up to 2 km for now. Only « Done » or « Generate » lock the zone: then every gesture moves the map.
Real 3D: national LiDAR or official LoD2 (France, Netherlands, NRW, Switzerland). Estimated 3D elsewhere: Overture, then GHSL (90 m cells), in beige. Basic 3D: OSM heights only.
Grey volumes = real heights. Orange outline = building with no real height here.
Tap two points in the area to draw a section line.
