« Edit zone » (seen from above): drag inside the zone, or its corners; two fingers inside it resize and turn it. Tap a dot of the guide to pin it: resizing and turning keep it still (tap it again to unpin). Tap the size to type it (« 800 », « 500 × 1000 »). Up to 2 km for now. « Done », « Generate » or a long press on the zone lock it: then every gesture moves the map (a long press unlocks it).
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.
