The pass
Choose a parcel. The pilot flies. The app records the position, the height, and the heading, then a picture when the camera has seen new ground. Finish closes the pass.
The parcel map draws the same surface as a phone walk. Pale patches stay. Open a square for the pictures that made it. If nothing was recognized, the square says so.
