Open the fiche, then press 3D. The full label is Map in 3D. The walk asks for the camera, location, and the phone's direction. Press Start the walk.
Where it stops
A vine stops at each plant. Corn stops every 8 m. Wheat stops every 12 m. One picture at each stop.
The field surface
Pale patches are ground not yet seen. Open a square to see the pictures that made it, and the plants that were recognized. If nothing was recognized, the square says so.
When the list sits beside the map, the same button shows a code. Scan it with the phone. The code lasts 15 minutes. An expired code sends you to sign-in.
