TERRA Lab EXPERIMENT · STARTED 6 OCT 2026

On foot

Where you stand

Stand anywhere on a sample land and the reading tells you what it found on that spot: the ground under your feet, the nearest water line, the boundary, and where the rain goes from there.

Your position stays on your phone. The page places it on the map and keeps nothing.

READING THE GROUND

What the reading found where you stand

Under your feet
The nearest water line
The boundary
The rain that falls here

Not finished

  • Three sample lands so far. It does not yet run on a parcel you draw.
  • A phone's position drifts by 5 to 25 m, more under trees or in a steep valley. A position looser than 25 m is set aside, and the page says so.
  • A water line marks where the ground gathers rain. Whether a stream runs there today takes a visit. A screening, not a survey: confirm on the ground before you build, dig or plant.
