Editorial interest 86/100 Selection signal · not a rating of the site

An interactive map estimates Vermont’s stone walls from lidar, with confidence bands, town-level counts, and a history of the walls.

Landing page captured for the 2026-10-28 issue.
For
Vermont history and landscape enthusiasts
Worth noticing
The map separates solid, dashed, and hidden walls by confidence; the highest-confidence band was 89% real on New Hampshire test ground.

Field notes

The model uses four directional hillshades plus slope and local relief from a one-meter lidar ground model. Its training set comes from volunteer tracings in 42 New Hampshire squares, with each square shown in eight rotations and flips. The page distinguishes its Vermont comparisons against hand-traced walls from a separate New Hampshire test, and explicitly notes that the map both misses real walls and draws some that are not there.
