Old maps, lined up

Import a scan of a plat map or county atlas and pin a few crossroads. It sits right on top of today’s map, with a fade slider.

LiDAR and satellite

Bare-earth LiDAR shows cellar holes, old roads and building pads the satellite can’t.

Sites and visits

Outline a field or yard. Finds inside it belong to it, and each trip is a visit with your time and path.

Public land

See federal, state and county land, and who manages it.
