Aerial photos flown for the state of Connecticut, from CT ECO at UConn. 1934 is the oldest statewide set: black and white, stitched from thousands of prints.
Bare earth
In 2023 a plane swept Connecticut with lasers. Some of the beams slipped between the leaves and hit the ground, so this map shows the land with every tree and building taken away.
Zoom into any woods and look for thin straight lines: stone walls from farms that were given up a century ago. Drag the handle to compare with the photo.
