This is the LIDAR intensity image of Weetamoo Woods in Tiverton, RI.
This shows the footprint of the LIDAR raw data file downloaded from the USGS. Houses are visible to the right, and a stream runs south from the swamp at the north. Below is the Fusion LDV showing a small farm which I knew to be there.
This area is to the bottom right of the intensity image. The whole ground surface DTM file was converted to ASCII and imported into Grass GIS. Here it is displayed in garishly colored 3D.
The houses along the road show up clearly to the upper right. Lafayette Road is a narrow depression running diagonally across the upper half of the area. It shows up better in my monitor, but I see two sets of walls.
The old farm is at waypoint 1458, and the other group of walls is visible as the blue dots just south of Lafayette Road, including waypoint 1296. There is supposed to be a way to enter GPS waypoints into these GIS projects, and to extract coordinates. That is another chapter in the "Dummies" book...
