Lidarman Maps the Shapes Buried in Terrain

Field notes

Lidarman combines several terrain derivatives from bare-earth elevation models, then ranks contours according to whether they resemble rectangular or circular human-made features. The interface lets users compare composite, hillshade, slope, and red/blue local-relief views, with guidance for recognizing sunken paths, cellars, foundations, walls, and mounds. Search presets cover named US battlefields, while the page also describes a scriptable CLI and a present/past flicker comparator for checking a feature’s current position.
