SpeleoMap

SpeleoMap turns an iPhone with LiDAR into a cave survey tool: survey lines, stations, splays, scans, photos and 3D maps, all made underground with no internet.

This channel has the learning videos: how to set up, survey a cave, scan a passage, use a laser meter or thermal camera, and export to Survex, Therion and PDF. Short how-tos for each feature, plus trips that show it working in real caves.

Cave survey, cartography and conservation, leaving no tape behind.
