CaveSurvey tries to aid data collection while surveying caves. It uses no paper and is simple and free. Measurements can be populated with the devices you already have: manually for analog instruments, via Bluetooth from laser distance meters or with the Android built-in sensors. One can also have notes, GPS locations, pictures, sketches etc. Data collected can be verified on site with simple 2D map and exported in Excel, AutoCAD, Therion, Google Earth, SVG and others for further processing. More details are available on our project website.
