TopoDroid - Cave surveying on Android
TopoDroid helps you to take surveying data and accurate sketches while you
are in the cave, so that you can detect errors in the data while you are still on the spot and correct them.
TopoDroid has many functions to help you get the most out of surveying trip. In this way, by the time you finish it a working map is almost ready.
TopoDroid is designed to work only with the DistoX. However, the survey data can be also entered manually. TopoDroid has DistoX calibration functions, as well as other advanced DistoX functions.
TopoDroid handles one survey session at a time. It is not a cave survey project manager. For that purpose many good PC programs, already exist, and TopoDroid exports survey data in several PC cave program formats (among them: therion, compass, visualtopo, walls, survex), as well as dxf, csv, kml, track-file. Sketches can be exported as therion, csurvey, dxf, svg, and png files.
