TopoDroid - Cave Surveying with Android

IMPORTANT: The version on Google Play is old and will not be updated. Current version on: https://marcocorvi.altervista.org/caving/speleoapps/speleoapks/TopoDroidApks.html

TopoDroid helps you to take survey 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 a surveying trip. In this way by the time you finish it a working map is almost ready.

TopoDroid is designed to work *ONLY* with DistoX DistoX2 SAP5 and BRIC4. The survey data can be also entered by hand. TopoDroid supports DistoX calibration and other advanced DistoX features.

NOTE. DistoX is not a Leica product and TopoDroid does not work with any Leica Disto.

TopoDroid handles one survey session at a time. It is not a cave survey project manager. For that purpose there are many good PC programs and TopoDroid exports survey data in several cave program formats (among them: therion compass visualtopo walls survex) as well as dxf csv kml trackfile shapefile. Sketches can be exported as therion csurvey dxf svg shapefile and png image.
