GSD Calculator – don’t leave the precision of your drone surveys to chance

Use our simple GSD Calculator to forecast the precision in your photogrammetric reconstructions.

If you’re planning to use drone technology and photogrammetry software as a source to conduct horizontal and vertical measurements to land and objects, it’s critical that you understand the effect that the equipment choice and the distance from the subject both have on the ground sample distance (GSD) and subsequently, the point-to-point precision of measurements made to your photogrammetric reconstructions.
