Potoška planina Scree – Mission #2

The goal was to observe scree that has accumulated on the slopes just outside the village of Potoki. Two drone flights, one in 2014 and the other in 2015, were performed to collect the data needed to compute displacement vectors and register the land mass movement.

We also used this project as a live-case study of terrestrial laser scanner. The main purpose was to see which method performs better, aerial or terrestrial. We were thrilled to learn that a drone-based method paired with 3Dsurvey software proved superior. The results showed absence of blind spot, an observation time four times faster and more accurate calculations of a textured point cloud, an orthophoto mosaic and a 3D model.
