Slano Blato landslide

Slano blato landslide is 1650m long, 250m wide with height differences of 380m. The objective was to monitor the changes in the land mass movement through several consecutive measurements. Ten drone flights at the height of 80m were needed to cover the whole area, mainly due to its size. Ground control points were measured using a classical terrestrial geodetic technique. We followed a traditional observation approach to assess the quality of photogrammetric measurements that were then used to define displacement vectors.
