The area of the rockfall event above vineyards within a nature protection zone

Due to a recent rockfall event and in order to analyze the landscape conditions within this area did we conduct a UAV Lidar mapping campaign in Thüngersheim, close to Würzburg. The main aim was to retrieve necessary environmental information about this specific area in very high spatial resolution to understand the causes of this rockfall and the potential future developments. In collaboration with soil scientists from the University of Würzburg our UAV data does contribute to the rockfall risk estimation.

We covered the larger area with large research UAVs carrying a Lidar sensor that allows to retrieve ground level information as well as the height of the vegetation.

Further information will be acquired in the next days in order to gain more insights into the landscape conditions.

Actual surface properties without vegetation cover is retrieved. The detailed soil properties can be clearly distinguished.
