In May 2018, our large MD4-1000 multicopter was used in East Germany. The main idea of this research study which was mainly developed by PhD student Christin Carl is to show the real measured invasiveness potential of black locust trees by using an UAS. Thereby, this study is a first step to create a tree invasiveness analyzing method for R. pseudoacacia. This approach, could be the basis to create a data base to appraise the real development and ecosystem changes basing on R. pseudoacacia and further non-native and native species. Overall we have collected over 120 Gigabyte of RGB and multispectral image data in 2 days. For our new pilot Pia it was the first flight campaign in the field. She did a very good job.
