For those that have been wondering where I am right now working – I changed to another interims professorship – this time at Free University Berlin at the Institute of Geographical Sciences / Remote Sensing and Geoinformatics Group. Perfect place to work on the drought induced beech mortaility analysis project since the south-west of Berlin […]
Some results from our stand gap analysis for July 2018 , July 2019 and July 2020 are now finished. Some figures below. There is a strong change process in the northern part of the Hainich landscape region in progress – likely dominated by forest management activities . removing the dying beech trees from the stand. […]
UPDATE 12.12.2020: First classification within the SPSG park regions of four different damage categories was done in December 2020 using the TensorFlow CNN implementation. The first test area is the landscape park area “Glienicke” in the south-west of Berlin. The area shows a severe degradation of beech trees on some locations and is as of […]
The first UAV flights of the vegetation period took place this year at the 28th of May. We covered the test areas East of Berka v.d.H. (Burgberg & Eichenberg) and parts of the Zimmerberg area. We also did flights over the region of Hegeberg in the North-East of the national park. Overall we did 14 […]
April 2020: Planning for the May flight campaign is in full swing. The test sites will be extended in 2020. Figure below: overview of the 2019 test areas from a presentation at DLR Bonn in 2019. We will extend this to areas in the northern Hainich (Dachsberg) and also covering the private forested areas in […]
DJI did it again – the leading manufacturer of compact “of the shelve” drone solutions modified the Phantom 4 RTK and added a fully integrated multispectral camera. Those that are working with these (micro)multispectral camera systems on small UAV platforms couldnt really believe this news. DJI modified the Phantom 4 RTK (that turned out to […]
A short article about our work in the Hainich National Park area on the beech degradation analysis appeared in the Journal of the Friedrich-Schiller-University Jena “Lichtgedanken” in Edition 7.

Since July we have been very active covering the forest change in the Hainich National park region using the Phantom 4 Pro copter and the new Phantom 4 RTK (P4R). A project in cooperation with the Hainich national park administration, ThüringenForst and DLR Institute for Data Science Jena. First flights over 5 test areas were […]
