FSU Jena wins the SPSG Park3D Project!

The FSU Jenacopter Labs team won the Park3D project proposal with SPSG in Potsdam. In 2025 and 2026 we will in detail analyze the vitality of the vegetation in the historical park regions Sanssouci and Babelsberg with various sensors: DJIs photogrammetric camera system P1 and the Lidar sensor L2 as well as with the MicaSense Multispectral camera system for calibrated...

3D point cloud of the 1000 years old Ivenacker Oack Trees

Its always a challenge to work on vegetation point cloud renderings with multi view image matching concepts. In complex 3-dimensional environments and for horizontal image capturing – using a drone is often just not possible. Here horizontal imaging can be an affordable alternative to TLS (Terrestrial Lidar Scanning) systems. Drawback of most OTS consumer electronics camera systems is the missing...

Stand Gap Analysis in the Hainich National Park between 2018 and 2020.

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. Our spatial analysis indicates that...

UPDATE 12.12.2020: Beech Tree Damage Analysis in the Historical Parks – South-West of Berlin

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 now not open for the...

The Hainich Flight Campaign

At the end of August 2018 a consortium was initiated by Dr. C. Thiel (DLR) to start a flight campaign within the Hainich national parc area in Thuringia (DLR Jena: Dr. C. Thiel, FSU Jena: Dr. S. Hese, University Göttingen (LS für Bioklimatologie, Prof. Dr. A. Knohl / Dipl.-Ing F. Tiedemann), national parc Hainich: Manfred Grossmann & Andreas Henkel).  The region is...
