Towards Large-Scale TreeQSM Analysis: Overcoming Computational Bottlenecks

Last update: 2026-08-26 Working with high density point clouds of trees you quickly realize that you want to use quantitative structure models (QSM) to extract higher dimensional individual tree information from your 3D data. Basically there is no other technique to really describe the internal structural information in fully developed 3D point clouds of tree objects. Deep learning networks can...

Summer `26 Park3D flight campaign finished

Summer Campaign 2026 – SPSG Parks, Potsdam The summer flight campaign of 2026 has now come to an end. This week we completed the final acquisitions over Pfingstberg and Ruinenberg, concluding eight consecutive days of airborne data collection across the historic park landscapes of the SPSG in Potsdam. In total, approximately 800 ha were surveyed, acquiring leaf-on DJI L2 LiDAR...

Leaf-Off Flight Campaign in Park3D in`26

In march 2026, we began acquiring leaf-off data over all SPSG park areas in Potsdam as part of the Park3D project. This effort was primarily motivated by the improved potential for precise tree crown segmentation under leaf-off conditions. A key challenge in deciduous tree crown segmentation is that it is often not possible to directly verify whether a segmented...

Affiliation Change to FU Berlin

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 is also heavily impacted by...

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...

PD Dr. S. Hese on a temporary Professorship @Martin-Luther- University Halle-Wittenberg

Since first of April I am working on a temporary Professorship position @Martin-Luther-University Halle-Wittenberg leading the section “Digital Geography” at the Institute of Geoscience and Geography. At Friedrich-Schiller-University Jena I am right now on a leave and will likely be back for the MSc Geoinformatics courses in Summer 2021 @FSU Jena. This has no direct impact on my research projects...

UAV Flights in May 2020 over Hainich NP

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 flights (6 with the P4R...

Phantom 4 Multispectral (RTK)

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 be a game changer in...
