For CNN (Convolutional Neural Network) training and calibration we started working in the historical park areas (Park Glienicke) in the South-West of Berlin. These forest stands are dominated by very dry soil conditions and the beech trees suffer here as much as in some regions of the Hainich National Park area. There is however more […]
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 […]
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 […]
Update 4.4.2020 Cartogram reprojection using county based shapes and recent data from RKI. These maps are quantile classified – not equal interval classified. This clearly changes somehow the color distribution since the local maxima are not visible anymore. Overall this visualization is graphically very appealing – however it needs more attention for the legend 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. You can read the PDF version here: http://www.lichtgedanken.uni-jena.de/magazinmedia/Aktuelle+Ausgabe/Lichtgedanken+07+%E2%80%93+Zukunft+ohne+Wachstum-download-1.pdf or the HTML version here: https://www.lichtgedanken.uni-jena.de/Ausgabe_07_Buchen_in_Not-path-140,5.html There will be also an english language version soon.
As a side product of our Hainich NP forest monitoring program in summer/autumn 2019 we also mapped maize fields west of the Hainich National Park region. These fields are heavily damaged by wild boar regularly and the change is detectable already after days. The RTK Phantom that we used in September for the maize fields […]
Cold air and short illumination time frame – thats what dominated the flight campaign at the 31st of October 2019 in the Hainich National Park. Originally flights on all test sites were planned but this was hardly possible in this short time frame without enough light. So I covered the Huss area and the West […]
