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 […]

CIR Airphoto Classification and Planning for 2020

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 […]

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 […]

SARS-CoV-2 Cartograms

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 […]

Buchen in Not

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.

RTK Precision Mapping of Wild Boar Maize Field Damages

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 […]

Late October ’19 Flight Campaign in the Hainich NP

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 […]

MDR Doku with EO contribution

A nice MDR Wissen Doku has been published with contributions from our Hainich National Park beech declining mapping project. We explain some of the concepts how we use copter technology to analyze Sentinel-2 satellite data of the forest decline in the Hainich forest region. https://www.mdr.de/video/mdr-videos/d/video-338706.html

Wild Boar Damage Mapping in Maize Fields

As part of the disturbance mapping project we captured 300 ha of maize field area to investigate wild boar damages in the direct neighborhood of the Hainich National park area – a cooperation of the Earth observation department of FSU Jena, DLR Jena and NLPV Hainich. Wild boar damage mapping in agricultural areas – the […]
