Last Update: 14.5.2021 There was some confusion in the past on how to process the Phantom 4M Multispectral data to “reflectance” level. Here a short summary for Agisoft Metashape 1.7.2 with a 50% reflectance panel from Micasense (update: now its from SphereOptics). In general: 1. the P4M sun illu. sensor works for normalizing the within […]
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 […]
Die neue EU Drohnenverordnung ist in Kraft getreten. Sie gilt im Prinzip bereits seit 1.1.2021. Was hat sich geändert? Einiges! Nach der neuen Verordnung sind alle derzeit im Betrieb befindlichen Drohnen keine zertifizierten Drohnen. Hier hinkt die Industrie der Verordnung hinterher. Die Verordnung differenziert in der offenen Kategorie “OPEN” nach dem Grad der Gefährdung, der […]
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 […]
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 […]
