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 […]

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 […]

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

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 & […]

Erste urbane Copter Befliegung über Jena

In Kooperation mit der Abteilung Geoinformation (Leitung Dr. Markus Meinhardt) der Stadtverwaltung Jena  ( Dezernat III – Stadtentwicklung & Umwelt, Fachdienst Stadtumbau & Infrastruktur) wurde erstmalig durch den Lehrstuhl für Fernerkundung mit einem Quadrocopter eine städtische Flächenbefliegung durchgeführt. Ziel ist hier die Ableitung georeferenzierter  Ortho-Bildmosaike (sogenannte “True Ortho Bilder”), ein Gebäudehöhenmodel und ein texturiertes 3D Fassadenmodel. […]

Intra field growth variability

From a P4Pro test flight for agricultural within crop area variability analysis close to Erfurt for a agricultural application / cooperation.  This flight campaign covered a 700×700 sqm area from 100m altitude (85/85 configuration in DJI GS Pro). With the standard battery the P4Pro had 30% battery power left at landing – so overall I […]

Hotspot Effects in Micro Copter Data

A shot from last year vegetation point cloud mapping in Brandenburg. Strong Hotspot-Effect visible with easily visible shadow projection of the quadrocopter shape on the tree crown texture. Nice example of this direct back-reflection effect on vegetation (crown surface in this example), although you can also clearly see the same effect on the grassland vegetation in […]

Punktwolkenmodelle für die Archäologie

Die unterschiedlichen Datensätze der Befliegungen für die Grabungen auf dem Alten Gleisberg und bei Kuckenburg in 2017 sind nun vollständig an das Seminar für Ur- und Frühgeschichtliche Archäologie übergeben worden. Die abgeleiteten Datenlayer umfassen jeweils Punktwolkenmodelle im LAS Format, DSM (Digitales Oberflächenmodell ohne Normalisierung) und jeweils das Orthomosaik mit Georeferenzierung von der Befliegung. Alle Daten wurden nach UTM32 […]

“DJI GS Pro” – Ground Station Testing

Some tests using the DJI GS Pro (Ground Station) software for automatic flight programming with the Phantom 4 Pro. New flight campaign at the Kuckenburg spot (Sachsen-Anhalt) finished with two different flight altitudes using DJI GS Pro – mapping the open archaeological excavation site of medieval church now in September 2017. This worked flawless – […]
