June 4, 2018 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 believe, that approx. 0.7 –... Categories Agriculture/Quadrocopter
March 21, 2018 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 the neighborhood of the tree...

January 31, 2018 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 WGS84 georeferenziert. Insgesamt wurden Daten... Categories Archaeology/Phantom/Point Clouds/Quadrocopter

November 14, 2017 Absolut Accuracy of the Phantom 4 Pro Ortho Mosaic Some results from DGPS point measurements with a Stonex S9III GNSS DGPS receiver indicate an offset of 1.5-3 m to the Phantom 4 Pro ortho mosaic images. The relative accuracy is however much better. The Phantom 4 Pro derived ortho mosaic (without reference points) has a standard deviation of 0.31 to 0.36 m. When comparing the overall positional accuracy of... Categories Agisoft/Phantom

September 26, 2017 “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 – the only problem: you kind... Categories Archaeology/Quadrocopter/Software/Workflow
