New UAV regulations in place and active

The new UAV regulations are now active in Germany! For commerical and research flights things are more simple now for copters below 2kg. There is now a general allowance in place for the full federal region of Germany for UAVs below 2 kg (with the restricted regions as listed in the regulations). For copters with […]

Speeding up Agisoft Photoscan

For some of the copter data processing folks Agisoft Photoscan turns out to be the most important tool to calculate point clouds, orthoimages and nadir data mosaics. Problem: very long processing times with dense point cloud calculations with high or ultra-high settings (full resolution image matching with SfM (Structure from Motion) algorithms). Some nice net […]

MicroSD cards and standards …

There is a lot of confusion about the speed of MicroSD cards these days and various standards exist. Overall its easy to buy yourself into the wrong card type and for copter data acquisitions with the P4Pro the card speed is essential. So here we go: UHS-I and UHS-II (Ultra High Speed Classes): UHS-II is […]

Using DroneDeploy and the POI mode for automatic point cloud mapping

Using DroneDeploy and the POI mode of DJI. Have been doing some leaf-off flights now in March on one of my favorite sites for complex tree crown point cloud mapping. To add to the leaf-on data from last autumn. Fig.: Leaf-Off point cloud with combined height color coding and reflectance color coding. This time I also […]

“Drohnenverordnung” in the Federal Council

Regulations to fly copters  the “Drohnenverordnung” went through the Federal Council – the 100m regulation will be redone. Overall good news for those of us who fly for research or commerical projects. The ascent permission for copters below 2kg/5kg  was skipped. This will make it much easier to fly within legal regulations. https://www.heise.de/newsticker/meldung/Drohnenverordnung-Bundesrat-erhoert-die-Modellflieger-3649944.html http://www.bundesrat.de/SharedDocs/drucksachen/2017/0001-0100/39-1-17.p%20df?__blob=publicationFile&v=1 http://www.bundesrat.de/DE/plenum/plenum-kompakt/17/954/079.html?view=main%5BDrucken%5D

NoFly Zones

For flight planning usually some information about the restricted zones is important. Some nice net finds: Flugbeschränkungsgebiete/NoFly Zones nice map is avail here http://maps.openaip.net A map with the national parc areas in Germany is available here: http://www.geodienste.bfn.de/schutzgebiete/#?centerX=3799285.483?centerY=5822015.931?scale=5000000?layers=524    

Phantom 4 Pro – lens flare issues

Some more tests with the Phantom 4 Pro: one major “issue” with this system for stills / photography is imo clearly the flare sensitivity of the lens/sensor combination. The into the sun shots just capture a lot of flare and the sun star is very much Samyang 14mm like. This is an issue and it […]
