S-01 · Air and remote sensing
We survey forest and agricultural land with our own drones and our own remote pilots: the DJI Mavic 3 for aerial imagery and the DJI Mavic 3 Thermal for thermal imaging. Multispectral and LiDAR surveys are available on request through partners.
How we carry out this service.
01Before every deployment, our flight operations team at the Rhön field station checks the airspace, protected areas and obstacles and sets the flight lines in the planning software. Overlap, altitude and speed depend on the camera and the question. For orthomosaics we fly with high forward and side overlap so that canopies are captured without gaps.
02On the day of the flight, the remote pilots check the aircraft, camera and weather. For georeferencing, we lay out ground control points and survey them by GNSS. Additional check points that are not used in the calculation show the positional accuracy achieved, which we report in the quality report.
03Processing is carried out by our GIS team. The raw data are turned into orthomosaics in the ETRS89/UTM reference system. Every delivery undergoes a second check for data gaps, image errors and positional deviations before we hand it over to you digitally. Multispectral or LiDAR data from partners are checked and integrated using the same procedure.
Operating in Germany and the EU
e.g. 500 to 3,000 ha
Forest owners’ association, Rhön and eastern Hesse
Survey of the members’ land with the Mavic 3 as a basis for overview maps and damage mapping. Control points are surveyed by GNSS, and orthomosaics are delivered in the ETRS89/UTM reference system.
e.g. 100 to 1,000 ha of damaged area
Forest enterprise, Germany and Europe
Survey after a storm event to delineate the damaged areas. The map serves as a basis for salvage work and funding applications. Where required, we add LiDAR data for volume estimates through partners.
The examples show typical procedures for this service.
Yes, within the EU drone regulation and national air traffic rules. Protected areas, control zones and flights beyond visual line of sight require permits, which we obtain before the deployment.
That depends on flight altitude, image overlap, weather and terrain. We will tell you the time required for your area once the flight has been planned.
LiDAR measures structure: tree heights, crowns and the terrain beneath the stand. Multispectral imagery measures reflectance in several wavelengths and indicates vitality and stress. We offer both on request through partners.
Tell us the area, location and time frame. You will receive an assessment within two working days.
