S-09 · Air and remote sensing
For farms and research stations, we produce maps of biomass, nitrogen supply and water stress. On request, we calibrate the aerial data against soil and plant samples.
How we carry out this service.
01We agree crops, growth stages and fertiliser dates with the farm. This determines the flight plan, usually two to three flights in cereals between tillering and ear emergence. Multispectral surveys are carried out through partners in light that is as even as possible and with calibration against a reflectance panel.
02From the spectral data we calculate vegetation indices and calibrate them against plant cuttings and soil samples at representative points. These samples are analysed for nitrogen and dry matter in accredited partner laboratories. Only this calibration allows reliable statements on the nitrogen uptake of the crop instead of purely relative values.
03We translate the results into application zones with target rates and export them as Shapefile or ISO-XML for your terminal. After damage from hail, wildlife or drought, we fly as soon as possible after the event and document capture time, georeferencing and processing so that insurers can verify the report.
Operating in Germany and the EU
e.g. 200 to 2,000 ha
Agricultural cooperative, Germany
Survey flights before the fertiliser dates, calibrated with plant and soil samples. Multispectral data for nitrogen maps are collected through partners, and prescription maps are delivered as Shapefile or ISO-XML.
e.g. 50 to 500 ha
Farm, Rhön and eastern Hesse
Documentation of hail damage shortly after the storm, with capture time and georeferencing. The report can serve the insurer as a basis for settling the claim.
The examples show typical procedures for this service.
It shows differences within the crop that cannot be seen from the field edge. Fertiliser and water can then be applied as needed, and damage can be documented with area and date.
As evidence, yes, provided that capture time, georeferencing and processing are documented. The insurer decides on the claim itself, often with its own loss adjuster.
For nitrogen fertilisation in cereals, usually two to three flights before the application dates. For damage documentation, one flight shortly after the event is enough.
Tell us the area, location and time frame. You will receive an assessment within two working days.
