Use of targeted catch crops is one of
the nitrogen reduction initiatives intended to compensate for relaxation of the
Food and Agricultural Package, which gave Danish farmers the option to increase
the use of fertilizer on their fields. Targeted catch crops help ensure that
there is no deterioration of our coastal waters and groundwater.
The Danish Agrifish Agency is
responsible for determining whether registered catch crop fields are
established at the right time and with the intended effect. Freely available Sentinel-1 data is suitable for this purpose because data collection
takes place using Synthetic Aperture Radar (SAR), which is unaffected by the
often dense cloud cover over Denmark. Among other things, the Sentinel-1
satellites detect changes in surface structure, e.g. the gradual transition
from bare soil to vegetation.
We currently envision a project in which
perhaps a master student with experience with GIS and handling large amounts
of geodata will detect changes in the radar signal at field level and possibly
display results using a web service on a regular basis. Access to these results
will play a major role in the planning of physical inspection visits.
In this project you can get the opportunity
to focus on satellite data and GIS, and work with machine learning applied to
geodata, which are skills increasingly in demand.
