Farmers may apply
for subsidies for certain crops from the Ministry of Agriculture.
The subsidies differ from one harvest to the next and before granting
the subsidies the Ministry checks to see, among other things, whether
the crops for which the applications are made have really been planted.
To differentiate the various crops you need images corresponding
to the different seasons. The
identification of different crops is done using aerial photographs
and imagery taken by optical satellite sensors.
In our region the Earth is often hidden by clouds. Consequently,
we see only white spots on the satellite images. It is thus impossible
to identify the crops on images that include clouds.
on the other hand, can look through clouds. So, they can probably
offer a solution, although high-level technical knowledge is required
to interpret them, and for best results they should be interpreted
by specialists. For the time being we are examining to what extent
radar images might be of help for crop identification work and other
applications, such as monitoring growth.
