Mapping of agricultural areas

By means of characteristic spectral information land use can be classified on different scales. This way one can obtain an over-view on the land allocation of a big area, can extract field boundaries, can observe the canopies and see the spatial distribution of crops.

Example 1

Fig. 1: Vegetation cover in winter in a water protection area

Important for nitrogen balancing but rarely available as contiguous information is the distribution of vegetation on agricultural fields during the winter months. This information can be provided via specific analyses of satellite imagery acquired during the winter months.

Example 2

Fig. 2: Satellite image (false colors) with large-scale agricultural classification (spatial resolution 30×30 m)

Large-scale classification gives on overview over the structures of whole regions. Winter and summer crops can be separated with a very high accuracy. The derivation of crop cycles is also possible.
