ESVI shows the spatial variability of cropland over the season within one scale. The values range from 0 – 100 and correlate quite well with optical NDVI and other biomass indices.

SAR measures structure and humidity of cropland. The signal can be transformed in an index that represents fresh biomass.

In front season we detect soil preparation measures like ploughing or harrowing before crop starts growing.

The ESVI can be used for decision making in precision farming or crop monitoring for crop insurance or disaster management.

The map product can be delivered for single crop-types on field level or over all crop-types on regional level.

Color Composite

The color composite is purely derived from single date Sentinel-1 SAR data.

It gives a high contrast and shows different zones within single plots.

This map product is easy to perceive due to its natural color coding.

It is the ideal map product for farm managers, crop insurance underwriters and investors to understand what is going on the farms.

Crop Type Maps

Crop-type differentiation for crop-type groups indicates parcels of cropland.

This map product allows to aggregate the total cultivated area per crop-type and region.

The information is useful for market survey as well as for disaster management to prevent from food shortfall.


SWI (SAR water index)

The map product shows the moisture content in the vegetation and topsoil.

The data were tested against the NDWI and correlate very well with this optical index.

The product is suitable for large-scale drought monitoring. It reliably indicates a deficit in precipitation.

It is suitable for use in irrigation management.
