Map Products



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 which is a proxy for fresh biomass.

The ESVI can be transformed in zoning maps and used for decision making in precision farming, for crop insurance or disaster management.

The map product can be delivered on short notice 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 pseudo-natural color coding.

It is the ideal map product for farm managers, crop insurance underwriters and investors to follow up the growing processes in farmland and any kind of visual monitoring.

Due to the constant quality of SAR images and a complete time-series you can expect best result from time-series analysis with geo-statistical methods.

Crop Type Classification

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) shows the humitidy in plants and top-soil.

SAR sensors measure structure and humidity of the surface which represents naturally plant moisture.

It was calibrated against optical NDWI and shows high correlation.

The scale ranges from 0-150. The map product was tested in various regions.

It is useful for drought monitoring and irrigation schemes.
