OpenEO
Sentinel-1 statistics
Description
This algorithm derives temporal statistics from the Sentinel-1 GRD collection for the selected spatial- and temporal extent of interest. In order to calibrate the SAR backscatter signal, sigma0-ellipsoid has been applied within this workflow.
Performance characteristics
The algorithm was evaluated for a spatial extent of 20x20km, for a temporal period of 3 months. The total cost for the performed evaluation was equal to 4 credits, thereby highlighting the efficiency of the underlying algorithm.
Examples
Below we show the derived minimum and maximum values for both VV and VH bands, calculated for the 20x20 km2 area of interest.
