In order to callibrate 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. + +![s1_stats](sentinel1.png) \ No newline at end of file
