Generic Sentinel-2 Band Ratio Processor

This index results from the following equation: Index = (Band_A) / (Band_B). The default is to use Sentinel-2 Band 8 (Near Infrared) as Band_A and Band 4 (Red) as Band_B (for Sentinel-2 bands see https://earth.esa.int/web/sentinel/user-guides/sentinel-2-msi/resolution...). The default band values belong to the Ratio Vegetation Index (RVI). The RVI is a widely used vegetation index that indicates the amount of vegetation. The higher the value, the more vegetation. Low values show soil, ice, water etc. The user can choose every available band combination (see Sentinel-2 link). (Kriegler, F.J. et al., Proceedings of the Sixth International Symposium on Remote Sensing of Environment, p.97(1969))

The Ratio Index service is a parallel processing service based on ESA's Sentinel-2 Toolbox. The Service is called "S2_BandRatio"  and is to be found in the Explorer / Services tab of the Food Security TEP GUI.
