Radar Indices

This service provides a radar vegetation index (RVI) image for your specified area of interest.

RVI is a measure of vegetation abundance, and can therefore be used through a crop or pasture growing season to assess the relative amounts of vegetation present. Similar to how Normalized Difference Vegetation Index (NDVI) is used, but measuring abundance rather than vigour/greenness, RVI images have the benefit of all-weather validity. Given an area of interest, the algorithm is run using Sentinel-1 to return the indices from the start date to the optional end date. Imagery is output as a GeoTIFF for each set of input VH and VV files for a specific date, with a single band representing the calculated index. Pixel values are typically on a normalised scale (0 to 4). All GeoTIFF files are provided at native resolution of the inputs.
