Vegetation Indices

This service provides 11 vegetation indices as images for your specified area of interest.

Vegetation indices provide metrics about vegetation properties. Given an area of interest, the algorithm is run using Sentinel-2 to return the indices from the start date to the optional end date. The indices produced are:

• Enhanced Vegetation Index (EVI),
• Green Vegetation Index (GVI),
• Leaf Area Index (LAI),
• Modified Triangular Vegetation Index - Improved (MTVII),
• Normalized Difference Vegetation Index (NDVI),
• Optimized Soil Adjusted Vegetation Index (OSAVI),
• Plant Senescence Reflectance Index (PSRI),
• Renormalized Difference Vegetation Index (RDVI),
• Red Edge Normalized Difference Vegetation Index (RENDVI) and
• Red Green Ratio Index (RGRI).
• Soil Adjusted Vegetation Index (SAVI).
• Normalized Difference Nitrogen Index (NDNI).

The imagery is output as a series of GeoTIFF files, each with a single band representing the calculated indices. Pixel values are typically on a normalised scale (-1 to 1), although a small number of indices have different potential ranges of values. All GeoTIFF files are provided at native resolution of the inputs.
