Standardized Vegetation Index (SVI) is an index of the relative vegetation condition compared to the years being analyzed based on NDVI.
Here's a map of SVI in Tanzania between 2000 and 2021.
Normalized Diffence Vegetation Index (NDVI) is a common metrics that is easy to calculate {NDVI = (NIR - RED)/(NIR + RED)}from remote sensing data and is commonly used as a proxy for knowing vegetation condition. The resulting values range from -1 to 1 #30DaysOfGIS
