How to Calculate NDVI using ArcGIS || Normalized Difference Vegetation Index
Показать описание
The normalized difference vegetation index (NDVI), which is derived from remote-sensing (satellite) data, is closely linked to drought conditions. To determine the density of green on a patch of land, the distinct colors (wavelengths) of visible and near-infrared sunlight reflected by the plants are observed.
The NDVI index detects and quantifies the presence of live green vegetation using this reflected light in the visible and near-infrared bands. Put simply, NDVI is an indicator of the vegetation greenness —the density and health—of each pixel in a satellite image.
