Vegetation indices (VI) are measurements of plant activity on the terrestrial surface. NDVI (normalized difference vegetation index) is obtained from the spectral bands in the red and near infrared range. This index is a good measure of the amount and vigor of vegetation (photosynthetic activity), it is closely related to the type of vegetation, and climatic conditions. The NDVI time series show the trend of natural vegetation and crop development.
