Remote Sensing
Why does NDVI, NDBI, NDWI Ranges From -1 to 1?
The indices calculated from satellite imageries such as Normalized Difference Vegetation Index (NDVI), Normalized Difference Built Index (NDBI) and Normalized Difference Water Index (NDWI) have indices value ranges from -1
Remote Sensing
Vegetation Indices
Vegetation Indices has proved to have an extremely wide (and growing) range of applications. It is used to monitor vegetation conditions and therefore provide early warning on droughts and famines.

Maximum Value Composite Images (MVC’s): A solution for Cloudy Image to calculate NDVI
When the satellite views an area at any one time, a large part of the image may be cloud, which has a very low NDVI (approximately 0.002). This gives no
