emirhartato/NDVI-Change
This script is designed to compare Normal Difference Vegetation Index (NDVI) of two raster images (EO-1, multispectral) in Bali with different time (2011 and 2014) using GDAL and NumPy. Each raster is converted into set of array then NDVI is calculated (NIR - RED / NIR + RED). After that, NDVI difference between both image is calculated by subtraction and result is converted to absolute value. The result is a new raster file which contains NDVI value difference to identify vegetation changes where higher value (lighter pixel) indicating massive vegetation changes over three years period.
