Creating spectral indices NDVI NDBI NDWI NDMI in ArcGIS pro and water body extraction technique

This video is about creating different indices for image targeting. We can't predict many objects through our naked eye. The same object can reflect different numbers of spectrum in different conditions. For example, an object under direct sun and an object under shade may reflect different spectrum value. Therefore, it will hard detect the same object in different conditions. But the ratio of bands value will same for each object. And These indices are different bands ratios that will help us to detect an object easily.Here with image indices, I also shown how to extract object after indices which we can also call as image extraction technique. Here we extracted water body after NDWI technique.
