Water indices are the topic of this video. At the end of the video, you'll be able to apply any water index to your images.
Accurate and frequent updates of surface water have been made possible by remote sensing technology. Index methods are mostly used for surface water estimation which separates the water from the background based on a threshold value. An index is generated by combining data from multiple spectral bands into a single value using Usually simple algebraic formulations.
in this video, not only do we show you the needed Preprocessing, but we also apply NDVI, NDWI, WRI, and AWEI (sh nsh) indices on Landsat 8 images in the ENVI software.
