Mapping and analysis of the flooded areas using NDWI

There is a single-channel and multi-channel approach to classification. Access Code that uses multiple channels, NDVI (Normalized Difference Vegetation Index) and "water" index NDWI (Normalized Difference Water Index). NDWI index is similar as the NDVI-ROM, and the function is visible green and close infrared radiation. This formulation index enabled: (1) maximizing the reflection of green wavelengths from the water surface, (2) minimizing the low-reflectance near-IR wavelengths with bodies of water, and (3) use of the advantages of high-reflective near-IR wavelengths with a surface covered with vegetation and the soil.
