A New Spectral Index for Mapping Water Surfaces in Urban Contexts

A New Spectral Index for Mapping Water Surfaces in Urban Contexts

This article proposes a modification of the modified normalized difference water index (MNDWI) called rescaled water index (RWI), aiming to enhance the delineation and performance of water body mapping in urban contexts. To evaluate the proposed index, we compare its performance in mapping water sur...
