Abstract:Water body detection is a process in environmental monitoring, resource management, and for disaster management applications. The previous work report highlights the increasing importance of precise water body detection in the scenario of climate change, for effective global water dynamics for making this technology vital for sustainable development and environmental conservation. This work presents the use of spectral features of multispectral imagery, for identifying and mapping various a quatic objects with increased accuracy. This work computes different water indices, such as the Normalized Difference Water Index (NDWI), Modified NDWI (MNDWI), and Water Ratio Index (WRI), to detect water body efficiently. Analysis of experimental results show that WRI provides the highest accuracy in delineating water bodies, followed by MNDWI and NDWI.
