Water Mapping and Change Detection Using Time Series Derived from the Continuous Monitoring of Land Disturbance Algorithm
This provides a tool for environmental management and conservation by enabling accurate water mapping and change detection, though it appears incremental as it applies an existing algorithm to a new application.
The paper tackled the problem of monitoring water bodies by applying the Continuous Monitoring of Land Disturbance (COLD) algorithm to estimate water frequency and track pixel-level trends over time, finding that it reliably delineates water bodies and evaluates changes after disturbances.
Given the growing environmental challenges, accurate monitoring and prediction of changes in water bodies are essential for sustainable management and conservation. The Continuous Monitoring of Land Disturbance (COLD) algorithm provides a valuable tool for real-time analysis of land changes, such as deforestation, urban expansion, agricultural activities, and natural disasters. This capability enables timely interventions and more informed decision-making. This paper assesses the effectiveness of the algorithm to estimate water bodies and track pixel-level water trends over time. Our findings indicate that COLD-derived data can reliably estimate estimate water frequency during stable periods and delineate water bodies. Furthermore, it enables the evaluation of trends in water areas after disturbances, allowing for the determination of whether water frequency increases, decreases, or remains constant.
