Mapping of Flood Areas Using Landsat with Google Earth Engine Cloud Platform

The Earth Observation (EO) domain can provide valuable information products that significantly reduce the cost of mapping flood extent and improve accuracy monitoring systems. In this study, Landsat 5, 7, 8 were utilized to map inundation areas. Google Engine (GEE) was used implement Flood Mapping Algorithm (FMA) process data. FMA relies on developing a “data cube”, which is spatially overlapped pixels imagery captured over period time. This data cube identify temporary permanent water bodies using Modified Normalized Difference Water Index (MNDWI) site-specific elevation land use results assessed by calculating confusion matrix for nine events spread globe. had high true positive ranging from 71–90% overall in range 74–89%. short, observations GEE be as rapid robust hindsight tool areas, training AI models, enhancing existing efforts towards mitigation, monitoring, management.
