To close those gaps, this study proposed a Google Earth Engine application for surface water extent mapping. The application, which will be referred to as MultiRS Flood Mapper hereafter, is compatible with the three most used RS image sources in water extent mapping applications, namely, Sentinel...
Policy Formulation and Implementation:The empirical foundation for formulating evidence-based policies lies in accurate flood susceptibility mapping. By shaping Land Use planning and zoning laws and environmental protection, these policies play a crucial role. By integrating data, urban development can be ...

The overall accuracies were higher than 90%, confirming the applicability of the Otsu automatic thresholding method in flood mapping. The automatic approach is efficient in rapid fold mapping across complex landscapes. 展开 关键词: Sentinel-1 Otsu Flood Aqqala Google Earth Engine ...
A simple approach to water mapping is to compute indices like the normalised difference water index (NDWI)24 which exploits the difference in absorption of light by water bodies between the green and the near infrared part of the electromagnetic spectrum. However, this method can perform poorly ...
Thus, in this paper, we develop the Residual Wave Vision U-Net (WVResU-Net), a deep learning segmentation architecture that utilizes advanced Vision Multi-Layer Perceptrons (MLPs) and ResU-Net for accurate and reliable flood mapping using Sentinel-1 SAR’s dual polarization data. Results showed...
Google Earth EngineNUMERICAL-MODELWATERDECADEThe Earth Observation (EO) domain can provide valuable information products that can significantly reduce the cost of mapping flood extent and improve the accuracy of mapping and monitoring systems. In this study, Landsat 5, 7, and 8 were utilized to ...
Comprehensive flood risk assessment is often constrained by a lack of appropriate data in high-altitude watersheds, particularly in developing countries like Nepal, where institutional capacities are limited for mapping and monitoring flood-prone communities. This study, one of the first of its kind,...
High spatial resolution satellite data have been effectively applied in water and wetland mapping and change analysis [50,51,52,53,54]. Sentinel satellites have demonstrated enhanced capacities in the monitoring of changing water and wetland environments, in recent years [55,56,57,58,59,60]. ...
Over these regions, mapping floodwater in an unsupervised way at Sentinel-1 GRD IW resolution (~20 × 22 m) is considered a really challenging task [45]. One of the future improvements of the FLOMPY toolbox will be the exploitation of interferometric coherence information in order to ...
