Flooding Extent Mapping for Synthetic Aperture Radar Time Series Using River Gauge Observations
Publikacja
- IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing - Rok 2020
The flooding extent area in a river valley is related to river gauge observations such as discharge and water elevations. The higher the water elevations, or discharge, the larger the flooding area. Flooding extent maps are often derived from synthetic aperture radar (SAR) images using thresholding methods. The thresholding methods vary in complexity and number of required parameters. We proposed a simple thresholding method that...

Floodplain inundation Mapping using SAR Scattering Coefficient Thresholding and Observed Discharge Data
Publikacja
- Rok 2019
Inundation area time series are important for wetlands monitoring and hydrological model validation. This study is conducted in Biebrza floodplain, which is a natural wetland with complex inundation generation processes. In order to map 2014-2018 series of inundation in the floodplain we test our automatic thresholding method on Sentinel 1 data. The threshold value is optimized using correlation of the inundation area with observed...
