Summary:

Scientists at NASA's Marshall Space Flight Center created these water extents on September 29, 2022 using the RADARSAT-2 Synthetic Aperture Radar (SAR) instrument. These images can be used to see where water is located at the time of the satellite overpass. This product shows all water detected and differentiates between normal water areas and some flooded areas. It's important to note that all flooded areas may not be captured by these images. To determine where additional flooding may have occurred, combine this layer with other data sets.

This service contains modified RADARSAT-2 data, collected through Hazards Data Distribution System (HDDS)-USGS; post-processing and data product development performed by NASA Marshall Space Flight Center. The following copyright notice must be conspicuously displayed alongside the Product, or any portion thereof: “RADARSAT-2 Data and Products © Maxar Technologies Ltd.

Suggested Use:

This product shows water that is detected by the sensor with different colors indicating different land cover/land use classifications that appear to have water and are potentially flooded.

• Blue: Known Water

• Red: Anomalous Water

• Green: Flooded Wetlands

• Brown: Flooded Croplands

• Purple: Potentially Flooded Developed Areas (Low Confidence)

Caveats: the majority of developed areas were filtered out due the capabilities of the sensor to detect urban flooding. As a result, these images may not detect all flooding and some potentially flooded developed areas could be inaccurate.
