Sentinel 1 - RGB Flood MapThe Alaska Satellite Facility developed a false color Red, Green, Blue (RGB) composite image of the Sentinel-1A/B Synthetic Aperture Radar (SAR) instrument which assigns the co- and cross-polarization information to a channel in the RGB composite. When used to support a flooding event, areas in blue denotes water present at the time of the satellite overpass before or after the start of the flooding event.

Sentinel 1 - Water Extent MapThis product shows three areas: known reference water (blue), anomalous water identified outside the known reference water areas (red), and water detected in known wetlands or barren land (tan). This product can be used to perform a change analysis due to the flooding. \Satellite: Synthetic Aperture Radar on European Space Agency's (ESA) Copernicus Sentinel 1 A/B satellite; 30 m resolutionCredits: Copernicus Sentinel data (2019), processed by ESA, Alaska Satellite Facility, and NASA Marshal Space Flight Center. Landsat 8 Natural Color RGBAreas of water will appear blue, healthy green vegetation will appear as bright green, urban areas in various shades of magentas, clouds appear as white or bright blue, and bare soils being multicolor dependent on their makeup.
