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.Suggested Use:In this image, water appears in blue, vegetated areas in shades of green and urban areas in bright orange. It is recommended to use this product with ancillary information to derive flooded areas.Satellite/Sensor:Copernicus Sentinel-1 Synthetic Aperture Radar (SAR).Resolution:30 metersCredits:NASA/MSFC, ESA CopernicusEsri REST Endpoint:See URL section on the right side of page.WMS Endpoint:Data Download:https://maps.disasters.nasa.gov/download/gis_products/event_specific/2021/hurricane_ida/sentinel1/rgb/
