Service Description: Dates of Images:
4/30/2024, 5/7/2024, 5/12/2024
Date of Next Image:
Varies by region, typically 12 days since previous pass.
Summary:
The Alaska Satellite Facility has developed surface water extent products of the Sentinel-1A/B 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 does not differentiate between normal water and flood water. To determine where flooding may have occurred, combine this layer with a reference water layer.
The water extent difference maps shown here were created by subtracting the water extent of the first date from the water extent of the second date to show what changes, if any, occurred in the water extent.
Suggested Use:
Water extent difference:
Light Blue: Water Present in the Second Date Only
Dark Blue: Water Present in Both Dates
Orange: Water Present in the First Date Only
Satellite/Sensor:
Synthetic Aperture Radar on European Space Agency's (ESA) Copernicus Sentinel-1A satellite
Resolution:
30 meters
