Summary:<\/SPAN><\/P>

<\/P>

Water extent map produced using Copernicus Sentinel-1 Synthetic Aperture Radar (SAR). Potential flooding in the product is determined by comparing images before (10/12/2018) and after (4/22/2019) the flooding occurred.<\/SPAN><\/P>

<\/P>

Suggested Use:<\/SPAN><\/P>

<\/P>

Red pixels are anomalous water, or potentially flooded areas. These flooded areas are normally dry land. This product is best used with a layer or background map with known water that is prevalent throughout the year to determine where the flooding is occurring.<\/SPAN><\/P>
