The satellite imagery is a Sentinel-1 Ground Range Detection C-SAR image from July 2nd, 2021, taken over the Sudd Wetland located in South Sudan. The image shows the 'VV' backscatter values, which correlate to vertical transmission and vertical reception from the C-SAR instrument and are used to classify wetland inundation extent. Low 'VV' values (blue) represent areas covered by open waters & inundated land areas and high 'VV' values (yellow) represent dry land areas.

An NDWI waterbody mask derived from Landsat-8 OLI cloud-masked imagery from March-May 2019-2021 is shown in blue at 10-meter resolution over Mexico, Belize, and Guatemala. The ALOS-PALSAR-2 fine-beam L-band false color composite includes Refined Lee speckle filtered HV, HH, HH/HV bands. Darker and brighter green hues represent to low and high backscatter, respectively. Differentiating between open water, like the Hondo River, from vegetated inundation is important when distinguishing inundation by land cove
