Using Images of Continental Water Surface Elevations From Upcoming Satellite Mission

The proposed Surface Water and Ocean Topography (SWOT) satellite mission, which is under development at NASA, the Centre National d'Etudes Spatiales (CNES), and the Canadian Space Agency, is currently planned for launch in 2020. SWOT would provide maps of water surface elevation globally, observing rivers wider than about 50–100 meters and other water bodies with dimensions (widths and lengths) greater than 250 meters.
