Editorial statement
The paper demonstrates how oceanographic parameters, like Sea Level Anomaly, surface currents and vorticity, from remote sensing are improved when SWOT (Surface Water Ocean Topography) data are included.

Short summary
The Surface Water and Ocean Topography (SWOT) mission provides unprecedented swath altimetry data. This study examines SWOT's impact on mapping systems, showing a moderate effect with the current nadir altimetry constellation and a stronger impact with a reduced one. Integrating SWOT with dynamic mapping techniques improves the resolution of satellite-derived products, offering promising solutions for studying and monitoring sea-level variability at finer scales.
