Introduction This paper describes improvements in the elevations provided by a 2D tide and surge model which are employed to height shorelines produced by processing SAR images from the ERS-1 and ERS-2 satellites. The resulting quasi-contours can be used to create a height map, or Digital Elevation Model (DEM) of the inter-tidal zone. Such maps are valuable tools in shoreline management plans [1] for civil engineering and marine conservation. The long term aim of monitoring
