The SurfZone Digital Elevation Model (DEM) was produced in 2014 to model the coastal zone post the 2013/2014 UK winter storms. Using the best available LIDAR and near-shore multibeam SONAR bathymetry available at the time, it is the best currently available Digital Elevation Model (DEM) covering the inter-tidal zone produced by the Environment Agency.

The SurfZone DEM was produced by using a bespoke feathering technique to smooth the overlaps between LIDAR and Bathymetric surveys to produce a seamless surface. Small gaps between surveys were interpolated to produce a full coverage DEM of the near-shore. For all regions except Anglian Digital Terrain Models (DTM) derived from LIDAR were used. For the Anglian coastline a Digital Surface Models (DSM) were used.

All LIDAR data used in the production of the SurfZone DEM was surveyed by the Environment Agency. Bathymetry Data was supplied by the Environment Agency and the National Network of Regional Coastal Monitoring Programmes of England from the Channel Coastal Observatory (www.channelcoast.org) website.The National Network of Regional Coastal Monitoring Programmes of England comprises of 6 Regional Programmes.
