1-meter resolution bare-earth digital elevation models (DEM) are available for the areas shown. The project was developed by NOAA’s Coastal Services Center and the NYS DEC to collect and deliver topographic elevation point data from LIDAR for areas of coastal New York. Data are intended for use in coastal management decision making, including applications related to projected sea level rise and the remapping of Coastal Erosion Hazard Areas.

The Discover GIS Data NY will take you to two different versions of the Coastal LiDAR DEM: a tidal water raster DEM and a hydroflattened raster DEM.  The hydroflattened DEM was produced from the tidal water raster DEM by replacing observed elevations of the tidal water surface with a mean high water surface derived from Vdatum (http://vdatum.noaa.gov/).
