Geophysical Data Center (NGDC) is addressing this need by assembling a gridded database that merges the US Geological Survey 3-arc-second DEMs with a vast compilation of hydrographic soundings collected by the National Ocean Service and various academic institutions. The principal component of the database is 3-arc-second elevation grids, of areas 1degree in longitude by 1degree in latitude, in which elevations are resolved to 1/10 of a meter. The database also includes grids containing the number of soundings enclosed by each cell in the offshore areas of the elevation grids, and images of both the elevation and sounding density grids. The latter are in common graphic formats that can be displayed by a range of UNIX-based and personal computer software. Purpose: The Coastal The TIFF image generated from the Coastal Relief Model provides a base map for Geographic Information System (GIS) database.

Process_Step: Process_Description: The desired Coastal Relief Model data were extracted from volume 3 in ESRI ASCII format, and then converted to an ESRI grid. Using the ArcMap Spatial Analysis extension, a hillshade was then created from the ESRI grid file. After creating a desirable color scheme, the ESRI grid file and hillshade were combined using the ArcView extension grid-to-image converter tool (downloaded from www.esri.com) to create a TIFF image file and world file.

A shaded relief image is produced by applying an artificial light source to elevation (topographic or bathymetric) data. The azimuth, elevation, and vertical exaggeration are specified. The light source produces shadows within the imagery, as if the sun were shinning upon the region. Applying an artificial light source to elevation data, yields an image that is more easily interpreted by the end-user.
