These datasets are described in detail at the NGDC website: http://www.ngdc.noaa.gov/mgg/fliers/01mgg04.html The five major data sources were assembled into the single ETOPO2 2-minute data base without formal edge matching or other methods that alter the data as initially posted. Higher-resolution data take precedence: data derived from GLOBE mask all other data, Smith/Sandwell data come next, followed by IBCAO, with the 5-minute data filling any gaps. Five-minute data from DBDBV and ETOPO5 and 30-second data from GLOBE were regridded to 2 minute spacing by bicubic spline interpolation. IBCAO data were originally gridded in a polar stereographic projection; these data were interpolated along lines of constant latitude at 2 minute steps for every 2 minutes of latitude from 72° North to the pole. Purpose: The TIFF image generated from the ETOPO2 Model provides a base map for Geographic Information System (GIS) database.

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.
