The Topographic and Bathymetric Shaded Relief of North America map layer shows depth and elevation ranges using colors, with relief enhanced by shading. The image was derived from two pre-existing map layers; the Bathymetric Shaded Relief of North America, derived from ETOPO2 data, and the Color North America Shaded Relief, derived from GTOPO30 data.

The North America elevation data were derived from the GTOPO30 elevation dataset (http://eros.usgs.gov/products/elevation/gtopo30.html) produced by the U.S. Geological Survey and from the Canada3D elevation dataset produced by the Centre for Topographic Information (Sherbrooke), Natural Resources Canada. GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer). GTOPO30 was derived from several raster and vector sources of topographic information. It was developed between 1993 and 1996 through a collaborative effort led by staff at the U.S. Geol The North America elevation data were derived from the...
