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.

1km-resolution topogrphical layer derived from USGS TOPO30
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...
