Description:
This dataset represents a shaded relief, or hillshade, for the Northern U.S. and Canada. This shaded relief raster was created from a 30 meter Digital Elevation Model (DEM) using the ArcMap geoprocessing tool "hillshade".

The DEM consists of two mosaiced datasets:

1. U.S. Geological Survey's (USGS) 30 meter National Elevation Dataset (NED) , ~1 arc-second data that is updated over large areas by integrating the 10 meter or better source data(where available), re-sampled to 1 arc-second.
2. The Canadian Digital Elevation Data, Level 1 (CDED1) The Center of Topographic Information (CTI) jointly produces the CDED with federal, provincial, and territorial government agencies as well as the private sector. The CDED consists of an ordered array of ground or reflective surface elevations, recorded in meters, at regularly spaced intervals. Time period (1980-03-01 to 2006-04-18). The CDED1 was 24 meter cells aggregated to 30 meter cells to match the U.S.G.S. NED.
