Summary
Abstract: Digital Elevation Model (DEM) is the terminology adopted by the USGS
to describe terrain elevation data sets in a digital raster form.
The standard DEM consists of a regular array of elevations cast on a
designated coordinate projection system. The DEM data are stored as
a series of profiles in which the spacing of the elevations along
and between each profile is ... View entire text

Purpose: DEMs can be used as source data for digital orthophotos, and for
earth science analysis as layers in geographic information systems.
DEMs can also serve as tools for volumetric analysis, for site
location of towers, or for drainage basin delineation. These data
were collected as part of the National Mapping Program.

Quality Attribute_Accuracy_Report:
The accuracy of a DEM depends upon the source level of detail and
the resolution of the data samples. The primary limiting factor for
the source level of detail is the scale of the source materials. The
proper selection of grid spacing determines the level of content
that may be extracted from a given ... View entire text
