Abstract:

Calculated from USGS 30m DEM, using ARC/Info command CONTOUR, at 15m intervals. (From USGS web document) 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 in regular whole number intervals. The normal orientation of data is by columns and rows. Each column contains a series of elevations ordered from sourth to north with the order of the columns from east to west. THe DEM is formatted as one ASCII header record (A-record) , followed by a series of profile records (B- records) each of which include a shorth B-record header followed by a series of ASCII integer elevations per each profile. The last physical record of the DEM is an accuracy record (C- record). 7.5-minute DEM (30- by 30-m data spacing, cast on Universal Transverse Mercator (UTM) projection). Provides coverage in 7.5 by 7.5 minute blocks. Each product provides the same coverage as a standard USGS 7.5minute quadrangle without over edge.

Purpose:

Used for locating area on more regional map - so people can tell how I cropped the DEM for the Sedgwick database. DEM's can be sued as source data for digital orthophotos, and, as layers in geographic information systems, for earth science analysis. DEM's can also serve as tools for volumetric analysis, for site location of towers, or for drainage basin delinearion. These data were collected as part of the National Mapping Program.
