  Description:
    Abstract:
      "roughness" of the terrain calculated in ARC/Info version7.0.2 using FOCALSTD command on cropped USGS DEM (see text below).  
      This calculates the standard deviation of grid values (in this case elevation) in a moving window for each cell.  I did this using a circular window with a radius of 10 cells, or 300meters.   (see Arc Help references.) 
      (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.
