Slopes in Illinois Derived from the USGS Digital Elevation Model (DEM) from the Illinois State Geological Survey
Listed in NASA Earthdata CMR
Such data are useful in creating shaded relief images, characterizing topography and morphology, analyzing erosion potential and gross stream valley characteristics, and investigating the relationship between slope and other landscape features.
Description
This data set served as the ultimate parent coverage for *path_name_suppressed*/slopes This polygon data set was derived from the Triangular Irregular network (TIN) surface topography representation for the state of Illinois.
It contains over 2,800,000 million arcs and 1,800,000 million polygons. It has a file size greater than 600 Mb and is stored off-line on CD-ROM. This data set will not be made available on-line.

Refer to the data set and metadata contact for more information. Fixes needed for stslope are: Values for item RESLOPE need to be recalculated, as the decimals were rounded incorrectly. (pers comm., C. Abert 08/04/97)
