Description:
Abstract:
This dataset displays contour lines covering the Allegheny National Forest (ANF) and surrounding area at 100 foot intervals.  Each contour is a line of equal elevation, therefore, contours never cross.  They show the general shape of the terrain.  Contours that are very close together represent steep slopes.  Widely spaced contours or an absence of contours means that the ground slope is relatively level.
Purpose:
The purpose of this data is to support project-level planning, decision making, implementation and monitoring for Forest Service managers, GIS Specialists and others.

Attribute_Accuracy:
Attribute_Accuracy_Report:
The arc command LATTICECONTOUR was used on USGS DEM (Digital Elevation Model) data to produce the contour_20 (originally topo_20) coverage.  Using this command produced engineering-quality contours, representing an exact interpretation of the lattice surface model.  A weed tolerance of 2 was used with the latticecontour command.  All multiples of 100 contour lines were selected from contour_20, then saved as a shapefile.  Shapearc was used to create the coverage contour_100.  This dataset displays contours at 100 foot intervals beginning at 1000.  Contour values are included in item "contour" in the attribute table.
Logical_Consistency_Report:
This dataset was checked for topological consistency using the Arc/INFO command build.
