Description:

Abstract:

Topographic data was compiled by Photo Science, Inc. from 1:7200 scale aerial vertical photography dated March 1990, and exposed at an altitude of 3600 feet above mean terrain. Control for photogrammetric compilation was obtained by GPS ground survey, supplemented by data computed by aerotriangulation.

Purpose:

The contour layer is used to create slope maps and for general site planning by citizens and developers.

Supplemental_Information:

The contour layer is made up of contour lines of equal elevation. The topo contours are at 2 foot intervals. Horizontal and vertical datum refer to U.S. survey feet. They are available for the entire county with the exception of the military bases.
