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:

Used to show minor elevation change in areas that are relatively flat

Supplemental_Information:

This layer is made up of individual points depicting elevation. Horizontal and vertical datum refer to U.S. survey feet. They are available for the entire county with the exception of the military bases.
