Map ORR Digital Elevation Model 2m 1993

This Digital Elevation Model (DEM) of the Oak Ridge Reservation has a 2m spatial resolution and an error of +/- 2.32m (1:2,400scale). Melanie Harris (Qsystems) created the DEMs from a Digital Terrain Model (DTM) created from aerial photography taken during leaf-off in April of 1993. The aerial photographs were flown at 7200' Above Ground Level resulting in a nominal scale of 1:14400. The data were compiled at 1:2,400 scale (1=200') yielding the +/- 2.32m error. The original DTM was created as part of the DOE Basemapping and Imagery project for the Oak Ridge Environmental Restoration program.
