Shaded Elevation Map of Ohio
2002 (revised 2003)
By Donovan M. Powers, James F. Laine, and Richard R. Pavey
Map MG-1 depicts the topographic relief of the Ohio landscape using color to represent elevation intervals. The colorized topography has been digitally shaded from the northwest slightly above the horizon to give the appearance of a three-dimensional surface. The map is based on elevation data from the U.S. Geological Survey's National Elevation Dataset; the grid spacing for the data is 30 meters. Lake Erie water depths are derived from National Oceanic and Atmospheric Administration data. This digitally derived map shows details of Ohio's topography unlike any map of the past.
Map MG-1 is offered in two different color options: one using bold spectral colors to emphasize elevation contrasts and the other using earthtone hues (see image above) to reflect the state's natural appearance from space.
