Summary

This coverage was derived from U.S. Geological Survey National Elevation Dataset (NED) Digital Elevation Models (DEMs) for all of Ohio and portions of Indiana, Michigan, Kentucky, West Virginia, Pennsylvania, and New York. The dataset is a raster grid coverage representing a 30 meter grid cell size, or 1-arc second, and is in units of decimeters. The various NED source datasets used to create this dataset came primarily from state agencies who provide such data free of any fees or charges. More information about NED data can be found at http://gisdata.usgs.net/NED/default.asp.

Purpose

This coverage was created to derive elevation and hydrography related characteristics of selected drainage basins within Ohio and portions of surrounding states for use in regression equations present by Koltun (2003). These characteristics include mean basin elevation, elevation at basin centroid, and main-channel slope. Other hydrography related uses of DEMs include the analysis of aspect, hill shade, flow accumulation, and flow direction. DEMs of 30 meter resolution are intended to be used at scales of 1:24,000 and smaller.
