Aspect

Aspect represents the azimuth of the sloped surfaces across a landscape. Aspect data were provided by the Elevation Derivatives for National Applications (EDNA) dataset. EDNA topographic data were derived from the National Elevation Dataset (NED). NED comprises merged 7.5 minute quadrangle topographic data resulting in a high quality, consistent elevation data set that spans the nation. Aspect unit measurements are degrees.
