Aspect represents the azimuth of the sloped surfaces across a landscape. This dataset was derived from the Elevation Derivatives for National Applications (EDNA), a multi-layered database that provides systematic and consistent topographically-derived hydrologic derivatives. The aspect grid defines downslope direction. Derived aspect values were reclassified into 0, 90, 180, and 270, with -1 values classified as 180. These four classes are sufficient to support fire behavior modeling. This dataset was subset for use in the West Wide Wildfire Risk Assessment. The data was subset by: Sanborn Solutions 610 SW Broadway, Ste #310 Portland, OR 97205 (503)228-8708 |
