Slope Direction maps can provide the inspector with information to determine the most suitable vegetation for a site, depending on what has been identified for the post-mining land use. Slope Direction Maps were identified by the inspectors as an added benefit. Slope aspect maps can be readily created from the DSM derived from stereo high resolution orthorectified imagery. Aspect was computed on the same small regraded area as the Slope Angle map at the McKinley mine site (See Slope Angle Map of McKinley several figures above). The legend for the map below shows ten directional aspect categories expressed in degrees measured clockwise from true north. The map indicates that the dominant aspect directions in the area of interest are Northwest to North trending.
