Description:

An aspect-slope map simultaneously shows the aspect (direction) and degree (steepness) of slope for a terrain (or other continuous surface). Aspect categories are symbolized using hues (e.g., red, orange, yellow, etc.) and degree of slope classes are mapped with saturation (or brilliance of color) so that the steeper slopes are brighter. The coloring is based on Moellering and Kimerling’s MKS-ASPECT scheme (GIS world 1991). This will create a new output grid with values in the 20s for low slope areas, 30’s for medium slope areas and 40s for high slope areas. The numbers will range from 21-28, 31-38 and 41-48 where the last digit relates to the aspect orientation (with 1 being north, 2 northeast, 3 east, 4 southeast, 5 south, 6 southwest, 7 west, 8 northwest). Numbers less than 20 are essentially flat areas and will be assigned a gray color.
