Aspect identifies the downslope direction of the maximum rate of change in value from each cell to its neighbors . Aspect can be thought of as the slope direction. The values of the output raster are the compass direction of the aspect.
Notes
The Aspect function is often applied to a digital elevation model (DEM).
The aspect dataset appears as a grayscale image. The default data type is 16 Bit Unsigned (Short Integer).
You can add the Colormap function to display the dataset using the color map renderer or a specified color scheme. Use the following parameter settings to produce consistent color mapping for your aspect datasets:
- Raster—Your aspect output
- Color Scheme Type—Color Ramp
- Color Ramp—The first color ramp (named Aspect)
