Detailed explanation-1: -Aspect is the compass orientation of a slope. If you are skiing or riding down a pitch, the direction that you are facing is the slope’s aspect. Forecasters commonly categorize terrain into 8 octants: North, Northeast, East, Southeast, South, Southwest, West, and Northwest.
Detailed explanation-2: -Aspect identifies the orientation or direction of slope. Aspect is the down-slope direction of a cell to its neighbors. The cell values in an aspect grid are compass directions ranging from 0 to 360. North is 0 and in a clockwise direction, 90 is east, 180 is south, and 270 is west.
Detailed explanation-3: -Aspect is defined as the directional component of the gradient vector and is the direction of maximum gradient of the surface at a given point. As with slope, aspect is calculated from estimates of the partial derivatives: Aspect is computed in degrees from due north, i.e. as an azimuth in degrees not radians.
