Plan Curvature
The Grids | Calculate | Calculus terrain model, Plan Curvature, reflects the rate of change of the Terrain Aspect angle measured in the horizontal plane, and is a measure of the curvature of contours. Negative values indicate divergent water flow over the surface, and positive values indicate convergent flow.

Plan Curvature calculates the curvature of the surface in the horizontal plane, or the curvature of the contour. Negative curvature, shown with a gray fill, indicates areas of divergent flow. |
