-
[ESRI software]
Perpendicular or normal to the slope of the surface in 3D Analyst. As changes in slope are approached across the surface, the degree of smoothness is defined by how gradual or abrupt the normals to that surface change. A smooth surface has gradual changes in the normals to the surface; a planar surface has abrupt changes.
