# SurfacePoint

#### class SurfacePoint extends AnyRef

A representation of the approximated partial derivatives of a raster cell, and the slope and aspect that can be calculated from those values. Trigonometric values of aspect and slope, computed using the partial derivatives instead of library trigonometric functions, are also exposed for performance.
