Investigate alterate window sizes for standard surface derivatives #93

Open scw opened 8 years ago

scw commented 8 years ago

Existing surface first and second derivatives (slope, aspect, curvature) are currently computed on a 3x3 basis. A variety of other approaches are commonly used, with the 5x5 window typically recommended to produce more stable results given noisy inputs. Evaluate the complexity of implementing these same measures at the 5x5 scale.
