Usage

classify_features_ff(slope_tolerance = 1, curvature_tolerance = 1e-04)

Arguments

slope_tolerance

Slope tolerance that defines a 'flat' surface (degrees; default is 1.0). Relevant for the features layer.

curvature_tolerance

Curvature tolerance that defines 'planar' surface (default is 0.0001). Relevant for the features layer.

Value
