Helper function factory to classify morphometric features according to a modified version of Wood 1996 page 120
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
A function that can be passed to raster::overlay to classify morphometric features
