Ruggedness Index
A measure of terrain roughness based on vertical displacement per kilometer. Values >50 indicate significant technical effort.
57.6
Tortuosity Index
The ratio of actual trail distance to straight-line distance. Higher values (e.g. >2.0) indicate a winding route with many switchbacks.
