Returns a catalog of terrain metrics, labels, process groups, assumptions,
and source functions used by blueterra.
Value
A tibble with columns metric, label, process_group,
description, units, source_function,
requires_optional_dependency, scale_sensitive, and
interpretation_notes.
Details
The catalog is an interpretation aid, not a claim that terrain metrics directly measure ecological or oceanographic processes. Groups such as seafloor aspect, slope gradient, accumulation potential, seafloor position, seafloor rugosity, downslope pathway proximity, transport potential, and curvature describe terrain form and terrain-routing proxies. Accumulation, pathway, and transport interpretations require separate validation and are not direct current or sediment-flux measurements.
