Ridgelines: Department of Interior Definition

Published by National Renewable Energy Laboratory (NREL) | Department of Energy | Metadata Last Checked: June 28, 2025 | Last Modified: 2024-09-30T20:36:03Z

This dataset represents ridgelines as defined by the Department of Interior (DOI): "Areas within 660 feet of the top of the ridgeline, where a ridgeline has at least 150 feet of vertical elevation gain with a minimum average slope of 10 percent between the ridgeline and the base." The dataset was created using the Geomorphons package from the University of Guelph, which can be found here: Geomorphons Package, and the 3DEP 1/3 arc-second digital elevation model. A TIF data file and a PNG map of the data are provided.
