Geographic Resources Division

Understanding park information within its geographical context is critical to resource management. The National Park Service Intermountain Region Geographic Resources Division helps parks deploy a diverse array of geospatial tools and solutions, including Geographical Information Systems (GIS), remote sensing, Global Positioning System (GPS), and cartography.

The program supports and advises parks in hardware/software and licensing, data collection and management, and large data collection (e.g., aerial photography and LiDAR). It also provides on-line services and mapping applications support for better management of parks' spatial data and effective distribution of that data to other parks, programs, agencies, and the public.

National Park Service Data


The Integrated Resource Management Applications (IRMA) Portal is a web-based "one-stop" for data and information related to National Park Service natural and cultural resources. From IRMA you can search for, view, and download documents, reports, publications, data sets, and park species lists. You can get information on park visitor numbers, park projects, and apply for a park research permit.

National Historic Trails are designated to protect the remains of significant overland or water routes to reflect the history of the nation. They represent the earliest travels across the continent on the Juan Bautista de Anza National Historic Trail; the nation's struggle for independence on the Overmountain Victory National Historic Trail; epic migrations on the Mormon & Oregon Trails and the development of continental commerce on the Santa Fe Trail. They also commemorate the forced displacement and hardships of the Native Americans, on the Trail of Tears. There are 19 Historic Trails.
