New USGS Maps Add National Park Service Data
Enhanced US Topo maps feature national park trails and amenities
National Scenic Trails
The USGS National Geospatial Program works to add National Scenic Trails to updated US Topo Maps
Newly released US Topo maps are now available and for the first time, the maps covering Great Smoky Mountains National Park display trails, campgrounds, visitor centers, boundaries and other visitor information in a national park.
New US Topo maps for North Carolina and Tennessee are now available and for the first time, the maps show trails, campgrounds, visitor centers, and other visitor information in a national park. These quadrangles are available from the USGS for free download.
“Across the country, visitors to national parks will benefit from these new features on maps, but it’s especially fitting that the nation’s most visited national park - the Great Smoky Mountains National Park - is the inaugural park for the joint pilot project between the USGS and the NPS," said Kari Craun, Director of the USGS National Geospatial Technical Operations Center. “We look forward to continuing our work with the Park Service by adding this important and useful data to US Topo products nationwide.”
“As we celebrate our 100th anniversary, our program focuses on connecting new generations to parks with digital map technology,” said Julie Recker, Enterprise Geographic Information Systems manager for the NPS. “The NPS plans to share data from its central GIS data warehouse to the USGS National Map and Topo products, as part of the NPS Centennial Call to Action ‘Going Digital.”’
Great Smoky Mountains National Park was established in 1934. It straddles North Carolina and Tennessee and covers more than 816 square miles. With more than 10 million visitors per year, the park is known for its scenic vistas, lush forests, abundance of wildflowers, and miles of hiking trails, including a segment of the Appalachian National Scenic Trail.
The addition of the Appalachian Trail segments is an ongoing project for the USGS to eventually include all National Scenic Trails in The National Map products. The segment collection includes parts of the Ice Age National Scenic Trail, the Pacific Northwest National Scenic Trail the North Country National Scenic Trail, the Pacific Crest National Scenic Trail, the Arizona National Scenic Trail, the Natchez Trace National Scenic Trail, the New England National Scenic Trail and the Continental Divide National Scenic Trail. The addition of the NPS trails information to US Topo products will provide additional value to recreational hikers venturing beyond the National Scenic Trails.
Other improvements to the new US Topo quadrangles are the inclusion of the U.S. Census Bureau’s Topologically Integrated Geographic Encoding and Referencing (TIGER) road data, the integration of wetlands layers using data from the U.S. Fish & Wildlife Service National Wetlands Inventory, along with the continued incorporation of high-resolution streams and rivers from the National Hydrography Dataset.
“The nationwide similarity in the look and feel of the maps, as well as a very widespread understanding of how to use them, make USGS topographic maps the best mapping tool for park employees, emergency personnel, and visitors,” said Great Smoky Mountains National Park Superintendent Cassius Cash. “It is my hope that we can replicate this relationship with all 411 units across the country.”
The US Topo map improvement program is nearing the end of its third, three-year cycle of revising and updating digital US Topo quadrangles. These new US Topo maps replace the second edition US Topo maps and are available for no-cost file download from The National Map Download client and several other USGS applications.
To compare change over time, scans of legacy USGS topo maps, some dating back to the late 1800s, can be downloaded from the USGS Historical Topographic Map Collection.
