USGS updates its Maine topo maps

US, October 28, 2014: US Geological Survey (USGS) recently released new topo maps for Maine that feature segments of the Appalachian National Scenic Trail (AT). Several of the 715 new US topo quadrangles for the state now include parts of the Trail along with other improved data layers.

To create these maps, USGS partnered with the National Park Service and the Appalachian Trail Conservancy and incorporated the trail data onto the Maine US Topo maps. This NST joins the Ice Age National Scenic Trail, the Pacific Northwest National Scenic Trail the North Country National Scenic Trail and the Pacific Crest National Scenic Trail. The USGS hopes to eventually include all National Scenic Trails in The National Map products. These new maps replace the first edition US topo maps for Maine and are available for free download from The National Map and the USGS Map Locator & Downloader website.

The Appalachian National Scenic Trail is a public footpath that traverses more than 2,100 miles of the Appalachian mountains and valleys between Katahdin, Maine (northern terminus), and Springer Mountain, Georgia (southern terminus). It winds through scenic, wooded, pastoral, wild, and culturally resonant lands along this ancient mountain range. With more than 99% of the AT’s corridor on Federal or State land, it is the longest continuously marked, maintained, and publicly protected trail in the United States.

Matt Robinson, National Park Service GIS Specialist for the AT said, “Having its route accurately depicted on these new US topo maps just makes it even more accessible to all who wish to explore this great resource.”

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
