The goal of this project, which began publishing the historical scanned maps in 2011, is to provide a digital repository of USGS topographic maps, available to the public at no cost. For more than 125 years, USGS topographic maps have accurately portrayed the complex geography of the Nation. The USGS is the Nation\u2019s largest producer of printed topographic maps, and prior to 2006, USGS topographic maps were created using traditional cartographic methods and printed using a lithographic printing process. As the USGS continues the release of a new generation of topographic maps (US Topo) in electronic form, the topographic map remains an indispensable tool for government, science, industry, land management planning, and leisure.", "description": "Bookmark", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Allord, Gregory J. gjallord@usgs.gov", "givenName": "Gregory J.", "familyName": "Allord", "email": "gjallord@usgs.gov", "affiliation": [{"@type": "Organization", "name": "National Geospatial Program", "url": "https://www.usgs.gov/programs/national-geospatial-program"}]}, {"@type": "Person", "name": "Fishburn, Kristin A. kafishburn@usgs.gov", "givenName": "Kristin A.", "familyName": "Fishburn", "email": "kafishburn@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-7825-556X", "url": "https://orcid.org/0000-0002-7825-556X"}, "affiliation": [{"@type": "Organization", "name": "National Geospatial Program", "url": "https://www.usgs.gov/programs/national-geospatial-program"}, {"@type": "Organization", "name": "NGTOC Denver", "url": "https://www.usgs.gov/national-geospatial-technical-operations-center"}]}], "funder": [{"@type": "Organization", "name": "National Geospatial Program", "url": "https://www.usgs.gov/programs/national-geospatial-program"}]}
