Cartography of the United States addresses the production, dissemination, and use of maps within the United States from colonial exploration to contemporary geospatial science. The field intersects exploration, surveying, legislation, and technology as reflected in maps produced by figures and institutions associated with Jamestown, Boston, Philadelphia, New York City, Washington, D.C.. Cartographic practice influenced territorial disputes, infrastructure, and public policy across eras exemplified by interactions among Lewis and Clark, Thomas Jefferson, Benjamin Franklin, Alexander Hamilton, and later federal agencies.

History of United States Cartography

Early mapping in North America involved explorers such as John Smith, Samuel de Champlain, Henry Hudson, and cartographers tied to Spanish Empire voyages and the French and Indian War. Colonial-era printing and engraving by Benjamin Franklin, Paul Revere, William Faden, and John Rocque fed into Revolutionary-era needs of Continental Congress planners and military leaders including George Washington and Nathanael Greene. Post-independence surveys by Thomas Jefferson and the federal initiatives of the Survey of the Coast and United States Army Corps of Engineers linked to westward expansion driven by the Louisiana Purchase and the Lewis and Clark exploration. The 19th century saw advances from the United States Geological Survey beginnings and state geological surveys influenced by Asa Gray and Charles Wilkes, with railroads like Union Pacific Railroad commissioning township maps used by financiers such as Jay Cooke. Cartography matured through the Civil War era mapping of Ulysses S. Grant and Robert E. Lee campaigns, and into the 20th century with topographic mapping for projects such as the Panama Canal and New Deal-era mapping linked to Franklin D. Roosevelt initiatives.

Geographic and Thematic Mapping Practices

Topographic traditions in the United States were institutionalized by the United States Geological Survey and state geological surveys; thematic mapping traditions were advanced by statisticians and reformers such as Florence Nightingale analogues in U.S. public health, and by cartographers working with the United States Census Bureau, Bureau of Land Management, National Oceanic and Atmospheric Administration, and United States Forest Service. Nautical charts produced by the United States Coast Survey and later National Oceanic and Atmospheric Administration supported commerce in ports like New Orleans, San Francisco, and Boston Harbor. Thematic maps for transportation by Interstate Highway System planners, hydrology by Army Corps of Engineers, and land use by Soil Conservation Service informed policies debated in venues such as the United States Senate and adjudicated under laws including the Homestead Act and decisions from the Supreme Court of the United States. Urban mapping practices evolved in cities like Chicago, Los Angeles, Philadelphia, and New York City supporting zoning linked to the Zoning Resolution of 1916 and municipal planning commissions such as those in Boston and Portland, Oregon.

Cartographic Agencies and Institutions

Federal agencies central to U.S. cartography include the United States Geological Survey, United States Census Bureau, National Aeronautics and Space Administration, National Geospatial-Intelligence Agency, National Oceanic and Atmospheric Administration, and the Bureau of Land Management. Academic centers such as Harvard University, Columbia University, University of California, Berkeley, University of Michigan, and Pennsylvania State University have hosted cartography and geography programs tied to scholars like Carl O. Sauer and institutions including the Library of Congress and the Smithsonian Institution. Professional organizations such as the Association of American Geographers and the American Congress on Surveying and Mapping shaped standards adopted by state agencies and private firms like ESRI, The Sanborn Map Company, and mapping publishers in Boston and Chicago.

Map Projection, Datum, and Coordinate Systems

Adoption of projection standards and datums involved international and domestic actors: the Mercator projection and Lambert conformal conic projections were used for navigation and aeronautical charts by National Oceanic and Atmospheric Administration and Federal Aviation Administration. The shift from regional datums to the North American Datum of 1983 and later the North American Datum of 1927 concerns was guided by collaborations among National Geodetic Survey, United States Geological Survey, and international partners like International Association of Geodesy. Coordinate systems used include the Universal Transverse Mercator coordinate system applied by the United States Army Corps of Engineers and state plane coordinates administered by state departments of transportation such as those in California, Texas, and New York. Geodetic control networks established by figures associated with Ferdinand Hassler and agencies such as the Coast and Geodetic Survey underpinned modern GPS integration led by National Aeronautics and Space Administration and the Department of Defense.

Cartographic Technology and Techniques

Technological shifts from lithography and copperplate engraving by printers in Philadelphia and London to photogrammetry used by United States Geological Survey and aerial mapping by companies serving Pan American World Airways and the United States Air Force revolutionized map production. Digital transitions saw the rise of Geographic Information System software developed by ESRI and research at Stanford University, University of California, Santa Barbara, and Massachusetts Institute of Technology; satellite remote sensing from Landsat program and missions coordinated with National Aeronautics and Space Administration and United States Geological Survey provided raster data for national mapping programs. Cartographic standards codified by the International Cartographic Association and professional bodies informed symbology used in atlases such as those by Rand McNally and the National Geographic Society.

Cultural, Political, and Legal Aspects of Mapping

Maps in the United States have been tools in territorial adjudication before the Supreme Court of the United States, in indigenous land rights claims involving tribes such as the Navajo Nation, Cherokee Nation, and Sioux nations, and in treaties like the Treaty of Guadalupe Hidalgo. Cartography has intersected with civil rights contexts in redistricting litigation under statutes including the Voting Rights Act of 1965 and cases heard in federal courts and state supreme courts. Copyright and access issues engaged the Library of Congress, private publishers like Rand McNally and technology firms including Google and Microsoft Corporation in debates over public-domain geospatial data and licensing. Environmental mapping by agencies such as the Environmental Protection Agency influenced litigation over the Clean Air Act and Clean Water Act enforcement.

Notable Maps and Mapmakers of the United States

Prominent mapmakers include Benjamin Franklin, David Rumsey-era collectors, surveyors like Ferdinand Hassler, explorers Meriwether Lewis and William Clark, and cartographers such as John Melish, Aaron Arrowsmith, Lewis H. Latimer-era inventors, and publishers including Rand McNally and The Sanborn Map Company. Landmark maps include colonial charts by John Smith, the 1804-1806 maps of the Lewis and Clark journey, Civil War atlases used by Abraham Lincoln administration strategists, the topographic quadrangles of the United States Geological Survey, thematic census maps by the United States Census Bureau, and modern datasets from the National Geospatial-Intelligence Agency and the Landsat program.
