“Maps are communicating vast quantities of new knowledge that was only estimated. They convey this imaginative energy — an imaginative energy that maps today have lost, because today maps are so functional, so utilitarian.” — Peter Keating In the sixteenth century, Spanish cartographers represented California as an island. They weren't being careless. Nor were they drawing New Yorker covers. These 16th century cartographers were, instead, mapping the limits of both what they knew and what they imagined. Cartography is as much an art as a science and maps always mirror how we see the world. Thus Peter Keating's beautifully illustrated new book, Power Lines: Maps That Shaped the Way We See the World. Assembling nearly 100 of history's most consequential political maps, Keating's thesis is that maps are not neutral. They are arguments. Every map centers something — a religion, an empire, a people — and pushes something else to the margins. The story of cartography, then, is the story of power. Five Takeaways •       California Was an Island: The Power of Imagined Geography: In the sixteenth century, Spanish cartographers drew California as a large island off the coast of America. They weren't being careless — they were mapping the edge of what was known and imaginable. Before any map can draw a border, Keating argues, it has to decide what is real. The T-and-O medieval maps placed Jerusalem at the center of the world, with the biblically admitted lands of Europe, Africa, and Asia radiating outward. Only slowly, and with great difficulty, did the Western cartographic tradition absorb the fact that there was a whole continent between their imagination and the Pacific. •       The Oldest Tension in Cartography: Sacred vs Scientific: Keating identifies two traditions in constant tension throughout Western history. The cosmographical tradition: center what you know and believe, place your gods and sacred lands at the middle of the world, and mix fantasy with inquiry. The scientific tradition: starting with Ptolemy in ancient Greece and independently in ancient China, create maps that generals and kings could actually use to expand territory, find resources, and identify enemies. With Rome's Christianisation, the cosmographical tradition dominated for nearly a thousand years. The Ptolemaic scientific tradition only re-emerged with the Renaissance and exploration. •       Poland: The Most Erased Country in Cartographic History: Keating's answer to his own question — which country has been wiped off maps most often yet survived? Poland. It disappeared from maps at least three times, divided and partitioned by more geographically fortunate powers — Habsburgs, Russians, Nazis — whose cultural and military might seemed overwhelming. And yet Poland survived every erasure in the hearts of its people. A 1956 map of Poland as a carnation, published by the communist government as a May Day celebration, reads — Keating argues — as subversive under the surface: a nation asserting its existence against the regime that claimed to represent it. •       Lincoln's Favorite Map: The Slave Density Survey: The most powerful map in the book: the 1861 Coast Survey, a non-ideological government project that shaded American counties by the density of enslaved populations. Lincoln studied it obsessively. He reasoned that where enslaved people were densest, Union troops could arrive as liberators and find support. Where they were rare — in predominantly white areas of the South — he could pursue accommodation and peace. The map shaped the Emancipation Proclamation's geography. And because enslaved populations had settled where the delta soils were richest, the map also explains the cultural and political geography of the American South today. •       The Two-Color Election Map Is Making Democracy Worse: Every two years, Americans are shown the same red-and-blue electoral map. Keating's verdict: it is a bad projection, a winner-take-all distortion, and a representation of the Electoral College's biases rather than actual political sentiment. Research shows that two-color maps increase cynicism, cause people to underestimate the number of fellow-partisans in other states, and erode faith in politics. In a democracy, maps should reflect actual political support. The United States is overdue for population-based electoral maps. About the Guest Peter Keating is a narrative journalist whose work has appeared in GQ, Mother Jones, National Geographic, and Politico.

On this episode, hosts Peter Ravella and Tyler Buckingham talk to Rear Adm. (Ret.) Shepard Smith about his retirement after 28 years at NOAA, and his new position as chief technology officer (CTO) at XOCEAN. At NOAA, Smith rose to the rank of Rear Admiral and was closely involved in advancing state-of-the-art hydrography and nautical cartography. His ten years of working at sea included tours in Alaska, the Pacific and the Atlantic and Gulf coasts, and four years as the Commanding Officer and Chief Scientist of the NOAA Ship Thomas Jefferson. In his final role with NOAA, he served as Director of the Office of Coast Survey, where he oversaw the U.S. national programs in hydrography and nautical cartography. Smith also represented the United States at the International Hydrographic Organization and regional hydrographic commissions.  Using Uncrewed Surface Vessels (USVs), XOCEAN provides data collection services to surveyors, companies and government agencies. In his new role, Shep will lead the company into its next phase of growth, developing a new technology roadmap, advancing the boundaries of USV tech, and driving the technical vision for the business.

Hello Interactors,This post is part of a three week experiment. I’ve divided my topic into three parts each taking a bit less time for you to read or listen. They each can stand on their own (maybe), but hopefully come together to form a bigger picture. Please let me know what you think.Maps are such a big part of our daily lives that it’s easy to let them wash over us. But they’re also very powerful forms of communication that require our attention and scrutiny. If we don’t, we run the risk of being hypnotized and even deluded.As interactors, you’re special individuals self-selected to be a part of an evolutionary journey. You’re also members of an attentive community so I welcome your participation.Please leave your comments below or email me directly.Now let’s go…Someone posted a map on Facebook recently showing just how close Russia is to Alaska. The post read, “This should make you 😳 America. My kids were not taught as much geography and history as I was growing up. This probably needs to be shared to remind us all. For those who think Russia is all the way on the other side of the world [it is] only 53 miles at the Bering Strait’s narrowest point. Like us driving from Cedar Rapids to Waterloo.”The comments to the post echoed this worry with words like, “Too many don’t realize this.”; “There are small islands 25 miles apart.”; “OOOOOOOOO scary.”; and “I’ll admit that I didn’t realize this.”   They probably didn’t realize this either: the United States and Russia not only share the largest maritime border in the world – a line stretching 1600 nautical miles dividing the Chukchi Sea to the north and the Bering Sea to the south – but it cuts straight through two islands called the Diomedes. On one side is Russia’s Big Diomede – actually part of Chukotka Autonomous Okrug a federal subject of Russia – and just two miles west is Little Diomede which is part of Alaska. Both have small fishing villages, one settled by Russians and the other Americans.If folks are scared by the geographic proximity of 53 miles, two miles must really freak them out? And they’d best be sitting down for this little tidbit…there is no ratified treaty in place between the United States and Russia that enforces this boundary.The last attempts made to negotiate a deal with Russia was in 1991. The person who chaired the U.S. Senate Committee on Foreign Relations was none other than Senator Joe Biden from Delaware.Biden addressed the committee with these words,“…today the subcommittee meets to consider a measure that constitutes one small step down that path of cooperation. This measure, the U.S.-Soviet Maritime Boundary Treaty, represents the attempt of the two sides to resolve an important dispute through negotiation, compromise, and mutual pledge to abide by the solemn obligations of a bilateral treaty and international law.”The dispute this treaty would lay to rest concerns the sovereign rights and jurisdiction of the United States and the Soviet Union in the seas between Alaska and Siberia. The treaty would govern each country’s right to manage fisheries and to conduct oil and gas exploration and development in a vast maritime area.”In 1990, then Soviet Union leader, Mikhail Gorbachev sought to resolve the ordeal. But the Russian parliament believed he was acting in haste. The Soviet Union was beginning to crumble and they believed Gorbachev was giving away too much fishing, sea passage, and oil and mineral rights to the United States in exchange for other provisions. The USSR collapsed in December of 1991. This left Biden’s sixth month old efforts under the George H. W. Bush administration unanswered. No administration since has attempted to ratify the treaty and I doubt Putin is in the mood for Biden to resume talks.The area maps referred to as Russian America, a piece of land nearly the size of Texas, is what we now call Alaska. It had already been colonized by Siberian fur trappers in the 1700s and the Russian Orthodox Church was already busy trying to convert Indigenous people to Christianity. By 1800 the Russian-American Company was established – organized by Emperor Paul I of Russia. By 1850, 300,000 sea otters were hunted to extinction. Seventeen years later, in 1867, amidst a fur market slump from over hunting, the end of the U.S. Civil War, a Russia battered by the Crimea war ceded Russian America to the United States as part of the Alaska Purchase. It didn’t become a U.S. state until 1959.Russia sold Alaska to the United States for $7.2 million or $134 million in 2022 dollars. Russia feared they couldn’t defend the territory from the British who were busy trying to colonize Canada and had just defeated the Russians in the Crimea war with the help of the French. So, they expressed interest in selling it to the then U.S. Secretary of State William Seward who had already offered to buy it just a few years prior and was happy to negotiate the purchase.Biden gave reference to the purchase in his Foreign Relations subcommittee pre-amble by joking, “the 1867 Convention, by which Russia ceded Alaska to the United States, made it possible for Mr. Murkowski to become a U.S. Senator.” The Maritime Boundary Agreement this committee aimed resolve, but never did, “these conflicts by: One, declaring that the 1867 Convention line is the maritime boundary between the United States and the Soviet Union; two, establishing a precise geographic description of the line; and three, providing for the transfer of jurisdiction and Russia rights in four special areas.”The first American to map the new state of Alaska may take issue with Biden’s use of the words ‘precise geographic description.’ Land wasn’t the only thing the U.S. got for their $7.2 million, they were also handed maps and charts of the region drafted by Russian mapmakers. These were promptly handed over to the man who was soon to become the head of the Pacific branch of the Office of United States Coast Survey, and premiere geographer of the time, George Davidson.He excelled at geodesy and astronomy coming out of Girard College in 1845. By 1850 he was on the California coast determining accurate latitude and longitude of coastal features. He worked his way up the Pacific coast to Oregon and Washington mapping much of the Puget Sound and naming many of the Olympic Mountains on the Olympic Peninsula. Mt. Ellinor is named after his soon-to-be wife, Ellinor Fauntleroy. The Fauntleroy ferry in Seattle takes you from the Fauntleroy Cove to Vashon Island. Mt. Constance is named after her sister, and the two side-by-side mountains, The Brothers, are named after her two brothers.His triangulation and astronomical observations were regarded as the highest precision geodesy recorded to that date. The baselines required to accurately triangulate and map the Pacific coast states are named after him – the Davidson Quadrilaterals. And before those Russian maps had been handed over to him, he had already been asked to make maps of the physiography and natural resources of Alaska by the U.S. Congress. Most maps were copied from Russian maps and others drawn by an Indigenous Chief who knew more about the land than the Russians. A 1937 biography claims “Davidson always got on with Indians—he treated them as men.” These maps were included in a report to a congressional committee that resulted in a unanimous vote for America to purchase Russian America from the Russians.Davidson was mapping Alaska at 51° to 71° latitude north amidst the mosquitos in August of 1867, but less than a year earlier the Office of Coast Survey had sent Davidson down to 5° to 7° latitude north, in January of 1867, to map a potential site for the Panama Canal.The Office of the Coast Survey was started by Thomas Jefferson in 1807 and still publishes the nautical maps of the U.S. – including the annually published 10 volume publication, United States Coast Pilot. Historically, these guides relied on local mariner knowledge and newspaper articles. They were a practical necessity for private, commercial, and governmental mariners. But in 1858 George Davidson was the first to provide his own accounts making this issue the first official United States Coast Pilot by the Office of the Coast Survey.Davidson went on to become the president of the California Academy of Sciences, a University of California Regent, and the University of California, Berkley’s first geography professor. He was the department chair from 1898 until 1905.Davidson defined the essence of what map making was at the time. It served the desire and need Jefferson had for precision, utilizing the best surveying and geodesic instruments and techniques of the time. Naturally these were used for exacting territories for colonizing, capitalizing, and exploiting. The United States had become an exuberantly expansionist, empire-building country. But by the middle of the 19th century through the start of the 20th another kind of map was entering its golden age – thematic mapping.Thematic maps use information not readily observed but are nonetheless part of the geography. For example, maps depicting the weather or statistical information like demographics. They can also include strategic and political information.The beginning of the 20th century saw the emergence of the United States as a global superpower and the start of the decline of England’s dominance. New territories, like Alaska, were not only getting mapped but were also helping to shift geopolitical dynamics. The world was sufficiently mapped such that world leaders need not send ships afar to determine political strategies.One of the first and most influential of these geopolitical thematic maps came from England’s equivalent of George Davidson, Sir Halford John Mackinder. In 1904 he wrote a paper that included a map in The Geographic Journal called “The Geographical Pivot of History.” In the introduction here he writes,“In 400 years the outline of the map of the world has been completed with approximate accuracy…But the opening of the twentieth century is appropriate as the end of a great historic epoch…The missionary, the conqueror, the farmer, the miner, and, of late, the engineer, have followed so closely in the traveller’s footsteps that the world, in its remote borders, has hardly been revealed before we must chronicle its virtually complete political appropriation.”His map is an oval shaped Mercator projection that puts continental Europe, Africa, and Asia in the middle. Its shape gives it a spherical illusion. The map’s title is The Natural Seats of Power and features three crescent shaped concentric zones. At the center is what he called Pivot Area – which is most of continental Europe, some of Asia and what became the Soviet Union, the next ring is labeled Inner and Marginal Crescent – which is more of Europe, the British Isles and Japan, and furthest from the center are the Lands of Outer or Insular Crescent – which include continental America, most of Africa, and Australia.Part of Mackinder’s goal was to not only illustrate to an island country — that came to power by sea — just how connected the world is by land. He also simplified the complexities of detailed coastal charts and topographic maps into easy to understand centers of power. Timothy Barney, an Associate Professor of Rhetoric and Communications at the University of Richmond (and self-proclaimed map-nerd) wrote in the Routledge Handbook of Mapping and Cartography that, “Mackinder was prefiguring a social, economic, and political shift in the twentieth century towards a globalized world, all on the flat page of the map.”Mackinder would not have known it then, but his ‘Pivot Center’ indeed became the focal point of not one, but two world wars that drew powers from all three of the Natural Seats of Power on his map. But he also put thematic geopolitical mapping at the center. This is a public episode. If you would like to discuss this with other subscribers or get access to bonus episodes, visit interplace.io

Rear Admiral Shepard M. Smith is the Coast Survey director for NOAA. As director, Smith is dedicated to advancing the Coast Survey initiatives of modernizing digital charting, increasing use of autonomous systems for hydrography, and improved integrated navigation services for seaports. Rear Adm. Smith serves as a presidentially-appointed member of the Mississippi River Commission that oversees navigation and flood control projects on the largest river system in the United States. Smith also serves as the chair of the International Hydrographic Organization’s (IHO) Council that comprises 30 leading IHO member nations and oversees performance management and the business side of the IHO. Hallmarks of Smith’s career have been his leadership in the modernization of NOAA’s charting systems and transformation of NOAA’s hydrographic technologies. That leadership and experience expands Coast Survey’s data capabilities and supports a data-enabled maritime economy, among other challenges. Smith was commanding officer of NOAA Ship Thomas Jefferson, on which he served three tours during his NOAA career. During his latest tour, Smith became NOAA’s first commanding officer to operationalize autonomous surface vehicles for mapping shallow areas previously inaccessible and uncharted. While chief of Coast Survey’s Marine Chart Division, he changed the nation’s charting tradition, established in the 19th century, by restructuring chart production and distribution. This modernization makes U.S. navigational data more accessible to the public through a wider range of electronic formats. Smith holds a bachelor of science degree in mechanical engineering from Cornell University and earned a master of science degree in ocean engineering from the University of New Hampshire. He received a direct commission to the rank of ensign in the NOAA Corps in 1993.
