With the Age of Discovery, during the 15th to 18th centuries, world maps became increasingly accurate; exploration of Antarctica, Australia, and the interior of Africa by western mapmakers was left to the 19th and early 20th century.

world map, graphical representation, using projection, that depicts Earth’s exterior on a flat surface. World maps usually show political features, such as country borders, and physical features. World maps can also be used to present data on average temperature, soil type, rainfall distribution, and much else.
Because Earth is an ellipsoid, a world map, which presents Earth in two dimensions, is necessarily a distorted representation. (A globe, which is a model of Earth, eliminates distortion by presenting a map of the world on the surface of a sphere.) World maps have evolved over time to manage these distortions through a variety of transformations, known as projections, which became more important as world maps gradually included everything on Earth. Early world maps did not include the entirety of Earth’s surface as we know it today, as no single polity or culture had explored all regions. This limited knowledge meant that one all-encompassing world map was not possible until relatively recently.
The first known map of the “world,” now located at the British Museum, is a cuneiform clay tablet from Mesopotamia, dated to about the 6th century bce and known as the Babylonian Map of the World. This map has two concentric circles, with the outer circle labeled “Bitter River” and the inner circle containing a representation of the city of Babylon bisected by the Euphrates River. This tablet is considered the first documented attempt by humans to graphically define the space in which they were living. By equating Babylon with the world, the map also served as a symbol of Babylonian power.
World maps through the ages have followed the pattern first laid by this Babylonian tablet: They have represented the mapmaker’s worldview, which necessarily expresses the cultural and political biases that are embedded in those views. As mapmakers’ perception and understanding of the world have changed, so have world maps. Until technical innovations—including those from the age of exploration up to modern-day satellite photography—enabled the accurate recording and measurement of Earth’s surface, large areas could be perceived only by standing atop towers, hilltops, or other human-made or natural heights, allowing a person a bird’s-eye view. Early maps were thus diagrams pieced together by the people who made these observations. Those who constructed early world maps also had access to the tools of astronomy, which they used to observe the movements of the Sun and the stars and thus estimate Earth’s size and shape. All of these methods often led to errors in depicting Earth, however, which meant that the makers of world maps faced numerous challenges.
The first challenge that early mapmakers faced was completeness: Did their world map provide a view of all known lands and oceans? This issue slowly resolved itself as exploration helped fill in the gaps. Unknown sections of the world were replaced in maps with images, often of monsters. These sections, sometimes referred to as terra incognita, were filled in over time. A map of the Roman Empire known as the Tabula Peutingeriana is a narrow but very long scroll—clearly an unrealistic and incomplete representation of the world, but it was successful in showcasing the reach of the Roman Empire.
The first realistic world map is credited to Ptolemy, who created it in the 2nd century ce. Ptolemy collected documents detailing locations of towns, added information gathered from travelers, and came up with a system of latitude and longitude to plot thousands of places from Britain to Asia to North Africa. A believer in the spherical Earth, Ptolemy also successfully tackled the problems posed by projection. Many subsequent world maps were less accurate. A map dating to 1050 at the Saint-Sever monastery in France places the Garden of Eden at its top (which, according to the map’s logic, puts it closest to the heavens). Mapmaking accelerated in Europe during the Renaissance, driven by exploration, which, in turn, grew commerce and built empires—two activities that accurate mapping greatly benefited. The first map showing North and South America clearly separated from Asia was produced in 1507 by Martin Waldseemüller (though his rendering of the American continents is barely recognizable to us today).

A second mapmaking challenge was the problem of scale: As the scale of a map increases—as more and more of the world becomes known and is depicted on a single map—the map’s level of detail, and thus accuracy, decreases. Early mapmakers did not always care much for cartographic accuracy as we understand it today; for those who did, they often lacked the instruments or technology necessary to be accurate. Christopher Columbus’s first journey across the Atlantic in the 15th century was influenced by a Ptolemaic map, which showed the world as 30 percent smaller than it is and thus misled him into believing he had arrived in India when he landed on Hispaniola. As European countries started establishing colonies across newly claimed lands, each of them mapped these regions. They also began to undertake the systematic topographic mapping of these territories, though they did so using their own standard measures of scale as well as distance. Great Britain used a 1:2,500 scale in 1858, while in the 19th century unified Germany was mapped at 1:100,000. It was only in 1891 that the International Geographical Congress proposed that participating countries collaborate in the production of a 1:1,000,000-scale world map, which in turn led to increasing standardization of cartographic specifications and formats.
A third challenge confronted in early world maps was that of perspective: From what viewpoint does the mapmaker make the map? Early maps are—as Jerry Brotton, in A History of the World in 12 Maps (2012), has called them—“egocentric.” The focus is on the mapmaker and their immediate environs, which are typically placed, as in the Babylonian tablet, at the map’s centre. During the Renaissance, some cartographers compared those who used a map to theatregoers, as seen in the atlas Theatrum orbis terrarum (“Theatre of the World”), published in 1570 by Abraham Ortelius. Today, the technology that most often provides data for maps—and the maps themselves—also sets expectations for a map’s perspective. We see the world from the perspective of a satellite orbiting Earth, in which we can zoom in to provide a high level of detail and zoom out to provide a much wider view. Sometimes, though, cultural convention determines perspective. Modern-day world maps show north as the “up” direction, even though there is nothing intrinsic to any of the four cardinal directions that warrants picking one direction rather the others.
Most contemporary world maps have been designed using aerial photography and high-definition lenses, allowing the depiction of land and ocean boundaries with a high level of accuracy. Topographical detail can also been captured accurately, save in regions of extreme weather, such as portions of Antarctica. However, borders between and within countr...
Early world maps cover depictions of the world from the Iron Age to the Age of Discovery and the emergence of modern geography during the early modern period. Old maps provide information about places that were known in past times, as well as the philosophical and cultural basis of the map, which were often much different from modern cartography.
Jul 13, 2020 · The world map was turned with east on top, centered on the ancient city of Balasagun (Kyrgyzstan), showing the Caspian Sea to the north, and Iraq, Armenia, Yemen, and Egypt to the west, China and Japan to the east, Hindustan and Kashmir to the south. Blue lines symbolize rivers, red lines for mountains.
Oct 19, 2023 · Ptolemy created a map of the world in the 2 nd century AD using the longitudes and latitudes that we still use today. Ptolemy’s work is similar to Eratosthenes’ map, but his work is more recognized, due to the fact that he not only made a map, but also wrote a book about how he drew the map.

Jul 22, 2019 · The first ever scientific world map is most widely attributed to the Portuguese cartographer Diego Ribero. The Padrón Real was the Spanish Crown’s official and secret master map, made from hundreds of sailors’ reports of any new lands and their coordinates.
Maps have been one of the most important human inventions for millennia, allowing humans to explain and navigate their way through the world. When and how the earliest maps were made is unclear, but maps of local terrain are believed to have been independently invented by many cultures.
