The Maps and Cartography Portal

A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes.

Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the Earth, three dimensional, such as the interior of the Earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables.

Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the medieval Latin: Mappa mundi, wherein mappa meant 'napkin' or 'cloth' and mundi 'the world'. Thus, "map" became a shortened term referring to a two-dimensional representation of the surface of the world. (Full article...)

Cartography (/kɑːrˈtɒɡrəfi/; from Ancient Greek: χάρτης chartēs, 'papyrus, sheet of paper, map'; and γράφειν graphein, 'write') is the study and practice of making and using maps. Combining science, aesthetics and technique, cartography builds on the premise that reality (or an imagined reality) can be modeled in ways that communicate spatial information effectively.

The Pink Map (Portuguese: Mapa cor-de-rosa, "rose-coloured map"), also known in English as the Rose-Coloured Map, was a map prepared in 1885 to represent Portugal's claim of sovereignty over a land corridor connecting their colonies of Angola and Mozambique during the Scramble for Africa. The area claimed included most of what is currently Zimbabwe and large parts of modern Zambia and Malawi. In the first half of the 19th century, Portugal fully controlled only a few coastal towns in Angola and Mozambique. It also claimed suzerainty over other almost independent towns and nominally Portuguese subjects in the Zambezi valley, but could rarely enforce its claims; most of the territory now within Angola and Mozambique was entirely independent of Portuguese control. Between 1840 and 1869, Portugal expanded the area it controlled but felt threatened by the activities of other powers.

The British government refused to accept Portuguese claims not based on effective occupation, including a Portuguese offer in 1889 to abandon their claim to a transcontinental link in exchange for British recognition of its other claims. The 1890 British Ultimatum ended Portuguese claims based on historical discovery and recent exploration. The dispute seriously damaged popular perception of the Portuguese monarchy, encouraging republicanism. (Full article...)

“

Few individuals significantly alter the course of history. Fewer still modify the map of the world. Hardly anyone can be credited with creating a nation-state. Mohammad Ali Jinnah did all three.

Björn Gunnlaugsson wearing the two orders he received for his survey work. Portrait by Sigurður málari.

Björn Gunnlaugsson^[a] (25 September 1788 – 17 March 1876)^[b] was an Icelandic mathematician and cartographer. For the Icelandic Literary Society, he surveyed the country from 1831 to 1843. The results of his work were published in a topographic map of Iceland at a scale of 1:480,000 on four sheets. It was the first complete map of Iceland and, although generally dated to 1844, was not completed until 1848. It was published under the direction of Olaf Nikolas Olsen in Copenhagen. In 1849, a smaller edition on one sheet at a scale of 1:960,000 appeared. For his survey work, Björn received the Order of the Dannebrog in 1846 and the French Légion d'honneur in 1859.

The Madrid metro is the large metro system serving Madrid, the capital of Spain. It is one of the largest metro systems in the world, despite Madrid having a population of only four million. The metro opened in 1919 under the direction of the Compañía de Metro Alfonso XIII. Metro stations served as air raid shelters during the Spanish Civil War.
