Political and physical world map from the end of 2005

An atlas is a collection of maps, traditionally bound into book form, but now most often found in multimedia formats. As well as geographic features and political boundaries, many often feature geopolitical, social, religious and economic statistics.

The first known book that could be called an atlas was constructed from the calculations of Claudius Ptolemy, a Greek geographer working in Alexandria circa A.D. 150. The first edition was published in Bologna in 1477 and was illustrated with a set of 27 maps, though scholars say that it is not known whether the printed maps were engraved versions of original maps made by Ptolemy, or whether they were constructed by medieval Greek scholars from Ptolemy's text.

Atlas of Greek mythology

The origin of the term atlas is a common source of misconception, perhaps because two different mythical figures named 'Atlas' are associated with mapmaking. King Atlas, a mythical King of Mauretania, was, according to legend, a wise philosopher, mathematician and astronomer who supposedly made the first celestial globe. However, the more widely known Atlas is a figure from Greek mythology.

An atlas is a collection of maps; it is typically a map of Earth or a region of Earth, but there are atlases of the other planets (and their satellites) in the Solar System. Furthermore, atlases of anatomy exist, mapping out the human body or other organisms.[1] Atlases have traditionally been bound into book form, but today many atlases are in multimedia formats. In addition to presenting geographic features and political boundaries, many atlases often feature geopolitical, social, religious and economic statistics. They also have information about the map and places in it

Oceans map
Credit: Alexandre Van de Sande
Oceans cover almost three quarters (71%) of the surface of the Earth, and nearly half of the world's marine waters are over 3000 m deep. This global, interconnected body of salt water, called the World Ocean, is divided by the continents and archipelagos into the following five bodies, from the largest to the smallest: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Southern Ocean, and the Arctic Ocean. Official boundaries are defined by the International Hydrographic Organization.

Ptolemy's world map

The Geographia is Ptolemy's main work besides the Almagest. It is a compilation of what was known about the world's geography in the Roman Empire of the 2nd century. Ptolemy relied mainly on the work of an earlier geographer, Marinos of Tyre, and on gazetteers of the Roman and ancient Persian empire, but most of his sources beyond the perimeter of the Empire were unreliable.

Ptolemy also devised and provided instructions on how to create maps both of the whole inhabited world (oikoumenè) and of the Roman provinces. In the second part of the Geographia he provided the necessary topographic lists, and captions for the maps. His oikoumenè spanned 180 degrees of longitude from the Canary islands in the Atlantic Ocean to China, and about 80 degrees of latitude from the Arctic to the East Indies and deep into Africa; Ptolemy was well aware that he knew about only a quarter of the globe.

James Cook's 1775 Chart of Newfoundland

Captain James Cook FRS RN (27 October 1728 (O.S.) – 14 February 1779) was an English explorer, navigator and cartographer. Ultimately rising to the rank of Captain in the Royal Navy, Cook was the first to map Newfoundland prior to making three voyages to the Pacific Ocean during which he achieved the first European contact with the eastern coastline of Australia, the European discovery of the Hawaiian Islands, and the first recorded circumnavigation of New Zealand.

Cook accurately charted many areas and recorded several islands and coastlines on Europeans' maps for the first time. His achievements can be attributed to a combination of seamanship, superior surveying and cartographic skills, courage in exploring dangerous locations to confirm the facts, an ability to lead men in adverse conditions, and boldness both with regard to the extent of his explorations and his willingness to exceed the instructions given to him by the Admiralty.
