Portal:Atlas
The Atlas Portal An atlas is a collection of maps, traditionally bound into book form, but now found in multimedia formats. As well as geographic features and political boundaries, many often feature geopolitical, social, religious and economic statistics. The first 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.  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. More about Atlases...
Featured map Selected article A weather map is used to display an overview of one or more atmospheric variables at a specific time in the free atmosphere. They are used for the analysis and display of observations and computer analyses, including forecast fields derived by computer models. Maps using isotherms show temperature gradients, which can help locate weather fronts. Isotach maps, analyzing lines of equal wind speed, on a constant pressure surface of 300 mb or 250 mb show where the jet stream is located. Two-dimensional streamlines based on wind speeds at various levels show areas of convergence and divergence in the wind field, which are helpful in determining the location of features within the wind pattern. A popular type of surface weather map is the surface weather analysis, which plots isobars to depict areas of high pressure and low pressure. Special weather maps in aviation show areas of icing and turbulence. Related portalsSelected biography Piri Reis (full name Hadji Muhiddin Piri Ibn Hadji Mehmed) was an Ottoman-Turkish admiral and cartographer born between 1465 and 1470 in Gallipoli on the Aegean coast of Turkey. He is primarily known today for his maps and charts collected in his Kitab-ı Bahriye (Book of Navigation), a book which contains detailed information on navigation as well as extremely accurate charts describing the important ports and cities of the Mediterranean Sea. He gained fame as a cartographer when a small part of his first world map (prepared in 1513) was discovered in 1929 at Topkapı Palace in Istanbul. The most surprising aspect was the presence of the Americas on an Ottoman map, making it the first Turkish map ever drawn of the Americas. Related WikiProjectsSelected quote
