The history of longitude describes the centuries-long effort by astronomers, cartographers and navigators to discover a means of determining the longitude of any given place on Earth. The measurement of longitude is important to both cartography and navigation. In particular, for safe ocean navigation, knowledge of both latitude and longitude ...
They settled on five themes: location, place, relationships within places (later changed to human-environment interaction), relationships between places (later shortened to movement), and region. [4] The themes were not a "new geography" but rather a conceptual structure for organizing information about geography. [1]
The following graph illustrates the variation of both a degree of latitude and a degree of longitude with latitude. The definition of geodetic latitude (ϕ) and geocentric latitude (θ). Auxiliary latitudes. There are six auxiliary latitudes that have applications to special problems in geodesy, geophysics and the theory of map projections:
Longitude at right edge of map, in decimal degrees; Precision. Longitude: from West to East this map definition covers 0.281 degrees. At an image width of 200 pixels, that is 0.0014 degrees per pixel. At an image width of 1000 pixels, that is 0.0003 degrees per pixel. Latitude: from North to South this map definition covers 0.145 degrees.
Longitude at left edge of map, in decimal degrees; right = 120 Longitude at right edge of map, in decimal degrees; Precision. Longitude: from West to East this map definition covers 12 degrees. At an image width of 200 pixels, that is 0.06 degrees per pixel. At an image width of 1000 pixels, that is 0.012 degrees per pixel. Latitude: from North ...
45.625°N 10.75°E. / 45.625; 10.75. image. Alps location map.png. Map of the Alps. Module:Location map/data/Alps is a location map definition used to overlay markers and labels on an equirectangular projection map of the Alps. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
An alternative map image, usually a relief map, which can be displayed via the relief or AlternativeMap parameters; top = 40.8 Latitude at top edge of map, in decimal degrees; bottom = 35.8 Latitude at bottom edge of map, in decimal degrees; left = -96 Longitude at left edge of map, in decimal degrees; right = -88.9 Longitude at right edge of ...
