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 ...
Species richness, or biodiversity, increases from the poles to the tropics for a wide variety of terrestrial and marine organisms, often referred to as the latitudinal diversity gradient. [1] The latitudinal diversity gradient is one of the most widely recognized patterns in ecology. [1] It has been observed to varying degrees in Earth's past. [2]
It is possible to reduce the various geodesic problems into one of two types. Consider two points: A at latitude φ 1 and longitude λ 1 and B at latitude φ 2 and longitude λ 2 (see Fig. 1). The connecting geodesic (from A to B) is AB, of length s 12, which has azimuths α 1 and α 2 at the two endpoints. The two geodesic problems usually ...
Map of San Francsico Bay Area. Module:Location map/data/San Francisco Bay Area is a location map definition used to overlay markers and labels on an equirectangular projection map of San Francisco Bay Area. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
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.
Overview Data visualization is one of the steps in analyzing data and presenting it to users. Partial map of the Internet early 2005 represented as a graph, each line represents two IP addresses, and some delay between those two nodes. The field of data and information visualization has emerged "from research in human–computer interaction, computer science, graphics, visual design ...
n. -vector. The n-vector representation (also called geodetic normal or ellipsoid normal vector) is a three-parameter non-singular representation well-suited for replacing geodetic coordinates ( latitude and longitude) for horizontal position representation in mathematical calculations and computer algorithms. Geometrically, the n -vector for a ...
Map of Virginia (click on map to see larger image) Module:Location map/data/USA Virginia is a location map definition used to overlay markers and labels on an equirectangular projection map of Virginia. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
