A point on the globe is chosen as "the center" in the sense that mapped distances and azimuth directions from that point to any other point will be correct. That point, (φ 0, λ 0), will project to the center of a circular projection, with φ referring to latitude and λ referring to longitude.
Encodes the latitude and longitude coordinates of a location, provides a link to map of the location. This template does not work well with the Visual Editor, consider using {{coordDec}} for signed decimal degrees, {{coordDMS}} when degrees minutes and seconds are specified {{coordDM}} when only degrees and minutes are specified. To use this template you will need to use positional parameter ...
[1] [2] [3] In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane. [4] [5] Projection is a necessary step in creating a two-dimensional map and is one of the essential elements of cartography.
Some, such as al-Khwarizmi, further developed these works, including creating maps on a graticule of latitude and longitude. During the European Middle Ages, graticules disappeared from the few maps that were produced; T and O maps in particular were more concerned with religious cosmology than accurate representation of location.
A geographic coordinate system (GCS) is a spherical or geodetic coordinate system for measuring and communicating positions directly on Earth as latitude and longitude. [1] It is the simplest, oldest and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others.
Coordinate values (latitude, longitude, and altitude) should be delimited by spaces. The decimal point is a part of the value, thus must usually be configured by the operating system. [a] Multiple locations should be represented by multiple lines. Latitude and longitude should be displayed by sexagesimal fractions (i.e. minutes and seconds).
San Francisco [17] is at 122.41°W longitude and Richmond, Virginia, [18] is at 77.46°W longitude. They are both at about 37.6°N latitude (±.2°). They are both at about 37.6°N latitude (±.2°). The approximately 45° of longitude difference translates into about 180 minutes, or 3 hours, of time between sunsets in the two cities, for example.
A globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve purposes similar to maps, but, unlike maps, they do not distort the surface that they portray except to scale it down. A model globe of Earth is called a terrestrial globe. A model globe of the celestial sphere is called a celestial globe.
