# 0 degree latitude

Zero degrees latitude is the line designating the Equator and divides the Earth into two equal hemispheres (north and south). It was introduced by Legendre and Bessel who solved problems for geodesics on the ellipsoid by transforming them to an equivalent problem for spherical geodesics by using this smaller latitude. A further conformal transformation from the sphere to the plane gives a conformal double projection from the ellipsoid to the plane. Enter the specific latitude.  â 0.5 degrees and Learn how and when to remove this template message, PhilosophiÃ¦ Naturalis Principia Mathematica, "Department of Defense World Geodetic System 1984", Resources for determining your latitude and longitude, Convert decimal degrees into degrees, minutes, seconds, Distance calculation based on latitude and longitude, Determination of Latitude by Francis Drake on the Coast of California in 1579, Map projection of the tri-axial ellipsoid, https://en.wikipedia.org/w/index.php?title=Latitude&oldid=996448293, Short description is different from Wikidata, Articles needing additional references from February 2019, All articles needing additional references, Articles with unsourced statements from December 2011, Pages using Sister project links with default search, ÐÐµÐ»Ð°ÑÑÑÐºÐ°Ñ (ÑÐ°ÑÐ°ÑÐºÐµÐ²ÑÑÐ°)â, Srpskohrvatski / ÑÑÐ¿ÑÐºÐ¾ÑÑÐ²Ð°ÑÑÐºÐ¸, Creative Commons Attribution-ShareAlike License, This page was last edited on 26 December 2020, at 17:52. have a latitude of zero, and they form the line called the answer explanation . It has a latitude of 0 degrees. The pictures, and stories about the visits, will then be posted here. The equator is one of the five notable circles of latitude on Earth; the other four are both polar circles (the Arctic Circle and the Antarctic Circle) and both tropical circles (the Tropic of Cancer and the Tropic of Capricorn). The authalic (Greek for same area) latitude, Î¾, gives an area-preserving transformation to a sphere. Latitude and longitude together with some specification of height constitute a geographic coordinate system as defined in the specification of the ISO 19111 standard.[a]. 0 0. 1 decade ago. ϕ The true vertical, the direction of a plumb line, is also the gravity direction (the resultant of the gravitational acceleration (mass-based) and the centrifugal acceleration) at that latitude. This is not the only way of generating such a conformal projection. The plane of Earth's equator, when projected outwards to the celestial sphere, defines the celestiâ¦ 7 Answers. In addition, the clock is generally shifted one hour forward between April and October. Enter an address or place name and get its GPS coordinates in several formats. This script will calculate the length of one degree of both latitude and longitude, for a specific latitude. Input: Observer (Lat,Lon WGS84 coordinates) and an â¦ There are two methods of proceeding. The primary reference points are the poles where the axis of rotation of the Earth intersects the reference surface. The relation of Cartesian and spherical polars is given in Spherical coordinate system. 30 seconds . Answer Save. In English texts the latitude angle, defined below, is usually denoted by the Greek lower-case letter phi (Ï or Ï). The series method is not applicable to the isometric latitude and one must use the conformal latitude in an intermediate step. VeggieTart -- â¦ Since there are many different reference ellipsoids, the precise latitude of a feature on the surface is not unique: this is stressed in the ISO standard which states that "without the full specification of the coordinate reference system, coordinates (that is latitude and longitude) are ambiguous at best and meaningless at worst". The parametric latitude can also be extended to a three-dimensional coordinate system. It is by pure coincidence that the coordinate of 0 degrees latitude, 0 degrees longitude falls in the middle of a little-known body of water. The Equator is the line of 0 degrees latitude. "Oblate ellipsoid of revolution" is abbreviated to 'ellipsoid' in the remainder of this article. The graticule on the ellipsoid is constructed in exactly the same way as on the sphere. What does contingent mean in real estate? Before you can interpret the map above, you need to know about the pair of numbers used to plot map coordinates: latitude and longitude.Latitude is the Check that the first number in your latitude coordinate is between -90 and 90. The latitude has the symbol of phi, and it shows the angle between the straight line in the certain point and the equatorial plane. Address field - enter an address, city, state, place name, postal code or any other name for a location into this field and then click the find button to retrieve its latitude-longitude coordinate pair. No higher accuracy is appropriate for R since higher-precision results necessitate an ellipsoid model. At an arbitrary point P consider the line PN which is normal to the reference ellipsoid. The geodetic coordinates P(É¸,Î»,h) are the latitude and longitude of the point N on the ellipsoid and the distance PN. Two parameters are required. When did organ music become associated with baseball? To be exact, the intersection of zero degrees latitude and zero degrees longitude falls about 380 miles south of â¦ location. Every location consists of a latitude and longitude which is like an unique address for each point. Tropical. The direction of PN will also differ from the direction of a vertical plumb line. [​1⁄2, ​2⁄3, ​3⁄4, 1, 1] Each degree (°) is subdivided into 60 minutes (') and each minute into 60 seconds ("). where the constant C takes on the values Planes parallel to the equatorial plane intersect the surface in circles of constant latitude; these are the parallels. The length of 1 minute of latitude is 1.853 km (1.151 statute miles) (1.00 nautical miles), while the length of 1 second of latitude is 30.8 m or 101 feet (see nautical mile). It has the same symbol “°” to show degrees. Many different reference ellipsoids have been used in the history of geodesy. Latitude increases as you go North, making the Northern Hemisphere positive latitude and the Southern Hemisphere negative latitude. Many maps maintained by national agencies are based on older ellipsoids, so one must know how the latitude and longitude values are transformed from one ellipsoid to another.
