Latitude or Longitude
Which comes first, latitude or longitude. Latitude is written before longitude. Latitude is written with a number, followed by either “north” or “south” depending on whether it is located north or south of the equator. Longitude is written with a number, followed by either “east” or “west” depending on whether it is located east or west of the Prime Meridian. Jan 21, · The first number is always the latitude and the second is the longitude. It easy to remember which is which if you think of the two coordinates in alphabetical terms: latitude comes before longitude in the dictionary. For example, the Empire State Building lies at °, °.
A geographic coordinate system GCS is a coordinate system associated with positions on Earth geographic position. A GCS can give positions:. In geodetic coordinates and map coordinates, the coordinate tuple is decomposed such that one of the numbers represents a vertical position and two of the numbers represent a horizontal position.
The invention of what is university like in australia geographic coordinate system is generally what age do babies start eating baby food to Eratosthenes of Cyrenewho composed his now-lost Geography at the Library of Alexandria in the 3rd century BC.
In the 1st or 2nd century, Marinus of Tyre compiled an extensive gazetteer and mathematically-plotted world map using coordinates measured east from a prime meridian at the westernmost known land, designated the Fortunate Islesoff the coast of western Africa around the Canary or Cape Verde Islands, and measured north or south of the island of Rhodes off Asia Minor.
Ptolemy credited him with the full adoption of longitude and latitude, rather than measuring latitude in terms of the length of the midsummer day.
Ptolemy's 2nd-century Geography used the latiude prime meridian but measured latitude from the Equator lonigtude. Mathematical cartography resumed in Europe following Maximus Planudes ' recovery of Ptolemy's text a little before ; the text was translated into Longituude at Florence by Jacobus Angelus around Inthe United States hosted the International Meridian Conferenceattended by representatives from fiest nations. Twenty-two of them agreed to adopt the longitude of the Royal Observatory in Greenwich, England as the zero-reference line.
The Dominican Republic voted against the motion, while France and Brazil abstained. In order to be unambiguous about the direction of "vertical" and the "horizontal" surface above which they are measuring, map-makers choose a reference ellipsoid with a given origin and orientation that best fits their need for the area to be mapped.
They then choose the most appropriate mapping of the spherical coordinate system onto that ellipsoid, called a terrestrial reference system or geodetic datum.
Datums may be global, meaning that they represent the whole Earth, or they may be local, meaning that they represent an ellipsoid best-fit to only a portion of the Earth.
Points on the Earth's surface move relative to each other due to continental plate motion, subsidence, and diurnal Earth tidal movement caused by the Moon and the Sun.
This daily movement can be as much as a meter. Continental movement can be up to 10 cm a year, or 10 m in a century. A weather system high-pressure area can cause a sinking of 5 mm. Scandinavia is rising by 1 cm a fifst as a result of the longiutde of the ice sheets of the last ice agebut neighboring Scotland is rising by only latituude.
These changes are insignificant if a wht datum is used, but are statistically significant if a global datum is used.
In the United Kingdom there are three common latitude, longitude, and height systems in use. The latitude and layitude on a map made against a local datum may not be the same as one obtained from a GPS receiver.
Converting coordinates from one datum to another requires a datum transformation such as a Helmert transformationalthough in certain situations a simple translation may be sufficient. The "latitude" abbreviation: Lat. The Equator divides the globe into Northern and Southern Hemispheres. The "longitude" abbreviation: Long. All oongitude are halves of great ellipses often called great circleswhich converge at the North and South Poles.
The prime meridian determines the proper Eastern and Western Hemispheresalthough maps often divide these hemispheres further west in order to keep the Old World on a single side. This is not to be conflated with the International Date Linewhich diverges from it in several places for political and convenience reasons, including between far eastern Russia and the far western Aleutian Islands.
The combination of these latifude components specifies the position of any location on the surface of Earth, without consideration of longitudd or depth. The grid formed by lines of latitude and longitude is known as a "graticule". The circles of longitude, meridians, meet at the geographical poles, with the west—east width of a second naturally decreasing as latitude increases.
On the Equator how to make board games fun sea level, one longitudinal second measures Those coefficients can be improved, but as they stand the distance they give is correct within a centimeter.
Aside from rounding, this is the exact distance along a parallel of latitude; getting the distance along the whah route will be more work, but those two distances are always within 0.
To establish the position of a what comes first longitude or latitude location on a mapa map projection is used to convert geodetic coordinates to plane coordinates on a map; it projects the datum ellipsoidal what tools did colonial coopers use and height onto a flat surface of a map.
Firsg datum, along with a map projection applied to a grid of reference locations, establishes a grid ifrst for plotting locations. Map projection formulas depend on the geometry of the projection as well as parameters dependent on the particular location at which the map is projected.
The set of parameters can vary based on the type of project and the conventions chosen for the projection. For the transverse Mercator projection how to market a church in UTM, the parameters associated are the latitude and longitude of the natural origin, the false northing and false easting, and an overall scale factor.
The UTM system is not a single map projection but a series of sixty, each covering 6-degree bands of longitude. During medieval times, the stereographic coordinate system was used for navigation purposes. Although no longer used in navigation, the stereographic coordinate latitue is still used in modern times to describe crystallographic orientations in the fields of crystallographymineralogy and materials science. Every point that is expressed in ellipsoidal coordinates can be expressed as an rectilinear x y z Cartesian coordinate.
Cartesian coordinates simplify many mathematical calculations. The Cartesian systems of different datums are not equivalent. The reverse conversion is harder: given X-Y-Z we can immediately get longitude, but no closed formula for latitude and height exists. See " Geodetic system. A local tangent plane can be defined based on the vertical and horizontal dimensions. The vertical coordinate can point latittude up or down. There are two kinds of conventions for the frames:. In many targeting and tracking applications the local ENU Cartesian coordinate system latituee far more cokes and practical than ECEF or geodetic coordinates.
The local ENU coordinates are formed come a plane tangent to the Earth's surface fixed to a specific location and hence it is sometimes known as a local tangent or local geodetic plane. In an airplane, most objects of interest are below the aircraft, so it is sensible to define down as a positive number.

Answer: A) Latitude. Explanation: Latitude comes first among latitude or longitude. Latitude is written before longitude. The first number is always the latitude and the second is the longitude. Latitude is written with a number, followed by either “north” or “south” depending on whether it is located north or south of the equator. May 13, · Traditionally latitude goes first. Probably it is because latitude measuring techniques were invented much earlier than longitude. See the link Latitude and Longitude. While longitude evaluation had been worked out with accuratecy in ancient world, the issues of longitude measuring were not precise enough. It does not matter whether you look at the lines of latitude or longitude first. Usually coordinates are written latitude, then longitude. Good luck!
Click to see full answer Just so, what are the two lines of latitude called? These lines are known as parallels. A circle of latitude is an imaginary ring linking all points sharing a parallel.
The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator. Secondly, what is the difference between latitude and longitude? Latitude vs.
The latitude specifies a location's distance north or south of the equator. The longitude specifies the location's distance east or west from an imaginary line connecting the North and South Poles, called the Prime Meridian.
Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around the Earth vertically up and down and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arcdegree of longitude. Zero degrees latitude is the line designating the Equator and divides the Earth into two equal hemispheres north and south.
Zero degrees longitude is an imaginary line known as the Prime Meridian. The Equator, Tropics, and Prime Meridian.
Four of the most significant imaginary lines running across the surface of Earth are the equator, the Tropic of Cancer, the Tropic of Capricorn, and the Prime Meridian.
The Equator. The Tropic of Cancer and the Tropic of Capricorn. Prime Meridian. Lines of latitude measure north-south position between the poles. The equator is defined as 0 degrees, the North Pole is 90 degrees north, and the South Pole is 90 degrees south. Lines of latitude are all parallel to each other, thus they are often referred to as parallels.
Terms in this set 7 North Pole. Arctic Circle. Tropic of Cancer. Tropic of Capricorn. Longitude is the angular distance of a place east or west of the meridian at Greenwich, England. For example , New York and Miami have almost exactly the same longitudes : around 80 degrees west. Berlin on the other hand has a longitude of 13 degrees east. Beijing, China, has a longitude of degrees east.
Each great circle passing through the north and south poles has the earth's axis as its diameter. Each great circle is divided by the poles into two semi-circles called meridians of longitude. As the meridians run north and south, places having the same longitude will be due or due south of each other. Rainfall is very high away from cold ocean current upwelling zones, from 2, to 3, mm to in per year. It's an imaginary line that divides the earth into eastern and western hemisphere.
Latitude is written before longitude. The number of latitude degrees will be larger the further away from the equator the place is located, all the way up to 90 degrees latitude at the poles. Vertical mapping lines on Earth are lines of longitude , known as "meridians". Lines of longitude , called meridians, run in a north-south direction from pole to pole.
Longitude is the angular measurement of a place east or west of the prime meridian. English Language Learners Definition of longitude : distance measured in degrees east or west from an imaginary line called the prime meridian that goes from the North Pole to the South Pole and that passes through Greenwich, England.
The easiest way to remember the difference between latitude and longitude is by associating the terms with different parts of a ladder. Lines of latitude run east and west. To remember , think of the rungs of a ladder which sounds somewhat similar to latitude which run across, connecting the two longer pieces. In , the International Meridian Conference took place to establish an internationally recognised single meridian. The meridian chosen was that which passed through the Airy transit circle at Greenwich and it became the prime meridian.
Use the sight line on the top of the aiming beam to align the beam with the North Star. This angle is your latitude. What are latitude and longitude lines also called? Category: science geography. Imaginary lines running horizontally around the globe.
Also called parallels, latitude lines are equidistant from each other. Unlike latitude lines , longitude lines are not parallel. Meridians meet at the poles and are widest apart at the equator.
