The change law of latitude is that the equator (0 degrees latitude) increases to the South and North poles. The greatest latitude is 90 degrees, at the South Pole and the North pole. The north of the equator latitude is called latitude, with "N"; south of the equator latitude is called...
There are 90 degrees of south latitude.In the Northern Hemisphere there is a star called Polaris almost directly over the North Pole. This makes it possible to determine the latitude of a given point by setting our sextant(六分仪) to measure the angle between Polaris, the North Star, and ...
Latitude lines are given numbers in degrees between 0 degrees at the Equator, and 90 degrees north at the North Pole, and from 0 degrees at the Equator to 90 degrees south at the South Pole. This separates the Northern Hemisphere and the Southern Hemisphere. Latitude lines are called ...
The 180th degree meridian is also called the anti meridian. It is used to define the International Date Line. Because the Earth is spherical, traveling 180 degrees in either direction from the prime meridian will lead to 180 degrees longitude or the opposite meridian. The 180-degree meridian ...
degrees (°), which may be broken down into smaller units called minutes (′) and seconds (″). (Or they may be expressed in decimal degrees; negative values of decimal degrees represent latitudes in the Southern Hemisphere and longitudes in the Western Hemisphere.) The latitudes of the ...
Lines of latitude are called parallels and in total there are 180 degrees of latitude. The distance between each degree of latitude is about 69 miles (110 kilometers). ► (Watch this video on YouTube: Latitude and Longitude) What is a Parallel? A parallel is a named line connecting al...
Two angles, latitude and longitude, specify the position of a point on the surface of a planet. The most common angular units are degrees and radians. Most Mapping Toolbox™ functions perform angle computations in degrees. Thelatitudeof a point is the angle between the plane of the equator...
in hours, minutes and seconds, with values ranging from 0 to 24 hours. Longitude runs both eastward and westward and is measured in degrees, with a value of zero at Greenwich up to -180 degrees westerly and +180 degrees easterly. The 180-degree line is called the International Date Line...
Since a sphere has 360 degrees, the Earth is divided into 360 longitudes. The meridian opposite the Prime Meridian (on the other side of the Earth) is the 180° longitude and is known as theantimeridian. Modern timekeeping systems use longitudes as references to keep time.Time zonesare def...
meridian is the imaginary north-south line that passes through the north and south poles, as well as Greenwich. It has a longitude of 0 degrees. The antemeridian, which is the opposite of the prime meridian, is located on the other side of the Earth and has a longitude of 180 degrees....
