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 ...
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 r...
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. The latitude of a point is the angle between the plane of the equat...
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...
Lines of longitude are also called "meridians." The International Date Line is 180 degrees east and west of the Prime Meridian. This means it is an equal distance away both east and west of the Prime Meridian and is halfway around the earth from the Prime Meridian. ...
The earth is effectively a sphere, so how do we describe where a point is on its surface?The most common way to locate points on the surface of the Earth is by standard, geographic coordinates called latitude and longitude. These coordinates values are measured in degrees, and represent ...
180° east and 180 degrees west from the prime meridian. InSurfer, longitude is positive east (east longitude) of the prime meridian, and negative west of the prime meridian (west longitude). A designation such as -105° is used to indicate a location 105 degrees west of the prime ...
Longitude value ranges from 0 degrees at the prime meridian to 180 degrees exactly halfway around the globe from the prime meridian. Longitude can be expressed as a positive number followed by an E or W to indicate whether it is to the east or west of the prime meridian, or as a ...
Both latitude and longitude are measured in 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 ...
Lines of longitude (also called meridians) run between the geographic North Pole and the geographic South Pole and are used to measure distances from the prime meridian. Both latitude and longitude are measured in degrees (°), which may be broken down into smaller units called minutes (′) ...
