A system to locate points on the Earth's surface. A geographic coordinate system (GCS) is a coordinate system associated with positions on Earth (geographic position). 41° 27' 41'' N) means 41° north plus 27/60 of a degree plus 41/3600 of a degree. A minute is 1/60 of a degree, and a second is 1/60 of a minute, or 1/3600 of a degree. Meridians are identified by longitude, which is an angular measure of how far eastward or westward the meridian is from a reference meridian, called the prime meridian. Relative location is the location of something relative to other entities. We label parallels and meridians by their latitude and longitude. //]]>. Many cities within the United States were designed using a grid system. Imagine cutting the globe just as you might slice an onion to make onion rings (Figure 1.4 A).

It is an established tool that is used by print and web designers to create well-structured, balanced designs. This arrangement is called a grid reference system, and every point on the flat map can be located with a unique X and Y coordinate. Log in. Latitude and longitude form our coordinate system grid. All parallels in the northern hemisphere are described by a north latitude, and all parallels south of the Equator are given as south latitude (N or S). Longitude lines are perpendicular to and latitude lines are parallel to the Equator. A degree of latitude, which measures distance in a north-south direction, is equal to about 111 km (69 mi). Log in. Geographic Grid System Geography is about spatial understanding, which requires an accurate grid system to determine absolute and relative location. home:: earth:: geography:: cartography:: grid system grid system Collective term for the parallels and meridians that form an imaginary grid over the Earth’s surface, … Regardless of how old we are, we never stop learning. 1. grid in Geography topic. The position of the point is defined by their intersection. When you put two coordinates together as a pair (X, Y), you can locate anything on Earth. Each cut creates a circular outline that passes around the surface of the globe. This is made up of a system of imaginary circles, called parallels and meridians, which are shown in Figure 1.4.

As we will see shortly in our discussion of map projections, the portion of the great circle between two points is the shortest distance between them. Longitude then ranges from 0° to 180°, east or west (E or W). Indeed, that is why a Greek named Hipparchus invented the global grid some 2,200 years ago. A freelance writer since 2010, Miller enjoys gaining valuable experience and growing as a writer. We use the Equator as a fundamental reference line for measuring position. Instead, we divide the Earth into what is known as the geographic grid. The Earth's longest parallel of latitude is the Equator , which lies midway between the two poles. (Much like the system used to locate a postal address - where two co-ordinates are used, the main street and the cross street.) Join now.
