PSC 121 Prince George’s Community College Barbara Gage Coordinate Systems On a sphere such as the Earth, we can pinpoint the location of any city or landmark using two values, the lines of latitude and longitude.

PSC 121 Prince George’s Community College Barbara Gage On the Earth there are two additional sets of reference points. On the Earth there are two additional sets of reference points. The Equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere. The Equator divides the Earth into the Northern Hemisphere and the Southern Hemisphere.

PSC 121 Prince George’s Community College Barbara Gage The Prime Meridian divides the Earth into the Western Hemisphere and the Eastern Hemisphere.

PSC 121 Prince George’s Community College Barbara Gage Latitude Latitude is defined as the location point above (or below) the equator. Latitude is defined as the location point above (or below) the equator. The measurement is expressed in degrees, minutes, and seconds. The measurement is expressed in degrees, minutes, and seconds. The equator is at 0° and the poles are at 90°. The equator is at 0° and the poles are at 90°.

PSC 121 Prince George’s Community College Barbara Gage Latitude If the location point is north of the equator an N is added to the degrees. If the location point is north of the equator an N is added to the degrees. If the point is to the south of the equator an S is added to the value. If the point is to the south of the equator an S is added to the value. 52°N 24°S

PSC 121 Prince George’s Community College Barbara Gage Longitude Longitude is defined as the measurement of the location point east or west of the Prime Meridian Longitude is defined as the measurement of the location point east or west of the Prime Meridian The value is also expressed in degrees, minutes, and seconds. The value is also expressed in degrees, minutes, and seconds. Note: There are 60 minutes in a degree and 60 seconds in a minute.

PSC 121 Prince George’s Community College Barbara Gage Longitude If the point is located to the west of the Prime Meridian we add a W to the value. If the point is located to the west of the Prime Meridian we add a W to the value. If the point is located east of the Prime Meridian we add an E after the value If the point is located east of the Prime Meridian we add an E after the value 30°W 80°E
