from JROTC.Org LATITUDE & LONGITUDE |
In the Earth's reference system, the lines that run: east and west are called parallels of latitude because they are parallel with the equator. Each of these parallel lines forms a circle on the face of the earth. Each one is a constant distance north or south of the equator. the equator is latitude 0 degrees and the poles are located at 90 degrees latitude. |
Lines running north and south, passing through the North and South poles, are called meridians of longitude. Meridians run perpendicular to the equator. The starting point, or 0 degree meridian, is the one passing through Greenwich, England. It is called the prime meridian. the prime meridian serves as the starting point of east-west measurement. |
