The total system formed by the intersecting network of parallels of latitude and meridians of longitude on a map or globe is called a geographic grid. This grid allows for the precise location of any point on the Earth’s surface using geographic coordinates (latitude and longitude).
The network formed by parallels (lines of latitude) and meridians (lines of longitude) is known as the geographic grid.
Parallels run east-west and measure distance north or south of the equator (latitude). Meridians run north-south from pole to pole and measure distance east or west of the Prime Meridian (longitude).
