To precisely locate any point on the Earth’s surface on a 2D map, you need a system of coordinates. The most common system uses latitude and longitude. Latitude measures the angular distance north or south of the equator, and longitude measures the angular distance east or west of the Prime Meridian. The intersection of a specific latitude and a specific longitude provides a unique location on the map. Altitude (height above sea level) describes the vertical position and is not needed to locate a point horizontally on a standard map.
