how to read latitude longitude
Latitude is angular distance measured north and south of the Equator. The Equator is 0 degrees. As you go north of the equator the Latitude increases all the way up to 90 degrees at the north pole. If you go south of the equator, the Latitude increases all the way up to 90 degrees at the south pole.
Geographic coordinate system. Longitude lines are perpendicular to and latitude lines are parallel to the equator. A geographic coordinate system is a coordinate system used in geography that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position, and two or three of the numbers represent a horizontal position.
