Principles of Cartography and Photo Identification
Location Coordinates
Geographic Coordinates
Latitude
The angular distance measured from the equator to a given point
Length
It is the angular distance measured from the reference meridian (usually the Greenwich meridian) to a given point
UTM (Universal Transverse Mercator) coordinates
