Longitude and Latitude Imaginary lines that are drawn around Earth to help geographers study location of places. Latitude: Horizontal lines that run EAST to WEST. Latitude is the distance north or south of the Equator, measured in units called degrees. Longitude: Vertical lines that run NORTH to SOUTH. Longitude is the distance east or west of the Prime Meridian, measured in degrees. Philadelphia is located at about 39°N and 75° W on Earth.
