Longitude is measurement east or west of the Prime Meridian in degrees, minutes, and seconds.

Explanation:
Longitude defines the angular distance east or west of the Prime Meridian, measured in degrees, minutes, and seconds (or decimal degrees). The Prime Meridian runs through Greenwich, and lines of longitude are established as great circles that converge at the poles, establishing a global east–west reference frame. This is different from latitude, which measures north–south position relative to the Equator; altitude, which is height above the Earth's surface; and bearing, which is the direction you would travel relative to north rather than a coordinate of a location. So the statement describes longitude exactly.
