| Description: The latitude_type attribute defines the type of latitude (planetographic, planetocentric) used within a cartographic product and as reflected in attribute values within associated PDS labels. For planets and satellites, latitude is measured north and south of the equator; north latitudes are designated as positive. The planetocentric latitude is the angle between the equatorial plane and a line from the center of the body. The planetographic latitude is the angle between the equatorial plane and a line that is normal to the body. In summary, both latitudes are equivalent on a sphere (i.e., equatorial radius equal to polar radius); however, they differ on an ellipsoid (e.g., Mars, Earth).
