The 1st parallel north is a circle of latitude that is 1 degree north of the Earth's equatorial plane. It crosses the Atlantic Ocean, Africa, the Indian Ocean, Southeast Asia, the Pacific Ocean, and South America. The parallel defines part of the border between Equatorial Guinea and Gabon. [1]
Primarily from the United States Government Printing Office Style Manual. [1] State names usually signify only parts of each listed state, unless otherwise indicated. Based on the BLM manual's 1973 publication date, and the reference to Clarke's Spheroid of 1866 in section 2-82, coordinates appear to be in the NAD27 datum.
Geodetic latitude and geocentric latitude have different definitions. Geodetic latitude is defined as the angle between the equatorial plane and the surface normal at a point on the ellipsoid, whereas geocentric latitude is defined as the angle between the equatorial plane and a radial line connecting the centre of the ellipsoid to a point on the surface (see figure).
The equator, a circle of latitude that divides a spheroid, such as Earth, into the northern and southern hemispheres. On Earth, it is an imaginary line located at 0 degrees latitude . 0°

In Canadian land surveying, a base line is one of the many principal east-west lines that correspond to four tiers of townships (two tiers north and two south). The base lines are about 24 miles (39 km) apart, with the first base line at the 49th parallel, the western Canada–US border.
