The settlement of Mason grew up around Fort Mason, which was established by the United States War Department as a front-line defense against Kiowa, Lipan Apache, and Comanche, on July 6, 1851. George W. Todd established a Fort Mason post office March 8, 1858, which became consigned to the civilian settlement on June 26, 1858. [6]
The 33rd parallel north is a circle of latitude that is 33 degrees north of the Earth's equatorial plane. It is approximate at the midpoint between the equator (0 degrees) and the Arctic Circle (66.6 degrees North Latitude.) It crosses North Africa, Asia, the Pacific Ocean, North America and the Atlantic Ocean.
Module:Location map/data/USA Texas is a location map definition used to overlay markers and labels on an equirectangular projection map of Texas. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
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.
The Mason–Dixon line – another line linked to the slave-free division in the U.S. Royal Colonial Boundary of 1665 – the border between the Colony of Virginia and the Province of Carolina that follows the parallel 36°30′ north latitude that came to be associated with the Missouri Compromise of 1820.

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).
In other words, it is a coordinate line for longitudes, a line of longitude. The position of a point along the meridian at a given longitude is given by its latitude, measured in angular degrees north or south of the Equator. On a Mercator projection or on a Gall-Peters projection, each meridian is perpendicular to all circles of latitude.
