	Geographic coordinate system - Wikipedia, the free encyclopedia
		A geographic coordinate system expresses every location on Earth by two of the three coordinates of a spherical coordinate system which is aligned with the spin axis of Earth.
		Borrowing from theories of ancient Babylonians, later expanded by the famous Greek thinker and geographer Ptolemy, a full circle is assigned 360 degrees (360°).
		The equator is obviously an important part of this coordinate system, it represents the zeropoint of the latitude angle, and the halfway point between the poles.

	Geographic coordinate conversion - Wikipedia, the free encyclopedia
		Depending on which type of coordinate you are provided with, and which type you would like to work with, you may have to do some conversion.
		Given a decimal longitudinal coordinate such as -87.728055 it is trivial to convert it to DMS form.
		A coordinate with at 0°0'0" latitude or longitude is neither North nor South, East nor West.

	Coordinate system - Facts, Information, and Encyclopedia Reference article
		Changing the basis is a coordinate transformation, a linear transformation that can be summarized by a matrix, and is computationally the same as a mapping of points to other points keeping the bases the same: e.g.
		Curvilinear coordinates are a generalization of coordinate systems generally; the system is based on the intersection of curves.
		Intrinsic coordinates describe a point upon a curve by the length of the curve to that point and the angle the tangent to that point makes with the x-axis.

	Geographic Coordinate System Transformations
		The transformations may be most readily achieved by first expressing the observed or source geographical coordinates in terms of three dimensional XYZ cartesian values (geocentric coordinates) instead of the normal angular expressions of latitude and longitude.
		One such application is the coordinate transformation introduced to enable the conversion of coordinates expressed in the North American Datum of 1927 (including the Clarke 1866 ellipsoid) to coordinates expressed in the new North American Datum of 1983 which takes the GRS 1980 ellipsoid.
		Because the coordinate differences are small and the coordinates in the source and target systems are very similar in magnitude, in reversible polynomial transformations it is possible to adopt the same coordinate values for the evaluation point in both source and target systems.

	Coordinate Systems
		Geographic information systems are information systems that permit complex associations to be made between entities using geometric references.
		In a coordinate system, many differences are permitted to vary at the same time ('co' having a root meaning along the lines of 'with', and 'ordinate' implying something to do with placement or measurement in some sort of scale.) The incremental change that a coordinate system records are the units of measure.
		When transforming coordinate systems it is important to think about transformation the way we think about other associative functions in information systems -- that is we are trying to define a function that simulates the actual distortion of the geometry in the unknown system.

		If the output coordinate reference frame has any parameters associated with it (e.g., a central meridian), and the default parameter values displayed in the lower half of the window are not the desired values, change the parameter values by selecting the displayed values and typing over them.

	The Ultimate Latitude Dog Breeds Information Guide and Reference
		Lines of latitude other than the Equator are approximately small circles on the surface of the Earth; they are not geodesics since the shortest route between two points at the same latitude involves moving farther away from the equator.
		In common usage "latitude" refers to geodetic or geographic latitude φ and is the angle between a plumb line and the equatorial plane — because it originated as the angle between horizon and pole star.
		For other planets such as Mars, geographic and geocentric latitude are called "planetographic" and "planetocentric" latitude, respectively.

	Reference.com/Encyclopedia/Latitude
		Because the Earth is slightly flattened by its rotation, cartographers refer to a variety of auxiliary latitudes to precisely adapt spherical projections according to their purpose.
		More generally, for other planets such as Mars, geographic and geocentric latitude are called "planetographic" and "planetocentric" latitude, respectively.
		In common usage, "latitude" refers to geodetic or geographic latitude φ and is the angle between the equatorial plane and a line that is normal to the reference spheroid, which approximates the shape of the Earth to account for flattening of the poles and bulging of the equator.

		The coordinates will automatically be displayed, but the name of the coordinate, such as the name of the intersecting roads, will need to be entered.
		To register the coordinate, first zoom in as tight as possible on the area to register on the drawn map (the road or waterway intersection).
		Once the coordinates are registered on the unreferenced map, the map may disappear from the screen.

		The geographic area for which this conversion will work is bounded on the east by longitude 73° 37' 30" and on the west by 75° 37" 30".
		Thus, the SPCS is a rectangular (x,y or northing, easting) coordinate system describing geodetic positions of a limited area (a state or a portion of it) on a plane.
		The (x,y) coordinates are computed by projecting latitudes and longitudes from a mathematical approximation of the earth (i.e., NAD83) onto a rectangular grid.
