Geographic coordinate system MapCentral Base
Name of the geographic coordinate system (or datum), not to be confused with projected coordinate systems. Grid systems vary, but the most common is a square grid with grid lines numbered sequentially from the origin at the bottom left of the map. The grid numbers on the east-west (horizontal) axis...

x Regular grid      
A regular grid is a tessellation of the Euclidean plane by congruent rectangles or a space-filling tessellation of rectilinear parallelepipeds (e.g. bricks). Grids of this type appear on graph paper and may be used in finite element analysis as well...
x North American Datum of 1983   GRS 80 Kentucky Single Zone Coordinate System of 1983
As satellite and remote sensing technology both improved and were made available for civilian applications, it became obvious that the NAD-27's appromixations were not sufficiently accurate. The North American Datum of 1983 was created to meet...

x North American Datum of 1927   Clarke 1866  
The North American Datum is the official datum used for the primary geodetic network in North America. In the fields of cartography and land-use there are currently two North American Datums in use: the North American Datum of 1927 (NAD27) and the...
