Thus the state plane coordinate system is still useful. Originally, the state plane coordinate systems were based on the North American Datum of 1927 (NAD27). Later, the more accurate North American Datum of 1983 (NAD83) became the standard (a geodetic datum is the way a coordinate system is linked to the physical Earth). More recently there ...
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.
Each state has its own set of reference parameters given in the standard. [8] The U.S. National Geodetic Survey's "State Plane Coordinate System of 1983" uses the Lambert conformal conic projection to define the grid-coordinate systems used in several states, primarily those that are elongated west to east such as Tennessee.
During the American Civil War, the Confederate States of America consisted of the southeastern states of Florida, Alabama, Georgia, Mississippi, Tennessee, South Carolina, North Carolina, Virginia, Louisiana, and Arkansas. Texas was a Confederate State that isn't defined as

Grid Zone Designation (GZD); for a world-wide unique address. This consists of up to 2 digits (6-degree longitude UTM zone) for West to East, followed by a letter (8-degree latitude band) from South to North; in this example, "18S".

The rivers of central North Carolina rise on the eastern slopes of the Blue Ridge. The two largest of these are the Catawba River and the Yadkin River, and they drain much of the Piedmont region of the state. The major rivers of Eastern North Carolina, from north to south, are: the Chowan, the Roanoke, the Tar, the Neuse and the Cape Fear.
