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.
The horizontal coordinate system is a celestial coordinate system that uses the observer's local horizon as the fundamental plane to define two angles of a spherical coordinate system: altitude and azimuth. Therefore, the horizontal coordinate system is sometimes called the az/el system, [1] the alt/az system, or the alt-azimuth system, among
Module:Location map/data/USA North Carolina is a location map definition used to overlay markers and labels on an equirectangular projection map of North Carolina. The markers are placed by latitude and longitude coordinates on the default map or a similar map image.
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 ...
The azimuth is the angle formed between a reference direction (in this example north) and a line from the observer to a point of interest projected on the same plane as the reference direction orthogonal to the zenith. An azimuth (/ ˈ æ z ə m ə θ / ⓘ; from Arabic: اَلسُّمُوت, romanized: as-sumūt, lit.
A geodetic datum or geodetic system (also: geodetic reference datum, geodetic reference system, or geodetic reference frame, or terrestrial reference frame) is a global datum reference or reference frame for unambiguously representing the position of locations on Earth by means of either geodetic coordinates (and related vertical coordinates) or geocentric coordinates.

The North Carolina state House map passed by the General Assembly on Oct. 25, 2023, to use in the 2024 elections. Changes to NC congressional districts for 2024.
Local tangent plane coordinates (LTP) are part of a spatial reference system based on the tangent plane defined by the local vertical direction and the Earth's axis of rotation. They are also known as local ellipsoidal system, [1] [2] local geodetic coordinate system, [3] local vertical, local horizontal coordinates (LVLH), or topocentric ...
