Section 50:1 - DefinitionsThe terms defined in this Section have the following meaning when found in this Chapter:
(1) "Deprecation" means a decision to discontinue the use of a specific unit or method of measurement.(2) "Geodetic coordinate" means angular coordinates defined relative to a particular geodetic datum, including, but not limited to, latitude, longitude, ellipsoid height, orthometric height, or dynamic height(3) "Geodetic datum" means the geometric models representing the earth's size and shape that provide abstract coordinate systems with a reference surface or origin and orientation that serves to provide known locations to begin surveys and create maps; also referred to as a terrestrial reference frame or reference frame.(4) "International Foot" means the length adopted in 1959 to define the unit of measurement equal to 3,048/10,000 meter.(5) "Meter" means the length traveled by light in a vacuum during a time interval of exactly 1/299,792,458 seconds.(6) "National Spatial Reference System" means the consistent coordinate system maintained by the National Geodetic Survey that defines latitude, longitude, height, scale, gravity, and orientation throughout the United States, including an accurate national shoreline; a set of models that describes geophysical processes that affect spatial measurements; and networks of permanently marked points and continuously operating reference stations (CORS) to support three-dimensional positioning activities.(7) "NATRF2022" means the North American Terrestrial Reference Frame of 2022.(8) "State plane coordinate system" means the system of conformal map projections created by the National Geodetic Survey to support surveying, engineering, and mapping activities throughout the United States.(9) "U.S. survey foot" means the length adopted by the United States government in 1893 to define the unit of measurement equal to 1,200/3,937 meter.(10) "Zone" means a geographic region on the surface of the earth with a uniquely defined projected coordinate reference system, with extents usually based on a specified maximum linear distortion magnitude.
