21-56.1608. CLASSIFICATION LAND INFORMATION SYSTEM/GEOGRAPHIC INFORMATION SYSTEM SURVEYS

(a) General: Land Information System/Geographic Information System (LIS/GIS) surveys are defined as the measurement of existing surface and subsurface feature's for the purpose of determining their accurate geospatial location for inclusion in an LIS/GIS database. All LIS/GIS surveys as they relate to property lines, rights-of-way, easements, subdivisions of land, the position for any survey monument or reference point, the determination Of the configuration or contour of the earth's surface or the position of fixed objects thereon, and geodetic surveying which includes surveying for determination of the size and shape of the earth both horizontally and vertically and the precise positioning of points on the earth utilizing angular and linear measurements through spatially oriented spherical geometry, shall be performed by a Land Surveyor who is a registrant of this Board. For the purpose of specifying minimum allowable surveying standards, three general classifications of LIS/GIS surveys are established: (1) Urban and Suburban LIS/GIS surveys (Class A). Urban and suburban LIS/GIS surveys include the location of features within lands which lie in or adjoining a town or city. For Class A LIS/GIS surveys in North Carolina, the relative accuracy shall be equal to or less than 0.5 meter (1.64 feet). (2) Rural LIS/GIS surveys (Class B). Rural LIS/GIS surveys include the location of features within lands which lie outside of suburban areas. For Class B LIS/GIS surveys in North Carolina, the relative accuracy shall be equal to or less than 2 meters (6.56 feet). (3) Regional LIS/GIS surveys (Class C). Regional LIS/GIS surveys include the location of features within lands which lie in multi-county areas. For Class C LIS/GIS surveys in North Carolina, the relative accuracy shall be equal to or less than 5 meters (16.40 feet). (b) Nothing in this Section shall be construed to negate or replace the relative accuracy standards found in Rules .1601 through .1607. (c) The Professional Land Surveyor in responsible charge of the LIS/GIS boundary or geodetic control survey shall certify to all of the following in either written or digital form: (1) Class of LIS/GIS survey, (2) Method of measurement (i.e. global positioning system, theodolite and electronic distance meter, transit and tape), (3) Date(s) of the survey, (4) Datum used for the survey.
