The South Carolina Legislative Council is offering access to the unannotated South Carolina Code of Laws on the Internet as a service to the public. The unannotated South Carolina Code on the General Assembly's website is now current through the 2010 session. The unannotated South Carolina Code, consisting only of Code text and numbering, may be copied from this website at the reader's expense and effort without need for permission.
The Legislative Council is unable to assist users of this service with legal questions. Also, legislative staff cannot respond to requests for legal advice or the application of the law to specific facts. Therefore, to understand and protect your legal rights, you should consult your own private lawyer regarding all legal questions.
While every effort was made to ensure the accuracy and completeness of the unannotated South Carolina Code available on the South Carolina General Assembly's website, the unannotated South Carolina Code is not official, and the state agencies preparing this website and the General Assembly are not responsible for any errors or omissions which may occur in these files. Only the current published volumes of the South Carolina Code of Laws Annotated and any pertinent acts and joint resolutions contain the official version.
Please note that the Legislative Council is not able to respond to individual inquiries regarding research or the features, format, or use of this website. However, you may notify Legislative Printing, Information and Technology Systems at LPITS@scstatehouse.gov regarding any apparent errors or omissions in content of Code sections on this website, in which case LPITS will relay the information to appropriate staff members of the South Carolina Legislative Council for investigation.
Title 27 - Property and Conveyances
COORDINATE SYSTEM FOR DEFINING LOCATION OF POINTS WITHIN STATE
System adopted; title.
The system of plane coordinates which has been established by the National Ocean Survey and the National Geodetic Survey for defining and stating the positions or location of points on the surface of the earth within this State may be cited as the "South Carolina Coordinate System Act."
For the purpose of the use of this system the State is designated as one zone.
Zone title for use in land descriptions.
As established, the South Carolina Coordinate System is named, and in a land description in which it is used it is designated, the "South Carolina Coordinate System."
Plane coordinates for expressing position of point defined.
The plane coordinates of a point on the earth's surface, to be used in expressing the position or location of a point in the State, consist of two distances, expressed in feet and decimals of a foot. One of these distances, to be known as the easting (x-coordinate), gives the distance in an east-and-west direction; the other, to be known as the northing (y-coordinate), gives the distance in a north-and-south direction. These coordinates must be made to depend upon and conform to the coordinates, on the South Carolina Coordinate System, of the monumented points of the North American Horizontal Geodetic Control Network as published by the United States Coast and Geodetic Survey (now the National Geodetic Survey) within this State as those coordinates have been determined by the survey.
Coordinate System defined.
For purposes of more precisely defining the South Carolina Coordinate System, the following definition by the National Ocean Survey and the National Geodetic Survey is adopted:
The South Carolina Coordinate System is a Lambert conformal projection of the North American Datum, 1983, having standard parallels at north latitudes 32° 30' and 34° 50', along which parallels the scale must be exact. The origin of coordinates is at the intersection of the meridian 81° 00'west of Greenwich and the parallel 31° 50' north latitude. This origin is given the coordinates: * = 2,000,000 feet and y = 0 feet. For the purposes of the South Carolina Coordinate System, the foot is the International Foot with one inch being exactly equal to 2.54 centimeters.
The position of South Carolina Coordinate System is as marked on the ground by monumented points of the North American Horizontal Geodetic Control Network established in conformity with standards adopted by the Federal Geodetic Control Committee for first-order and second-order work, whose geodetic positions have been rigidly adjusted on the North American Datum of 1983, and whose coordinates have been computed on the system defined in this section. Any such stations may be used for establishing a survey connection with the South Carolina Coordinate System.
Standards required for recordation; modification to meet local conditions.
No coordinates based on the South Carolina Coordinate System, purporting to define the position of a point on a land boundary, may be presented to be recorded in public land records or deed records unless that point is established in accordance with Federal Geodetic Control Committee specification for second order-class two. The limitation may be modified by the South Carolina Geodetic Survey to meet local conditions.
Use of term "South Carolina Coordinate System" on map.
The use of "South Carolina Coordinate System" on a map, report of survey, or other document, must be limited to coordinates based on the South Carolina Coordinate System as defined in this chapter.
Duties of South Carolina Geodetic Survey.
The South Carolina Geodetic Survey established within the Division of Research and Statistical Services of the Budget and Control Board shall establish horizontal and vertical geodetic control within the State at a density that effectively will provide land and land-related items and records to be referenced to the national horizontal and vertical coordinate system, ensure the accuracy and integrity of new geodetic data entered into the state and national reference system, maintain geodetic files for the State, and disseminate geodetic information as necessary.
State mapping products to be compatible with coordinate system; establishment of standards; programs.
To the extent possible, the South Carolina Geodetic Survey of the Division of Research and Statistical Services of the Budget and Control Board shall utilize the office's responsibility of coordinating mapping activities in the State to ensure that mapping products are compatible with the South Carolina Coordinate System. As part of this activity, the office shall establish, develop, and promulgate standards for maps and map products to ensure quality, accuracy, and compatibility of mapping products, encourage the development of accurate mapping systems that are compatible with and suitable for incorporation into a standardized statewide mapping system, develop, maintain, and administer programs for funding qualified mapping projects, and serve as the focal point for federal, state, and local mapping programs and activities in South Carolina.
Geodetic survey to assist in defining and monumenting county boundaries; mediating boundary disputes.
Where county boundaries are ill-defined, unmarked, or poorly marked, the South Carolina Geodetic Survey on a cooperative basis shall assist counties in defining and monumenting the locations of county boundaries and positioning the monuments using geodetic surveys. The South Carolina Geodetic Survey shall act as a mediator between counties to resolve county boundary disputes.
Reliance on description based on coordinate system not required.
Nothing contained in this chapter requires a purchaser or mortgagee to rely on a description, a part of which depends exclusively upon the South Carolina Coordinate System.
