Geodetic survey system is a method created for the purpose of land description and consists of nationwide marks at longitude and latitude points. The geodetic survey system was created by the U.S. government and it integrates most of the real property in the U.S. into one unified form of measurement.
The method is conducted by the National Geodetic Survey (NGS), a federal executive agency. The various functions carried out by the NGS are:
1.Managing a national coordinate system;
2.Providing the foundation for transportation and communication ;
3.Mapping and charting ;
4.Providing a multitude of scientific and engineering applications.
The geodetic survey system was used in establishing a new 1945 boundary line. The 1945 line is a political boundary between the District of Columbia and Virginia. Congress. It provides for geodetic survey in order to suitably mark and establish the 1945 line and from time to time mark any changes in the line. [United States v. Herbert Bryant, Inc., 740 F. Supp. 863, 867-868 (D.D.C. 1990)].
