It was established by president Thomas Jefferson in 1807 as the Survey of The Coast. Geodetic Monitoring is the study of the geometry of the earth and at the same time developing methods and techniques using space technology to monitor them. The geodetic survey was directed by Assoc.

The Survey is based on a network of triangles of which the first was located on the shores of Long Island with one side of the triangle consisting of a carefully measured baseline. The geodetic survey is the survey of a very large area in which the curvature of the earths surface is studied and if needed it is then corrected. Because of problems in that adjustment and with the growing use of satellite geodesy the North American Datum of.

If used judiciously with geotechnical instrumentation geodetic monitoring provides co-related data which is relevant and extensively used in civil construction and structural monitoring. Geodetic Surveying began in the United States in February 10th 1807. During the late 1950s Geodimeter introduced electronic distance measurement EDM equipment.

Triangulation is the most common of all geodetic survey techniques and requires very accurate. As far back as 1817 the Survey of the Coast began determining elevations in coastal areas using trigonometric methods. The National Geodetic Survey our Nations first civilian scientific agency was established by President Thomas Jefferson in 1807 as the Survey of the Coast.

Geodetic leveling seems to have been started by the US. Thus geodetic surveying began. In geodetic surveying highly refined instruments and methods are used.

History in Koç University directed the architectural and historic research. The history of surveying and measurement has been part of FIG work since its estab-lishment more than 130 years ago. The need for maps and location of national boundaries caused England and France to make extensive surveys requiring accurate triangulation.

Accurate models of storm surge and pollution highway planning effective resource management and adequate disaster preparedness all require accurate elevations. The aim of geodetic surveying was to survey the United States coastline. Coast and Geodetic Survey was established by an act of Congress in 1807.

Coast and Geodetic Survey now the National Geodetic Survey selected the Clarke 1866 ellipsoid because it was the best-fit surface for the US.

This is natural because of the role of surveying map-ping and exploring the globe since beginning of mankind. Coast Survey in 1856 along the Hudson River. In 1927 the US.

Astronomic Observations are achieved through theodolites zenith cameras and prismatic astrolabes. In the 18th and 19th centuries the art of surveying advanced more rapidly. Positions with other survey data triangulation and trilateration geodesists are able to establish precise positions and locations of places and objects.

Its purpose was to link the Greenwich and Paris observatories. Four traditional surveying techniques 1 astronomic positioning 2 triangulation 3 trilateration and 4 traverse are in general use for determining the exact positions of points on the earths surface. Its mission was and still is to survey the US.
