What is the precursor to the national geodetic survey?

The United States Coast and Geodetic Survey is recognized as the precursor to the National Geodetic Survey. Established in the 19th century, this agency was responsible for surveying the nation's coastlines and establishing geodetic control networks, which are foundational for map-making and navigation. The work performed by the Coast and Geodetic Survey laid the groundwork for the geodetic framework that is essential for modern surveying and mapping activities.

Following its evolution, the functions of the Coast and Geodetic Survey eventually led to the establishment of the National Geodetic Survey, which continues to provide critical geospatial infrastructure for the United States. Understanding this historical context showcases the significance of the Coast and Geodetic Survey’s role in the development of geodetic science and the establishment of standards for surveying methods.
