This data contains a set of geodetic control stations maintained by the National Geodetic Survey in the state of Rhode Island. Each geodetic control station in this dataset has either a precise Latitude/Longitude used for horizontal control or a precise Orthometric Height used for vertical control, or both. This dataset represents all geodetic control stations throughout the state of Rhode Island. The National Geodetic Survey (NGS) serves as the Nation's depository for geodetic data. The NGS distributes geodetic data worldwide to a variety of users. These geodetic data include the final results of geodetic surveys, software programs to format, compute, verify, and adjust original survey observations or to convert values from one geodetic datum to another, and publications that describe how to obtain and use Geodetic Data products and services.

These data provide a base of reference for latitude, longitude and height throughout the Rhode Island.
