GPS to aid in construction of roads

The Glynn County GIS has begun installing 26 new survey controlled monuments in Brunswick and on St. Simons Island to aid in the construction of roads and sewer systems. The monuments, which are buried in the ground, are small and circular in diameter with a brass disc located inside to determine precise latitude and longitude coordinates and elevations.

The monuments are registered with the National Geodetic Survey Agency. In addition to benefiting surveyors, the project will lead to better road construction and flood-control.These monuments are unique in comparison to the traditional monuments as they are being used with a GPS that allows them to collect data from satellites, which gives it better accuracy.
