Geodetic Control
Geodetic control surveys are usually performed to establish a
basic control network from which supplemental surveying and mapping
work is performed. Geodetic network surveys are distinguished by use
of redundant, interconnected, permanently monumented control points
that comprise the framework for the National Spatial Reference
System (NSRS).
These surveys must be performed to far more rigorous accuracy and
quality assurance standards than those for control surveys for
general engineering, construction, or small scale topographic
mapping purposes. Geodetic network surveys included in NSRS must be
performed to meet automated data recording, submittal, project
review, and least squares adjustment requirements established by the
National Geodetic Survey (NGS).
Coleman and Associates has been working to establish a Geodetic
control network in Denton County, Texas. With the addition of a
permanent fixed Global Positioning System (G.P.S) receiver mounted
to the roof of the building. We also have established many geodetic
control networks across our work area and have many Online
Positioning User Service (O.P.U.S.) corrected control points
throughout our network .
