As an illustration, consider an example where two new inter-
visible points are to be established on a project site for use as
control for a boundary survey. The two new points need to be
tied to an existing control point 3 kilometers (1.9 miles) away.
If you were to perform this survey with a conventional total sta-
tion, you would probably plan on running a closed-loop
traverse from the existing control point through the two new
points (see figure below). The same philosophy can be used
for GPS surveys. The figure below is your network design for
this survey
