Surveying with the ProMark2 System
This chapter presents step-by-step procedures for performing a GPS survey with the ProMark2
system. Review this chapter thoroughly before attempting to perform your first survey. As an
exercise, take your system outside of your office and perform a sample survey following the
procedures outlined below. Then download and process the collected data with Ashtech
Solutions. After this exercise, you will be ready to perform your first real survey with the
ProMark2 system.
Static Survey Planning
Prior to venturing out into the field, you must first plan how you will execute your static
survey. Proper planning will greatly increase the chances of success. There are two primary
areas of static survey planning, the
network design
and
observation plan
. Each is discussed
below.
Network Design
You have identified a survey for which you wish to use the ProMark2 system to establish
control. Regardless if the number of control points to be established is 2 or 20, you must
design a network defining the number and location of observations (vectors in our case) that
will be required to effectively position the new points.
As an illustration, consider an example where two new intervisible 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, Figure 3.1
