the instructions below to select the proper base point for
your first GPS base.
Select Base Point
5. The user interface shown on the Select Base Point page
will depend on the location of the base setup and whether
or not any GPS points or a GPS coordinate system exists
yet in the job. Before showing the Select Base Point
screen, Survey Pro will search the job for a point that
matches the location of the base. One of three screens
will show:
• When Survey Pro can not match the base location to
any point in the job file, the Select Base Point page
allows you to specify if the base is setup on an existing
job point, or if you are creating a new job point with
the base setup. You will always see this screen for the
first GPS setup in a job without a coordinate system.
You will also see this screen if you set the base on a
new location in a job that already has a coordinate
system. Select the radio button for either new or
known point, and enter the Base Point name in the
edit field.
• When Survey Pro finds a unique point in the job file
that matches the base location, the Select Base Point
page shows you the name of the base point found.
• When Survey Pro finds more than one point in the job
file that matches the base location, the Select Base
Point page has a drop down list of possible matches
for you to choose from.
Note: When one or more matching points are found in the job
file, you can revert to the new or existing point user interface
by tapping Change on the Select Base Point screen.
6. Review the choice of base point on the Select Base Point
page. Tap Next > to finish the base receiver setup and
proceed to rover setup. Connect to the rover receiver
when prompted to do so.
