Control File Example

The following general example explains one scenario where a control
file is used. In this example, a new job is created with a point that has
arbitrary coordinates. The control file is selected and used to replace
the arbitrary coordinates with coordinates that are in the same
coordinate system as those in the control file. The steps in this
example can be modified to fit your specific situation.

Assume that you already have a job that contains several known
points for an area where you intend to work. You want to create a
new job and select the existing job as a control file to make the control
points available in the new job. Also, assume that the control file
contains points named

1

through

10

.

1. Create a new job by selecting



)LOH , 2SHQ1HZ from the Main

Menu.

2. Enter a point name for the first point in the job that will not

conflict with the names that are in the control file. In this
example, you could enter either any alphanumeric name or any
numeric name that is above 10. (Accept the default coordinates
for now – they will be overwritten later.)

3. Select

the

Files

tab from the Settings screen.

4. Tap

the

%URZVH button in the

Control File

section of the screen

and select the job that you want to use as a control file.

5. Define

your

Occupy

and

Backsight

points using points from the

control file and enter the point name that was just created as the

Foresight

.

6. Take a side shot or traverse shot and overwrite the original

coordinates with the new coordinates. This will tie in the
coordinates for the new point with the coordinates in the control
file.

7. Continue your survey.
