7.3 Data Collection
7.3.1 Physical Data collection
It is critical that the starting position is consistent on every line. Line up the middle of the unit
with the starting line, and then push the system straight towards the end of the line. It is helpful
to have a marker at the end so you have something to aim for.
7.3.2 Data collection on the Display Unit
The data collection screen is shown in Figure 7-8. The right half of the screen is a graphic
representation of the grid, illustrating the size of the grid and the lines that need to be collected.
The left half of the screen will display the last grid line collected.

Press Start when you are positioned at the start of the line. Push the system in a straight line
towards the end of the line. The system knows the length of each line, and will automatically
stop acquisition once that distance has been covered. If the data acquisition ends prior to
reaching the end of the line, or continues noticeably past it, you likely need to do an Odometer
Calibration (
Section 4.2.6).
Once data is collected, the Grid Line will turn red and the system will beep twice. The current
line will now advance to the next one and is shown in white. The remaining lines to be collected
are shown in green (Figure 7-9).
