Reference Line (RL)
The RL project associates and orientates GPR profiles to a straight-line reference. This can be any type
of physical line that can be referred to during and after data collection. Examples include boundary,
curb or fence lines, or simply a metering-tape laid on the ground. Regardless, one end of the line needs
to be defined as the starting point and then equidistant points marked along its length. Profiles are
then gathered in straight lines, perpendicular to the reference line, and a reference-marker is placed
within the GPR data every time the reference line is crossed, as illustrated in Figure 17, below.

From the project start screen (

below), you will be prompted to enter a project name and the
distance between each profile. Once entered, press the ‘Start the Project’ button to continue.
