Figure 7-6: Marking ending positions
For linear targets such as pipes and utilities, the best GPR responses occur when the GPR
survey line crosses the target at right angles. Keep this in mind when laying out the grid and the
orientation. Sometimes, laying out a grid with straight lines and corners at 90 degree angles
can be difficult.
An example grid layout is shown in Figure 7-7.
