Figure: 12-15 For collecting GPR data consisting of long data lines it makes more sense to follow a
forward and reverse surveying pattern. For the final data to be spatially correct with a minimum of
editing, data collected in this pattern should be on lines that extend completely from one baseline to the
other.
XY Lines – Forward and Reverse
Using the Forward and Reverse survey format, XY line data are collected in the pattern shown in
Figure 12-16.
When data are collected like this, it is important that lines start and end on established baselines,
otherwise, when lines are reversed to the correct orientation for the display, they may be offset
from one another.
