X Lines Only
Set up a first-quadrant XY grid. Data lines run in the X direction, distance increasing from the Y
axis baseline. Line numbers increase in the positive Y direction (see
Figure 13-10 ). Lines must
be equally spaced. It is not critical that all the lines are the same length. However, it does make
processing easier if all the lines start at the same baseline position (usually defined as zero
(0.0)).
Figure: 13-10 Proper X Line surveying pattern. Following this pattern and starting each line from the same baseline
minimizes the data editing required to produce a spatially accurate map of GPR data.
