6.8.3 Color

Pressing this button changes the color palette for the GPR Lines. There are 9 different color
palette options.

6.8.4 Filter

When the filter is on, flat-lying responses in the data (like the surface response described in
Section 2.2) are filtered out so that shallow hyperbolic responses from objects like rebar and
conduits are enhanced. It will also filter out other flat-lying responses, such as bottom of
concrete, so be careful when using this option (Figure 6-12). The filter is set to OFF by default.

6.8.5 Gain

Gain is used to amplify the response to enhance weak features in the data image. Gain values
vary from 1 to 8 with 1 meaning a minimal amplification has been applied and 8 meaning that
maximum amplification has been applied. Pressing this button increments the gain; once you
reach 8 it cycles back to 1. Avoid over-gaining the data as it can make interpretation difficult
(Figure 6-13).
