7.1.5 Color
Pressing Color changes the color palette for the GPR Line. There are 9 different color palette
options. The image is automatically re-displayed as the color palette changes. A few sample
color palettes are shown in Figure 7-13.
7.1.6 Filter
The Filter is a background subtraction filter used for removing flat-lying responses in the data.
Filtering helps identify shallow targets that might be masked by the strong signals at the top of
the image, as well as possibly enhancing the visibility of hyperbolas further down in the data.
