GPR Visualisation Options

The View pull down menu offers multiple options on how each GPR profile is displayed on the screen in Geolitix.

All settings in View are part of your user preferences and will remain the same for your next projects, until you alter them.

Changing the GPR profile colours
Geolitix allows the user to select from various colour schemes for their GPR data. Although a standard greyscale will be shown in all examples, you may select from 12 colour schemes. Each of these can be mirrored or reversed using the and icons.

Vertical axis
The Vertical axis pull down allows the user to display data with a two-way travel time, depth or elevation as the y-axis. To display data in depth, a project velocity must be set.

Horizontal axis
By default the x-axis on the profiles shows the trace number. Enabling this option will switch the axis to linear distance. Note that if the positioning was done based on GPS, in order to see the linear distance mode, a Resample Traces Equidistantly processed must be applied first.

Zooming and scrolling GPR profiles
The default viewing mode is to allow the data to be zoomed horizontally using the mouse scroll wheel. However, you can set the trace width to be locked at a selectable number of pixels. In this mode (Fixed trace width), the mouse scroll wheel pans the radar profile left and right on the screen.

Show unprocessed
If this option is on, the profile view will be split to show the data before (above) and after (below) processing, when a processing step is selected.

Show markers
Some GPR manufacturers allow markers to be inserted into their GPR data. With this options they will be shown as a vertical red line.
