GEORADAR-EXPERT
supports work with two-dimensional and three-dimensional representation of GPR
profiling data and their processing results. When a file is opened, a workspace
adapted to the specifics of the loaded data type is generated automatically.
The
workspace of the software suite is organized as tab groups. Each group combines
control panels by functional purpose. Fast switching between tabs allows the
user to focus on the current task by displaying only the relevant controls for
data processing and visualization.
Examples of
the main window of the software suite in different workspace configurations are
shown below.
GPR
profile visualization tab. Panels for controlling profile visualization, its
parameters, and processing are located in the bottom tab group.
Attribute section creation setup tab and subsurface
environment neuromodel visualization tab. Histograms for visualization of the
automated BSEF analysis result are located on the left side of the workspace.
Attribute section tab with terrain correction.
Tab for visualization of the statistical analysis
result of GPR data. The interactive plot provides a threshold for detecting
violations according to the specified rule. Threshold violation areas are shown
in red. Positions of violation areas and their characteristics are exported to
an MS EXCEL spreadsheet.
Tab for visualization of a 3D assembly of sections
with the upper quarter of the volume cut out. Visualization axes are rotated
using the mouse. Viewing angles of the 3D assembly and the light source
position can be specified numerically using the corresponding parameters.
Tab for visualization of the volume of a 3D assembly
of sections with orthogonal slices. The position of each slice can be adjusted
interactively using the mouse or by precise numeric specification of
coordinates. Creation of a curvilinear vertical slice by the user is also
provided.
Tab of a horizontal slice of the volume of a 3D
assembly of sections. Similar
separate tabs are provided for vertical slices.
The volume
of a 3D assembly of sections can be divided for visualization using isosurfaces
created by specified attribute values. This makes it possible to highlight
layer boundaries or contours of anomalous zones. After isosurfaces are created,
export of a table with calculated volumes of the selected areas in MS EXCEL
format becomes available.
The
tab below shows a visualization where isosurfaces are shown in purple and the
volume of the 3D assembly is made semi-transparent for clarity.
Below, a visualization option for the 3D assembly volume is shown, where full transparency is assigned to the attribute value range specified by the user, and an isosurface is used as the boundary between the transparent and opaque regions of the 3D assembly volume.
Next, a visualization option for the 3D assembly volume is shown with the display of GPR profile positions enabled as white lines, and with slices along these profiles. The 3D array contains one semi-transparent red isosurface that shows the position of the top of the lower layer. Different transparency levels are set for the isosurface and for the 3D assembly array.
