SliceView

8 SliceView
A key feature of Conquest is its ability to transform the raw sensor information into a series of
depth-based slice images cutting down through the concrete (Figure 8-1). In general, depth slice
images are generated after all the lines in the grid have been collected, but images can also be
generated when a partial grid (minimum 3 lines) has been collected. This is useful when the grid
area is smaller than the grid mat or when part of the grid is obstructed and not all the lines can
be collected.
The best way to think of the depth slices are as photograph-like views from above slicing 1 inch
(25 mm) at a time into the subsurface.
Figure 8-1: A conceptual Conquest Grid Scan image to understand the relationship between depth slice images,
Alpha GPR Lines and Numeric GPR Lines. The rectangular regions to the bottom and the right should be thought of
as GPR Lines through the concrete in each direction at the positions of the crosshairs.
After a Grid Scan is complete and SliceView selected, the data are processed and depth slices
are generated and displayed.
The PCD data are also processed to generate a PCD slice image that is displayed in the
SliceView menu.
It is not necessary to reprocess data every time you want to view it. Once a grid has been
processed, the images are always immediately available by selecting SliceView from the Grid
Scan menu.
