WebA collection of 2-D GPR scan lines from grids with parallel and perpendicular lines create 3-D images of the interior of a concrete slab. Each scan line produces a single cross-section. The plan view color maps are created by gathering adjacent cross-sections and processing these ground penetrating radar ( GPR ) results in to a plan view diagram.
