Webinar: EKKO_Project (V4) SliceView module for depth slicing GPR grid data

Collecting GPR data in a grid and generating 2D depth slices is a powerful way to reveal targets and understand the spatial relationships between subsurface reflectors; applicable for many GPR applications including utility–locating, archaeology, forensics, and concrete scanning. The SliceView module in the EKKO_Project™ software is used to process GPR grid data and output depth slices.
