GPR-SLICE tutorial video: how to process Proceq concrete GPR data in GPR-SLICE

In this video, I explain how to process GPR data collected on a 60cm x 60cm area on a concrete slab using the Proceq GPR Live equipment.

Processing the data can be done in under a minute, if you have set GPR-SLICE up correctly.

To purchase GPR-SLICE software, please see here.

A full list of all GPR-SLICE training videos is available here. You will probably be interested in GPR-SLICE’s BridgeDeck automatic hyperbola detection system (useful for creating rebar deterioration maps), and the automatic layer detection system (for mapping concrete slab thicknesses, for example).
