As a part of TubeX project, we also seek to develop a library of different lava tube geometries and their corresponding GPR image from their migrated sections. The GPR image library will encompass a range lava tube geometries, including tubes of different heights, widths, shapes, and structures (e.g., pillars), plus a variety of floor textures (e.g., smooth, ropey, rubble) and overhead thickness. This library will be an asset for determining the utility of deploying GPR technology in mapping a tube-rich environment.
TubeX data collection at LBNM took place in two phases in April-May 2017 and September 2018. In total, the two campaigns acquired ~8.4 km of GPR data over Valentine, Skull, Hercules Leg, Indian Well, Natural Bridge, Incline, and Ship & Dinghy caves.
You can find GPR data and images library in the following links for different caves categories:
