Rib Vault GPR Survey from Above — Backfill Thickness and Structural Geometry
Description
GPR profiles acquired from above a rib vault in a cathedral, with a GSSI UtilityScan DF dual-frequency antenna. Three profiles crossing the vault, recorded from the extrados side to measure the thickness of the backfill covering it. Raw unprocessed files.
The vault reads as a curved reflection whose depth varies continuously along the profile: shallow at the crown, deeper towards the springing. The points where that curve begins and ends mark the extent of the vault — the information a structural survey needs before locating loads, planning an intervention or assessing the fill above.
