Let Sleeping Bats Lie
HOW DO YOU PRODUCE AN ACCURATE POINT CLOUD OF A 170M TUNNEL, WITH NO HUMAN ACCESS PERMITTED, THAT’S ALSO HOME TO ONE OF BRITAIN’S RAREST BATS HIBERNATING OVER WINTER?
Located in a steep valley in the Pembrokeshire countryside between the coast at St Brides Bay on one side and the River Solva on the other, the Solva Water Treatment Works has no access routes apart from an unused 170m tramway tunnel linking it to the town’s harbour. The only alternative is a demanding twenty minute uphill walk that makes the transportation of equipment to the works particularly arduous.
