Jamie Quartermaine from Oxford Archaeology was determined to find out.
Jamie contacted Opti-cal Survey Equipment and explained the project and its difficulties. After speaking to our Laser Scanning team, who have extensive experience with both terrestrial scanners and the GeoSLAM instruments, he was advised to Hire a GeoSLAM ZEB-REVO, which would be perfect for the task in-hand.
The ZEB-REVO, capable of collecting data swiftly in 3D without the need for multiple set-ups, would allow Jamie to collect the data easily and quickly.
Jamie’s first stop was the Schneller building in Jerusalem. In its 160 year history it has been used as an orphanage, barracks and ammunition arsenal. Just last year, an archaeological team unearthed the remains of a Roman bath house and winery underneath the site. The next stage of the buildings history is a conversion into a museum of Judaism – hence the requirement for a complete, high-accurate survey of the site.
Made up of 4 floors, 130 rooms, an outer courtyard and a number of stables, Jamie needed to work quickly to scan the entire site. Using the ZEB-REVO, in 3x 30 minute scans he captured the entire building, including survey control points to georeference the data. Using traditional scanners, this would have taken several weeks and involved multiple set-ups.
For the second scan, a 12th Century Benedictine monastery. With no more than 30 minutes between the end of the Vespers – the evening service – and the time the public were allowed back in, Jamie carried out a quick reconnaissance and accurately captured the unique domed building.
The final port of call was a decapitated 19th Century merchant house in the ancient Arab town of Jaffa. The challenge here was to record the building while the construction works were in progress, with hoardings and scaffolding obscuring structures. A near impossible task but the ZEB-REVO was still able to collect survey-grade data in a matter of hours, which formed the basis of a working record of elevations, sections and plans.
In under 48 hours Jamie had captured highly accurate 3D datasets of 3 heritage buildings. Proof that with the GeoSLAM handheld scanners what use to take weeks can now be done in hours.
