(chuckle) No. I can't imagine how you could get a scanner plus power close to some of these sites. Many of them are up in the interior of piles of rock a hundred or more feet above the plain, and most are miles and miles away from the nearest power plug. And some of them are in really odd positions (down near the base of the rocks)
“Laser scanning was found to be a good technique for the 3D noncontact
recording of rock art. The equipment is suitable for
use in the field – even in remote locations.”
CASE STUDY 3
As part of the English Heritage Rock Art Pilot Project
(1999), laser scanning as a method of documenting rock art
in the field, was examined. The petroglyphs studied are
located on Rombald’s Moor in West Yorkshire. The areas
scanned were approximately 1.2m ? 0.5m in size. Laser
scanning was found to be a good technique for the 3D noncontact
recording of rock art. The equipment is suitable for
use in the field – even in remote locations.
The petroglyphs on Rombald’s Moor,West Yorkshire.
The data obtained documented the petroglyphs to a high
level of detail. Importantly, the results were not subjective to
lighting conditions at the time of data capture. Indeed, once
the data had been post-processed, and was examined under
varying lighting conditions, a distinct wear pattern was
located on the surface of one of the rocks. This pattern had
not been discernable from photography, nor with the naked
eye. The results of laser scanning can be exploited in a wide
variety of imaging formats, providing a flexible digital
archive. Images of contour maps of the surfaces and a scale
replica in polyurethane were also produced from the data.
“Accessibility is also important, and the equipment required can easily be carried
by one or two people over considerable distances.”
CASE STUDY 8
Recording prehistoric rock art by photogrammetry and laser scanning
Why was scanning was selected?
The photogrammetric technique developed for this project is
user friendly, cost effective and time efficient. For a
monument type such as this, where the carved stones are
relatively small, prolifically scattered and often physical
isolated, these are crucial issues. Accessibility is also
important, and the equipment required can easily be carried
by one or two people over considerable distances. These
attributes make the technique highly suited to the volunteerled
baseline recording part of the project. In contrast, laser
scanning is relatively expensive and requires specialist
equipment and expertise..
