Tracing is another way to document rock carvings. The surface is covered with plastic, and details as carvings, depressions and cracks are sketched on the plast, with a pen. In this documentation the size of the plast sheet was 1,80 m. X 90 cm. The size fits with the scanner. The thickness of the plast was 0,1 cm. It is important to use a pen with waterproof colour.
The following pictures are thanks to Sven Gunnar Broström and Kenneth Ihrestam, when we met them at work 😉 They have a lot of experience in documentation, and has documented many carvings at the eastcoast of Sweden.
In my opinion, I think the tracing method is inspired by archaeological drawing. -The object is placed under a see-through box, a thin see-through paper is placed upon the box. With very thin pencils, the details are drawed with a dotting technique. For more info, please have a look in the menu “documentation -archaeological drawing” (coming soon, page under construction). I think tracing is a useful method to map the carvings, so their position on the panel is copied 1:1.
