From the Jerusalem Post:

Using an innovative three dimensional technology, researchers have now made the Timna Valley Park the first setting in Israel where a large-scale rock engraving was scanned.
The project was headed by a team from the Computerized Archaeology Laboratory in the Institute of Archaeology at the Hebrew University of Jerusalem. The laboratory combines advanced mathematics and computing methods with modern, high-precision scanners to provide digital three dimensional models of archaeological finds. Dr. Leore Grosman directed the project by in collaboration with Assaf Holzer and the Timna Valley Park team, who provided important help and support.
The researchers’ first goal in scanning the engraving was to create a durable, long-lasting and accurate 3D model in case of future damage to the original. Their other goal was to create a precise model that will allow an objective study of the engraving, in order to gain a better understanding of the people who made it.
