Archaeology Channel video This from Pettigrew:

Digital laser imaging technology is not only
very cool, but it is also much faster and more accurate than hand
drawing for architectural features found at archaeological sites.
This fact is made obvious in Mesa Verde: A CyArk Case Study, the
latest video feature on our nonprofit streaming-media Web site, The
Archaeology Channel (http://www.archaeologychannel.org).

The complex World Heritage site of Mesa Verde is a good challenge for
CyArk, a Kacyra Family Foundation project that is preserving the
world's most valued cultural heritage sites in three-dimensional
digital form. Ancestral Puebloans at Mesa Verde built cliff
dwellings in AD 1200-1300. A field team in 2005 visited one site
there, Spruce Tree House, to test CyArk's advanced documentation
techniques. This video shows how CyArk is preserving the site in
digital imagery through laser scanning and the most accurate 3D
models possible today.
