Gigapan: Robert Mark


Gigapans allow us to view an entire rock art panel or larger landscape with multiple panels. They also allow us to zoom in to view specific details of the panels. This is particularly useful for the study of techniques of manufacture, superposition, and condition. In addition to general documentation, we have used gigapans to assist in identifying sample locations for portable X-ray fluorescence (pXRF) measure of pigment composition, and in the selection of sampling sites for Carbon-14 dating. During 2011, we developed a method to use flash photography to acquire gigapans of rock art in the dark zone of caves (research paper can be found here). Links to other examples can be found here.

Guest Editors

Robert Mark, Ph.D. and Evelyn Billo

Robert Mark (Chief Scientist) and Evelyn Billo (CEO) founded Rupestrian CyberServices in 1997 to pursue rock art research, documentation, and education.

While working on a US Geological Survey project around 1980, Evelyn and Robert were asked by the park superintendent to evaluate the geology of the newly discovered solar marker on Fajada Butte. Thus began their enduring interest in rock art studies.
