March 07 2010 : OpenTopography enables detailed analysis of San Andreas Fault--new results published in SCIENCE

    Recent ASU Ph.D. and current Post-doc Olaf Zielke and OpenTopography Co-I Ramon Arrowsmith and colleagues published the results of their study of offset channels along the southern San Andreas Fault in Science last week. They had two reports in the issue which were also highlighted in a perspective by Kate Scharer of Appalachian State University.  The cover image of Science featured a 0.25 m digital elevation model (DEM) and hillshade of offset channels along the San Andreas Fault in the Carrizo Plain produced by OpenTopography.
