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.

By downloading this file and opening it in Google Earth, users are able to browse hillshades with two illumination angles (315 and 45 degrees) for faults in the northern San Andreas fault system. The Google Earth file remotely accesses data stored on GEON servers to allow users to seamlessly browse the full NoCal dataset from within Google Earth.
The entire San Andreas fault system has now been imaged utilizing GeoEarthScope Northern California Airborne LiDAR Data , along with many other important geologic features, and is available for download via the GEON Portal. This entire dataset is now available as 1 km^2 tiles of 0.5 m digital elevation models - both unfiltered (all data)and filtered (bare earth) in ESRI (ArcGIS) binary grid format. Complete metadata are also available for download.
