Napa Watershed Data Release:
OpenTopography is happy to announce that point cloud LiDAR data for the Napa Watershed in northern California is now available. The Napa data were collected in 2003 by the National Center for Airborne Laser Mapping (NCALM). This was one of the original NCALM data sets and digital elevation models derived from these data have been available via the NCALM Data Distribution Center for quite some time. However, this release of the data by OpenTopography marks the first time that the full Napa point cloud data set has been available for download. The Napa data set... more

OpenTopography is pleased to announce the release of our updated LiDAR point cloud access and processing system: OpenTopography 2.0 (OT 2.0). This release has been available in beta for the past couple of weeks, but we've now fully migrated the functionality to the production OpenTopography point cloud system.
The OpenTopography 2.0 release represents significant modifications to the OpenTopography point cloud system in an effort to enhance functionality, stability, scalability, and performance. Although modifications to the system from the user's perspective are not dramatic (moderate... more

We are pleased to announce the 7th Cyberinfrastructure Summer Institute for Geoscientists (CSIG) to be held August 9-13 at the San Diego Supercomputer Center on the University of California, San Diego campus.
General and program information, as well as online registration is available at http://www.geongrid.org/csig10.
The broad theme for CSIG'10 will be emergent Geoinformatics approaches to 3D and 4D integration of geoscience data. Given the diverse interests of past CSIG participants, and based on feedback that they have provided, CSIG'10 will feature two "tracks" of instruction:

Last week, as part of the Fifteenth Annual Science-Engineering-Technology Congressional Visits Day (SET CVD) program, OpenTopography presented a demonstration of LiDAR data on Capitol Hill in Washington DC. OpenTopography was invited, along with David Phillips from UNAVCO, to participate in the event by the American Geological Institute (AGI). The LiDAR demo was part of the SET CVD LaserFest reception, in celebration of the 50th anniversary of the laser, held in the foyer of the Rayburn House Office Building.
OpenTopography team member Chris Crosby shows LaserFest reception attendee a... more

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.
The Zielke, et al. study used 0.25 and 0.5 m DEMs generated... more
