The annual American Geophysical Union (AGU) Meeting will kickoff on Monday in San Francisco. OpenTopography will be on display at the GEON booth in the Exhibit Hall (#315 in the Exhibit Hall, Moscone South). OpenTopography team members will be on-hand to discuss and demonstrate the latest updates to the site and to show off newly released data. Please stop by the booth and say hi.
OpenTopography-related scientific presentations:

We have updated the OpenTopography Short Courses page with the lectures, tutorials and sample data, and related documents from last weeks Southern California Earthquake Center sponsored Short Course: Using EarthScope and B4 LiDAR data to analyze Southern California’s active faults. This course was focused on applications of lidar to active faults, but the course materials include lectures on lidar technology, data processing, data sources, and examples of other scientific applications. Tutorials include exercises on visualization and analysis of lidar point clouds and digital elevation... more

Lectures, tutorials and sample data, and related documents from the 2009 Geological Society of America Short Course, Introduction to the acquisition, visualization, and interpretation of airborne lidar-derived digital elevation models, are now available via OpenTopography. The course materials include lectures on lidar technology, data processing, and considerations for designing data collections. Tutorials include exercises on visualization and analysis of lidar point clouds and digital elevation models. These materials are an excellent resource for anyone seeking to get up to speed on... more

This week OpenTopography rolled out increased LiDAR point could processing limits and a simplified scheme of user access levels. OpenTopography is a authenticated system whereby users have certain privileges for data access, processing limits, and system features. User level is defined for each user and applied when the user is logged into OpenTopography. The new scheme simplifies users into three levels:
Guest Users: Access to 50 million points per job. No access to the customized myLiDARjobs which allows you to view all previously submitted jobs, monitor jobs that are currently... more

A joint SCEC/OpenTopography/USGS/UNAVCO research and education workshop
December 3 and 4, 2009 @ San Diego Supercomputer Center
Workshop organizers:
J Ramon Arrowsmith, Arizona State University
Christopher Crosby, San Diego Supercomputer Center / OpenTopography
Ken Hudnut, US Geological Survey
Susan Eriksson, UNAVCO
Workshop overview:
As a result of research in the Eastern California Shear Zone, the B4 project, and the recently completed GeoEarthScope data acquisition, most of Southern California's active faults have now been scanned using LiDAR. These exciting new data powerfully depict the... more

Available GeoEarthScope LiDAR data in southern California has now grown to include the Elsinore fault, the Burro Flats segment of San Andreas fault, and the Crater Mountain portion of the Owens Valley. These data are a new addition to the GeoES SoCal coverage that includes the previously released Garlock fault data. The newly released data are available via OpenTopography in both Google Earth viewable hillshades images and in standard digital elevation model format. Point cloud data for these new fault segments will be released shortly.

OpenTopography is pleased to announce that the Nephi North portion of the Wasatch fault LiDAR data set, acquired during the GeoEarthScope Intermountain Seismic Belt (ISB) project is now available. The majority of the ISB data set was released via OpenTopography in May, but due to additional data processing challenges, the Nephi North segment of the data set was not distributed at that time.
Like the rest of the GeoEarthScope LiDAR available via OpenTopography, data are available as point clouds and custom digital elevation models, standard digital elevation models, and as hillshade images... more

We are pleased to announce the availability of LiDAR point cloud data from the Garlock fault portion of the GeoEarthScope Southern & Eastern California project. With this release, Garlock data can now be downloaded via OpenTopography as point clouds and custom digital elevation models (DEMs), Google Earth hillshade overlays, and as standard tiled DEMs.

As of today, it is now possible to download standard LiDAR DEM tiles in bulk via the OpenTopography Portal. We have released a new bulk downloads of LiDAR DEM tiles page that makes this capability possible. This new feature of the OpenTopography Portal is a direct response to frequent requests from users for a less labor intensive method to download DEM tiles. Until today, users wishing to access a large number of DEM tiles were required to manually click and download each tile via our Google Maps-based Standard DEMs interface.
This feature of the OpenTopography Portal essentially... more
