Fall AGU Special Session on Ground Based Geodetic Techniques and Science Applications

Posted on Tue, August 10, 2010 by Chris Crosby in MeetingsTLS

Session announcements for the fall American Geophysical Union (AGU) meeting in San Francisco are beginning to appear.  The following session on ground based geodetic techniques includes an emphasis on terrestrial laser scanning:

Dear Colleagues:

We would like to bring to your attention the following special session on Ground Based Geodetic Techniques and Science Applications to be held at the 2010 Fall AGU Meeting in San Francisco, December 13 - 17:

Ground Based Geodetic Techniques and Science Applications
Ground-based geodesy is a rapidly expanding and evolving technology. Tools such as terrestrial laser scanners (TLS) and/or ground-based radars (GBR) promise to expand our detailed understanding of the fundamental processes that drive a broad range of spatial (3D) and temporal (4D) science applications. We invite contributions that discuss both the technical aspects of the technology and process-based geoscience studies using ground-based geodetic tools such as, but not limited to, TLS and GBR. What are the strengths, weaknesses, and limitations of the technologies? How is the technology being used to address static and dynamic scientific problems? We encourage contributions from a wide range of disciplines.

Best regards,

Benjamin Brooks, David Phillips, and Gerald Bawden - Session conveners

Geoscience Applications of High-Resolution Digital Topography in Arizona

Posted on Sun, August 01, 2010 by Chris Crosby in NewsPublicationsResearchTLS

The latest edition of the Arizona Geological Survey’s online Arizona Geology magazine has a nice article on recent applications of airborne and terrestrial LiDAR to geoscience research in Arizona written by David Haddad, a graduate student in ASU’s Active Tectonics, Quantitative Structural Geology and Geomorphology research group.  For his MS research, David used LiDAR data from both airborne and terrestrial platforms to characterize the geomorphic settings of precariously balanced rocks in the Granite Dells near Prescott, AZ.  Precariously balanced rocks (PBRs) can be used as negative indicators of strong ground motion caused by earthquakes, and their spatial distribution provides an indication of the intensity of ground shaking in a given location.  For more on PBRs, see David’s other Arizona Geology article: Nature’s Balanced Seismometers.

David’s article provides a nice overview of LiDAR technology, a few nice graphics like the one above, and a good intro to how these data have been applied to his PBR research in Arizona.
