Yet another AGU 2012 session on lidar, high-resolution topography, and change detection that could be of interest to the OpenTopography community: EP023: Quantifying Hillslope and Fluvial Processes Through Change Detection Using High-Resolution, Multi-Temporal Topographic Data Increasingly geomorphologists are using repeat topographic datasets to quantify rates of geomorphic processes. Repeat topographic surveys from aerial, ground, and boat-based platforms are making possible high-resolution change detection over large spatial extents thanks to technologies like LiDAR, Structure-from-... more

Representatives from NCALM, UNAVCO and OpenTopography are organizing the following session at the 2012 American Geophysical Union (AGU) in San Francisco, December 3-7, 2012. The abstract deadline is August 8th. G015: LiDAR Topography and Geodetic Imaging: Emerging Techniques and Applications Description: Session will focus on geodetic imaging (GI) technologies, including InSAR, and LiDAR collected from aircraft, helicopters, UAVs, and terrestrial systems. Of particular interest will be presentations concerning the latest developments in instrumentation, processing of observations, and... more

It is 2012 American Geophysical Union (AGU) session announcement season. This is a session convened by several OpenTopography collaborators that will be of great interest to the OpenTopography community: We invite you to join us at the 2012 AGU Fall Meeting for a session titled "4-D Lidar: changes to Earth's surface measured from differencing repeat dense topographic datasets." The recent explosion in sub-meter resolution topography mapped in particular by airborne and terrestrial Lidar raises the possibility of mapping changes to Earth's surface in unprecedented detail, with the potential... more

A pair of recent publications related to paleoseismic research in California feature lidar topography data accessed and processed via OpenTopography. Both papers utilize B4 lidar data extensively, and OpenTopography played an integral role in providing access to both the point cloud and custom digital elevation models discussed in the publications. The first publication - LaDiCaoz and LiDARimager--MATLAB GUIs for LiDAR data handling and lateral displacement measurement, Zielke and Arrowsmith, Geosphere, February 2012, v. 8, p. 206-221 - presents MATLAB-based software for calculating "... more

At last month's UNAVCO Science Workshop they introduced an evening of Ignite talks presented by members of the UNAVCO community. The event was well attended and quite fun. The full set of videos are now available here: http://igniteshow.com/events/2012-unavco-science-workshop Of particular interest to the lidar community is Ben Brook's (UH Manoa) talk, "The Balloon and Lidar" about his work with Craig Glennie (University of Houston) to build a balloon (or backpack) based lidar system. The system has the potential to bridge the gap between terrestrial and airborne lidar, providing detailed... more

Back in December, ASU graduate student Gayatri Marliyani and OpenTopography co-PI Ramon Arrowsmith traveled to Indonesia for research. During the trip they made a visit to Universitas Gadjah Mada (UGM), Yogyakarta, the oldest and largest university in Indonesia. While at UGM, Gayatri and Ramon led a one day lidar short course to promote the utilization of lidar technology for research in Indonesia. They used training materials from previous OpenTopography short courses to provide an introduction to lidar and the OpenTopography project for the students and academic staff at UGM. Their... more

Barrett Salisbury, a graduate student at ASU and regular OpenTopography user, is conducting a research study - Remotely measuring tectonically offset geomorphic features using light detection and ranging (LiDAR) data - to explore the "repeatability, accuracy, and precision" of lateral fault offset measurements made on lidar topography data. Barrett is asking for participants with a geologic background to take part in his study: Greetings! I am a graduate student under the direction of Dr. Ramon Arrowsmith in the School of Earth and Space Exploration at Arizona State University. For the... more

Nancy Glenn at the Boise Center Aerospace Lab (BCAL) wrote to encourage us to spread the word about a post-doc position she is currently advertising in remote sensing & visualization. Nancy is a member of the OpenTopography advisory committee and has led the development of the BCAL LiDAR Tools for ENVI. She is also a leader in the Idaho Lidar Consortium and involved in a range of interesting research related to lidar and remote sensing. A copy of the post-doc announcement is below. The web announcement can be found here: http://bcal.geology.isu.edu/975.shtml Department of Geosciences;... more

Fabio Pacifici, the Chair of the Data Fusion Technical Committee of the IEEE Geoscience and Remote Sensing Society (GRSS) emailed the following announcement to encourage the OpenTopography community to participate in the 2012 IEEE Geoscience and Remote Sensing Society (GRSS) Data Fusion Contest. More information: 2012 IEEE GRSS Data Fusion Contest: This year the Contest is designed to investigate the potential of multi-modal/multi-temporal fusion of very high spatial resolution imagery. Three data sets of three different types (optical, SAR, and LIDAR) over downtown San Francisco are made... more
