Information and discussion related to high-resolution lidar topography for the Earth sciences

New Point Cloud Processing and Custom DEM Video Tutorial

Thanks to the ASU Capstone team - a group of senior undergraduate School of Computing and Informatics students at Arizona State supervised by OpenTopography Co-I Ramon Arrowsmith - we now have a very nice video tutorial on how to use OpenTopography to download and process LiDAR point cloud data to digital elevation models:

Southwest Idaho Regional LiDAR Conference

OpenTopography received the following information about this upcoming event in Boise via email today. The conference theme is "Light Detection and Ranging laser technology (LiDAR) to plan for, mitigate and solve public safety issues" and the list of topics looks interesting. Details in the announcement below:

Golden Gate LiDAR Project

Another new LiDAR data collection funded with stimulus dollars that I recently became aware of is the ARRA Golden Gate LiDAR Project. Led by San Francisco State University and funded by USGS ARRA, this project will collect data in coastal regions around San Francisco:

LiDAR 101 Video

I just stumbled upon this LiDAR 101 video, produced by the Carl Vinson Institute of Government at University of Georgia, while Googling for something else. In ~13 minutes, it does a nice job of summarizing LiDAR technology, data products, the costs associated with acquiring data, and various applications. It is worth a watch if you are looking for a quick crash-course in LiDAR or need a video to show in the classroom:

Workshop Announcement: New Tools in Process-Based Analysis of Lidar Topographic Data

Please see the following announcement for an upcoming NSF-sponsored workshop on “New Tools in Process-Based Analysis of Lidar Topographic Data,” to be held June 1-2 at the University Corporation for Atmospheric Research (UCAR) in Boulder, Colorado. The goal of the workshop is to "provide researchers in Earth surface processes with an opportunity to gain hands-on knowledge in new methods for analyzing high-resolution topographic data. Participants should have active research projects using lidar data (airborne or ground-based).
