Overview:

Lidar data has become an important tool for earthquake scientists to make detailed observations and model surface evolution. Within the last 7 years, several efforts have been made to collect high resolution topographic data for active faults (e.g. The B4 project, EarthScope and NCALM projects). These datasets are available freely online through OpenTopography, a NSF funded lidar data distribution portal. The active tectonics community has taken great interest in these exciting datasets, using them to generate new and important insights into earthquake processes in Southern California.

OpenTopography in partnership with SCEC, UNAVCO, and EarthScope will host a short course at the San Diego Supercomputer Center at UCSD, November 4-6, 2013. This 3-day course will highlight recent research results and provide beginner to intermediate training on airborne and terrestrial lidar technology, point cloud and raster-based data processing, and active fault-oriented analysis. We will emphasize fault trace and geomorphic mapping applications, topographic differencing, integration with other geospatial data, and data visualization and analysis approaches.
