A Joint OpenTopography, UNAVCO, NCALM and EarthScope short course
UNAVCO facility in Boulder, Colorado
April 18-19, 2016

High resolution topographic data has become an important tool for earthquake scientists to make detailed observations and model surface evolution. Within the last decade, several efforts have been made to collect high resolution topographic (HRT) data for active faults (e.g. The B4 project, EarthScope, and numerous NCALM and USGS projects). These datasets are freely available online through OpenTopography, an NSF funded data distribution portal. The active faulting community has taken great interest in these exciting datasets, using them to generate new and important insights into earthquake processes. OpenTopography in partnership with UNAVCO, NCALM, and EarthScope will host a short course in Boulder, Colorado on April 18-19, 2016. This 2-day course will highlight recent research results and provide beginner to intermediate training on airborne and terrestrial lidar, and Structure from Motion technology, point cloud and raster-based data processing, and active fault-oriented analysis. We will emphasize fault trace and geomorphic mapping, topographic differencing, integration with other geospatial data, and data visualization and analysis approaches. Participants will have opportunities to discuss their research with other participants and the instructors.
Driving directions to UNAVCO from Denver international Airport
Send your flight details to firstname.lastname@example.org and she will coordinate rental vehicles.
Monday, April 18: 8am-5pm, followed by an evening program, 7:30-9:30 pm
Tuesday, April 19: 8am-5pm
Additional Information Shared student lodging, breaks, and lunch will be covered for all participants. In addition, up to $200 for other travel expenses may be available with emphasis on students and early career scientists. We will be handing out and explaining the travel reimbursement process during the course.
If you plan to bring your own computer, the software that should be installed and functioning prior to arrival includes:
We have put together a reading list that contains a number of relevant papers that you may find helpful to review prior to the course (highest priority is shown in italics).
On Monday evening, we will have short presentations by participants. You are STRONGLY encouraged to make one of these short (<5 minutes/<5 slides) presentations. We will have a computer and projector there and will collect the presentations in advance for quick transitions. Given the big group, we will be strict on timing, but we do look forward to hearing about your work, your ideas, or even questions. This will be very informal!

Exploratory Small Projects:
Individually or in groups, identify a small area of interest to perform a simple change detection or other geomorphic analysis. Use what you learned in yesterday afternoon and this morning's exercises, starting with an LAS file to explore and analyze the dataset of your choosing. A few example datasets for change detection are below, or use OpenTopography to find a dataset of interest and to download a point cloud file. By 4pm, make 3 (max) slides, that summarize: 1) Problem/question, 2) workflow/analysis, 3) result.
