Sharon Bywater-Reyes, University of Northern Colorado
This exercise will walk you through 1) basic operations and use in CloudCompare, and 2) use of an Open-Source plugin in CloudCompare called CANUPO (http://nicolas.brodu.net/en/recherche/canupo/) that allows for ...

Topographic differencing: Earthquake along the Wasatch fault part of Teaching Activities
Chelsea Scott, Arizona State University at the Tempe Campus
After a big earthquake happens people ask, 'Where did the earthquake occur? How big was it? What type of fault was activated?' We designed an undergraduate laboratory exercise in which students learn how ...

Unit 2.1: Geodetic survey of an outcrop for road cut design part of Analyzing High Resolution Topography with TLS and SfM
Yonathan Admassu (James Madison University) John Paul Ligush (James Madison University) Matthew Gribbin (James Madison University)
This unit offers an alternative application for high-resolution topographic data from an outcrop. Using engineering geology methods and data collection from TLS and/or SfM, students design safe "road ...

Unit 3: Getting started with GPS data part of GPS, Strain, and Earthquakes
Vince Cronin, Baylor University (Vince_Cronin@baylor.edu) Phil Resor, Wesleyan University (presor@wesleyan.edu)
This unit provides essential background information on GPS (global positioning system) and reference frames. Students learn how to access GPS location and velocity data from the Network of the Americas (NOTA). They ...

Unit 4: Geomorphic change detection part of Analyzing High Resolution Topography with TLS and SfM
Kate Shervais (UNAVCO) J. Ramon Arrowsmith (Arizona State University) Nathan Niemi (University of Michigan) Marin Clark (University of Michigan) Chris Crosby (UNAVCO)
Applications of geodetic imaging in geomorphology research often center on monitoring and detecting change within a system over time. Since most geomorphic systems evolve over longer time periods—months, years, ...

Unit 3: Geodetic survey of a fault scarp part of Analyzing High Resolution Topography with TLS and SfM
Bruce Douglas (Indiana University) Nicholas Pinter (University of California Davis) Nathan Niemi (University of Michigan) J. Ramon Arrowsmith (Arizona State University) Kate Shervais (UNAVCO) Chris Crosby (EarthScope)
In this unit, students will design a survey (TLS and/or SfM) of a fault scarp. After conducting the survey in the field, students will analyze the data to identify the number and magnitude of possible fault ...

Unit 2: Geodetic survey of an outcrop for stratigraphic analysis part of Analyzing High Resolution Topography with TLS and SfM
Bruce Douglas (Indiana University) Chris Crosby (UNAVCO) Kate Shervais (UNAVCO)
Geodetic survey techniques, such as TLS and SfM featured here, have many applications in sedimentology research, including lithological identification and analysis, sediment surface topography, and sequence ...

Unit 1-TLS: Introduction to TLS part of Analyzing High Resolution Topography with TLS and SfM
Bruce Douglas (Indiana University) Chris Crosby (UNAVCO) David Phillips (UNAVCO) Kate Shervais (UNAVCO)
Field experience using geodetic and geophysical tools provides a unique opportunity for upper-level undergraduates to learn research skills applicable to their future graduate research or career path. This unit ...
