Getting started with Structure from Motion (SfM) photogrammetry
Beth Pratt-Sitaula, EarthScope Consortium
Structure from Motion (SfM) photogrammetry method uses overlapping images to create a 3D point cloud of an object or landscape. It can be applied to everything from fault scarps to landslides to topography. This ...

Topographic differencing: Earthquake along the Wasatch fault
Chelsea Scott, Arizona State University Campus Immersion
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 4: Measuring Ice Mass Changes: Vertical Bedrock GPS
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
This unit shows how GPS records of bedrock surface elevation may be used to monitor snow and ice loading/unloading on decadal and annual time scales. Students calculate secular trends in the GPS time series and ...

Converging Tectonic Plates Demonstration
Shelley E Olds, EarthScope Consortium
During this demo, participants use springs and a map of the Pacific Northwest with GPS vectors to investigate the stresses and surface expression of subduction zones, specifically the Juan de Fuca plate diving beneath the North American plate.

Unit 1: Climate Change and Sea Level: Who Are the Stakeholders?
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
How are rising sea levels already influencing different regions? This unit offers case study examples for a coastal developing country (Bangladesh), a major coastal urban area (southern California), and an island ...

Working with Point Clouds in CloudCompare and Classifying with CANUPO
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 ...

Unit 5: Societal Implications of Climate Change: Stakeholder Report
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
Sea-level rise due to the melting of glaciers and ice sheets and ocean thermal expansion has significant societal and economic consequences. In this final unit, students prepare a summary of the impacts of sea ...

Unit 2: Examining the Distribution of Mass Wasting Events
Bobak Karimi, Wilkes Community College; Stephen Hughes, University of Puerto Rico-Mayaguez
What factors contribute to the distribution patterns of mass wasting events? In this unit, students will use a frequency-ratio method, one of the most common quantitative methods used in the statistical analysis of ...

Visualizing Relationships with Data: Exploring plate boundaries with Earthquakes, Volcanoes, and GPS Data in the Western U.S. & Alaska | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium; Becca Walker, Mt San Antonio College
Learners use the GPS Velocity Viewer, or the included map packet to visualize relationships between earthquakes, volcanoes, and plate boundaries as a jigsaw activity.

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium; David Thesenga, Alexander Dawson School
This lesson teaches middle and high school students to understand the architecture of GPS—from satellites to research quality stations on the ground. This is done with physical models and a presentation. Then students learn to interpret data for the station's position through time ("time series plots"). Students represent time series data as velocity vectors and add the vectors to create a total horizontal velocity vector. They apply their skills to discover that the Mid-Atlantic Ridge is rifting Iceland. They cement and expand their understanding of GPS data with an abstraction using cars and maps. Finally, they explore GPS vectors in the context of global plate tectonics.
