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 ...

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 ...

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
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.

Detecting Cascadia's changing shape with GPS | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
Research-grade Global Positioning Systems (GPS) allow students to deduce that Earth's crust is changing shape in measurable ways. From data gathered by EarthScope's Plate Boundary Observatory, students discover that the Pacific Northwest of the United States and coastal British Columbia — the Cascadia region - are geologically active: tectonic plates move and collide; they shift and buckle; continental crust deforms; regions warp; rocks crumple, bend, and will break.

Measuring Ground Motion with GPS: How GPS Works
Shelley E Olds, EarthScope Consortium
With printouts of typical GPS velocity vectors found near different tectonic boundaries and models of a GPS station, demonstrate how GPS work to measure ground motion.GPS velocity vectors point in the direction that a GPS station moves as the ground it is anchored to moves. The length of a velocity vector corresponds to the rate of motion. GPS velocity vectors thus provide useful information for how Earth's crust deforms in different tectonic settings.

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
Learners use the GPS Velocity Viewer, or the included map packet to visualize relationships between earthquakes, volcanoes, and plate boundaries as a jigsaw activity.

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.

Reconnaissance stratigraphy and mapping of the Frying Pan Gulch, MT
Sinan Akciz, California State University-Fullerton
Students are required to create a reconnaissance geologic map and report for a small area (approximately 0.5 sq. mile) Frying Pan Gulch just NW of Dillon, Montana. This project is designed to make students familiar ...

Mid-Atlantic Appalachian Orogen Traverse – Field Trip 1
Steve Whitmeyer, James Madison University
The Mid-Atlantic Appalachian Orogen Traverse is a series of 4 virtual field trips that cross the Blue Ridge and Valley and Ridge geologic provinces in northwestern Virginia and northeastern West Virginia. This ...

Geologic Mapping of a Virtual Landscape II - Three River Hills
Mark Helper, The University of Texas at Austin
This second virtual mapping exercise builds on the first (Geologic Mapping of a Virtual Landscape), but contains a more complicated geological puzzle to solve. This virtual landscape is also much larger, with a ...
