Getting started with Structure from Motion (SfM) photogrammetry
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 ...

Volcano Monitoring with GPS: Westdahl Volcano Alaska
Learners use graphs of GPS position data to determine how the shape of Westdahl Volcano, Alaska is changing. If the flanks of a volcano swell or recede, it is a potential indication of magma movement and changing ...

Exploring Tectonic Motions with GPS
Using a map showing the horizontal velocities of GPS stations in the Plate Boundary Observatory and other GPS networks in Alaska and Western United States, students are able to describe the motions in different regions by interpreting the vectors resulting from long-term high-precision Global Positioning System (GPS) data.

Measuring Ground Motion with GPS: How GPS Works
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.
