Okmok volcano in the Aleutian Islands had a large eruption in 2008, which created a new volcanic cone. Since then, the cone has been eroding rapidly. We are trying to quantify this erosion, and we want to do this using sets of photos we collected from a helicopter in 2021, 2022, and 2023. We will create three-dimensional digital topography maps of the volcanic cone that formed during the 2008 eruption. The student will use the technique of Structure from Motion and photogrammetry, and tools such as GIS, to create the maps.
