Research goals of our CAN include developing the infrastructure to effectively generate topography from aerial photographs and integrating this capability into the research of local entities. We also have a goal of integrating these methods into the higher education of Alaskan geoscientists, particularly those from underserved populations. In summer, 2015, we provided two internships to undergraduates in the Alaska Native Science and Engineering Program. The internships are assisting a program for rural Alaskan high school students that trains them to collect images for local environmental research projects (e.g., students from one coastal village are examining the rate of shoreline erosion). The interns are doing proof-of-concept studies to show how the images can be used to derive valuable high-resolution topography. Below, a test site of a local soccer field was imaged using a UAV, and cm-scale topography was derived using â€œstructure-from-motionâ€? software. Structure-from-motion is a technique that uses ray-tracing algorithms to derive shape from multiple images of the same object acquired from different perspectives. The topography was generated at the UAF Photogrammetry Lab that was created through this NASA EPSCoR CAN.
