Title

Modelling Topography With Drone Photography

Abstract

This past summer I researched the optimal UAV parameters to create 3D models of the landscape using structure from motion. Optimization allows for more efficient use of field time and better resolution of geologic structure within a surveyed site. We chose our two study locations, Ankeny Field and the Twin Sisters area in Wallula Gap, because Ankeny is primarily a low-relief location, whereas Twin Sisters is high relief. We concluded that we should fly 10-20m above the highest point in a survey site to achieve optimal resolution; this meant 40m on Ankeny and 80m in Wallula Gap. From this process we were able to achieve average resolutions between 2.5 and 5 centimeters.
