    • Topographic survey of the Nooksack River using structure from motion photogrammetry, September 2015

    Metadata Updated: July 6, 2024

    Structure from motion photogrammetry was used to contruct a digital elevation model of the Nooksack River based on images acquired on September 15, 2015. Images were acquired using a Ricoh GR II camera mounted in a near-nadir orientation in the wing of a fixed-wing aircraft, flying approximately 1,500' above ground level. Ground control consisted of 53 chalked X's on gravel surfaces, with centriod positions measured using RTK-GNSS. All photo and ground control processing was performed in Agisoft Photoscan
