Skyris utilized a 3D Drone Scan on a large natural landslide that has shown recent signs of movement in the Alsea, OR area. This particular landslide threatens an $8.5 million research fish hatchery run by the Oregon Department of Fish and Wildlife.
We utilized three batteries in the DJI Phantom 4 Pro to collected 1,050 images. Then the software we use matches at least 10,000 pixels of overlap between each photo. Utilizing triangulation, the software calculates each pixel’s precise location in 3D space. At this point some heavy math and photogrammetry processing takes over for several hours and the final output is a 3D point-cloud comprised of over 800,000,000 data points. The relative accuracy of the 3D Aerial Drone model is sub-centimeter. The purpose of this exercise is to document existing conditions and monitor movements, if any in this massive slide.

3D Drone Scan Results
With the full project link users are able to make precise measurements from this 3D Drone Scan including: distance, area and volume. They are then able to annotate, share and place benchmarks on the movement. Web viewing of a maximum of 20 million points is currently a constraint of the web application. All 3D drone scan high resolution points are visible and measurable on Skyris and client local systems.
Skyris has 5+ years experience in 3D Drone Scanning applications utilizing the principles of photogrammetry. Our clients utilize this tool for stockpile accounting, land use planning, inspection and documentation for legal and insurance claims.
