4. Context – Background & Definition Why using drones? • Need to document projects from above the eye level • Benefit of generating relatively accurate data via photogrammetry and LiDAR. • Public Outreach for transparency on projects. What about photogrammetry? Where do I find it used? • The science of making measurements from photographs. • Input – Photographs • Output – map, drawing, imagery, point cloud, 3D Mesh 3 City of Austin | Public Works Department
5. Tools of the Trade - Drones Considerations using drones for photogrammetry • Environment the drones will be used – Safety First. • Applications the drones will be used for – Safety First. • Pilot training – Safety First. • Output data – Hardware and Software. • Productivity – Post Processing. What drones to use • Consumer drones – DJI Phantom, Inspire, Mavic and 3DR • Industrial drones – DJI Matrice series • Platform solutions – SiteScan, PrecisionHawk and more 4 City of Austin | Public Works Department
