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

12. Publishing Data
    How and where do we publish the data?
    • Photogrammetric models – 3D PDFs, ArcScene Packages
    • 3D Meshes – 3D Visualization Software (Infraworks, etc…)
    • Point Cloud Data – Sampled classified rasters or LAS files.
    • Planimetrics & Quantities – ESRI or AutoCAD files.
