Double Hopper Grain Elevator Northeast of Wichita, Kansas.
Pix4Dmapper drone model, locally processed. The aerial camera was from a DJI Phantom 3 Standard.
These photos were taken earlier using Litchi.
I now use Pix4D Capture for drone modeling using either a Phantom 3 Standard and a recently purchased Phantom 4 Advanced.
Litchi waypoint missions are also good for lower angle orbits.
