These are a few example UAS mapping projects that I have completed.
All end products seen were created using UAS imagery collected from a DJI phantom 4.
Candelaria Trailhead
Imagery was collected via DJI Mavic Pro. A seamless orthomoasic was created with an extremely high image resolution.
Pix4D is a paid application, however this was done with a free trial. WebDOM is a free open source application. Each application was run on similar settings to create an equal comparison. All imagery was collected via DJI Mavic Pro.
