Setting Up GCPs For WebODM - An Imperfect Example
In this video you'll join me in the field setting up several Ground Control Point targets for a small build site we're documenting. The setup isn't perfect as we're not using a mapping or survey grade GPS to mark the targets. The point of this video is to show you the process of capturing GCPs for your modeling efforts with WebODM.
We used a Mavic 2 Pro for this video, and an iPhone 8 with Map Pilot Pro, and an iPhone 8+ as our GPS. If you're serious about modeling and using Ground Control Points you'll be wanting a better GPS setup, or something like the Phantom 4 RTK unit.
