See that's where your messing up already. You gotta innovate to get the best workout experience

You need to use something like this and let its position be controlled by donations. 10$ per CM traveled and 5$ per degrees for the camera angle/tilt

Phantom 4's are starting to get hard to find so snag one if you see the unit itself for less than $1,600. All the accessories and 3 extra batteries should be around $500. Make sure you don't get the "+" model.

You know Pix4D so as far as GCP's we use inexpensive 5 gallon bucket lit with the center painted black. We like orange as there is next to nothing in nature that color so it stands out well in many scenarios. You should be able to find them for around $1.60 each so you can stock up for little cost. They are also inexpensive enough that if it is an ongoing project you can leave them there.

For survey equipment I would recommend the Emlid RS2's. If you have RTK network services then you will only need 1 receiver as a rover. It doesn't look like Ontario has very good coverage except the southern edge. I would contact a nearby Land Surveyor. If you cannot find a service then you will need a 2nd receiver to act as a base station. Receivers are $2,500 each so you can ROI that pretty quickly against renting equipment.

I'd say that would put you around $5k and the re-occurring cost of Pix4D and the network corrections services. The RTK networks are usually between $500-1,500/year.

That's the + models and the RTK. The regular V2's are getting hard to find!
