@@GM6DroneMapping I won't forget! Maybe I'll get some extra attractive behind the scenes footage and send you a direct link lol. Hopefully I'll be at more construction sites than beaches but this past summer I actually did both. Major Beach replenishment projects here which I shot a lot of and found pretty interesting. Hope to have an informational video about that done soon. Unfortunately the timing never worked out for me to be able to shoot the guys who were surveying in the water. I met them one morning after I had used up my batteries and the other times I went they didn't happen to be there :-( By the way, the hopper dredge ship that looks to be a couple hundred yards off shore is actually much further away. it's a pretty big boat so the scale is deceiving. I did get out there, get some shots and get back without any issues but I was surprised how far away it was...

Thank you for sharing your knowledge and experience. I have been using DroneDeploy on a trial basis. Let me ask, is there any particular reasons that you chose Pix4D? It is certainly much more expensive than DD. I could not afford Pix4D at this time. Thanks!

Thomas Rayborn thank you, I appreciate your comment. I have actually switched to Agisoft Photoscan a while back. Its expensive too, but processing locally on your own system gives you the freedom to correct your maps and models when there is a problem with the images. DD has 1 way to process and if your map fails you have to re-fly. Plus I can handle bigger data sets on my system and I can use ground control points without paying more money. Overall its gives me more options for every thing.

@GM6DroneMapping

Yes, i have more control over the project settings. In DD you dont set up anything. If your project fails you have to go re-fly it. However, if DD is working for you and saves money, stick with what works.

Muy bueno. Espero poder dedicarme a esto muy pronto

How much should one expect to spend on a monthly subscription to pix4d or other programs you had mentioned. DroneDeploy is very expensive if you opt for the package that allows exporting various file types.

@GM6DroneMapping

6 жыл бұрын

Thats a very good question. Pix4D at minimum is $350USD a month. Agisoft Photoscan is $3500 USD for a 1 time license.

This video is really cool. As far as measurements are concerned, it's now possible to perform them together with photogrammetry in a new cloud-based platform dedicated to drone data: delair.ai.

You have confirmed everything I've experienced so far in drone mapping. There is no one size fits solution. Each platform has certain pros and cons. Anyhow I'm getting ready out here in California to test out 3dr by site scan. Runs on the same pix4d engine. I'm teaching myself how to make holgramic 3d animated models all in VR. Hope that makes sense?

Are the videos in Drone Mapping from A to Z in the order that you recommend to watch them in? If not, could you suggest to order to watch these videos in?

I probably need to clean up the order but they go in order from newest to oldest. Meaning, it would probably be best to start at the oldest first.

What types of drone-based mapping can be accomplished without GCPs?

@GM6DroneMapping

6 жыл бұрын

Any of it really, accurate is relative. If you're not a surveyor then your map can't be used for an official purpose. The question becomes, how accurate does the client need it to be. You can make the map very accurate even without GCPs

@chrisalexander2478

@@GM6DroneMapping What methods would you use for that? Several scale constraints in leu of GCPs to force the map a touch in the x, y, and z?

@GM6DroneMapping

5 жыл бұрын

Possibly yes. If an object can be measured physically then It can be constrained. However for the Z a gcp would be needed. But if correct altitude is needed then it goes back to your point. GCPs and check points are needed

What is the maximum accuracy that you have achieved using a P4P?

I believe that it was 3in/7.62cm that is without any control points. With control, I don't remember but it has always been better than the requirements for that job.

@@chrisalexander2478 I don't suppose you can. Unless you use a scale constraint in the software. But that only servers to scale it correctly not verify the global accuracy. I use GCPs without checkpoints when I want the map to be accurate but its not a requirement. Like if I am mapping a construction site as a means of documenting the progress but the client is not using it to verify the contractors measurements. (as an example)
