How to be a Drone Mapping Pro | Deep Dive

If you want to know more about Drone Mapping & Drone Survey's this is the ultimate guide for you. Dave King breaks down every element of mapping including which drones to use for 2D & 3D maps, which drone equipment to use for Survey work, and what all the work flow processes to consider for Drone Mapping. We review Drone processing software as well as the validation processes that are essential to make sure the drone data collected is as expected.

Thanks for free education! This is part of the industry I'd love to grow into. Currently I'm isolated into drone video work, and have yet for any requests for use of my M3T.

Thank you for a very intersting video. Our survey clients are civil engineers and architecs and they still expect a 3d cad deliverable with line/feature work for track edges, drain hatches, fences and so om (with height annotation) so we still have to walk and measure those features with an RTK pole. If tracks continue under dense tree canopy then we have to continue with total station. That said they still like to see an ecw/geo tiff in XREF to that cad. For us the strength of drone survey is in large areas of rough hillside and here we can use point cloud ground extraction to create DTM and contours to merge with the conventional data. I agree about the eye watering cost of Trimble kit but it offers a fully integrated approach. All the project data RTK / total station or even point cloud laser scans are recorded to a single project on a very robust controller. Relatively recent introduction of the M3E has been fanstastic and seamless. I can use Trimnle VRS with my phone as hotspot to the DJI controller. If there is no phone signal I can use the R10 NTRIP correction for the drone. However the really big bonus of the R10 is that if there is no phone signal at all you can still get a true base position using about 4 minutes or so of RTX correction. It works very well and you can check at night with a proper PP static solution against local CORS RINEX in TBC. (I am aware of some UK surveyors getting inaccurate results using Opus.) The limitation with the R10 base on wifi NTRIP is that you can only control the drone from a position within wifi range of the base. If you are climbing rough mountain side that is some very heavy kit to transport. I would say we still need a lightweight base (which could still double as a rover), capable of getting a position by RTX, and then creating an NTRIP correction for the drone.

Glad to know about the Reach RTK stations, thanks!

Im just gettinv into drone and drone work i came accross your channel and im a new subscriber thanks for all tje great info

[ickn]

This will show my ignorance of the industry. But I don't understand how one can make enough money to even purchase this equipment. I've always heard surveyors make great money, but still. Thank you for the video and your time; I have much to reflect on.

[Rogun]

You guys always have great info for the layman.

[jamescashregisteredbuildin]

Great video and presentation, thank you, as I'm only starting to get into drone work

[gunzowillis]

Great Video. Well done. Do you have one showing the limits of each type of drone

[kreativekraal]

Thank you so much for sharing. I'm a newbie in the mapping and surveying industry. I'd definitely learn a lot from your channel. keep the videos coming. Are there any books that you can recommend? God bless you and your family.
Much love from South Africa.

[Anonymous_Whisper]

How much is the entire set up you mentioned cost break down?

[gk]

Thank you for your work and advise. What a pity you are too far to access your services. Would be great to subscribe to your video training database.

[samiutenkichrononauta]

can you explain why some people use free rtk services and other people use their own rtk ground stations? What's the difference when making maps like photogrammetry? Is it needed to use your own rtk when making lidar data and not needed at all when making plain maps?

[thijsrinkel]

Nice Video. Do you also make gcp’s or control points when using ntrip? Just to verify the data I assume then?

[jybyrd]

I hand made my GCPs, 2x2 panels from Home Depot I colored green and black checker board with a number on them. Total cost per GCP was about $20

[tomthomsen]

Don't forget to mention that in some states it is illegal to solicit mapping services if you're not a Licinced Land Surveyor. Some states may still allow it but that's slowly changing.

THANKS FOR THE DROM GUIDANCE I LOVE THE DROMS I LOVE THE MINI DROM 4 PRO. I WANT ONE.

[ibrahimvandy]

Wow nice lecture
I would love to do an online course with you guys
What are they things involve

[kamilmaz-ej]

It’s great vid and so many useful info here! Thank you for great job! Just quick question, I seen some good drones there, but also one small one. Would you recommend to go with air2s or rather one of minis at the beginning of journey? I know m3e is best on market because of shutter but it will be next atep to buy better than air2s or one of minis, I am curious about your opinion ;) thanks!

[kamilmaz-ej]

2:21 where is it from, is it related to some software?

[kianteck]

Hi Dave, great video. Thanks. Im from Singapore. Im a dji drone hobbyist for 4 years and I’m thinking to start a mapping and facade inspection business. What would be the est start up cost on all the necessary equipments. Im looking at Mavic 3 enterprise or thermal.
How much is pix4dmapper? How abt hammer missions?
Looking fwd for your advice.
