Great content Dave!
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.
Our Pleasure.
good luck my brother. You and i are on the same route
You guys always have great info for the layman.
thank you
Great, as always.
thanks.
Great explanation, thanks.
Great video and presentation, thank you, as I'm only starting to get into drone work
Glad to know about the Reach RTK stations, thanks!
They are really a great option.
Great video. Thanks, Dave.
Our pleasure.
Great Video. Well done. Do you have one showing the limits of each type of drone
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.
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.
We could make hours of content on true Survey workflow but that's not what this video is for. It was an introduction to what true Drone Mapping on a professional level includes.
@StuartRoss1081 Thanks for taking time to give additional info and commentary on this great video. Good information shared, brings Relief!
@@powerfullaudmarcus2455 Sure thing, our pleasure.
The prblem I see with inexperienced non-surveyor individuals is that they believe they are getting great data (sub-tenth verticle data) because the system is advertised that way. There's way too many things that go into what the ultimate accuracy will be to just make a blanket statement like that. One company, that I will not name, claims ALTA accuracy. I can tell that when the point cloud doesn't match your ground shots on concrete by 0.20' horizontally, it's not ALTA quality. A recent project of ours has some great results but every once in a while......bam! 0.50' verticle error as compared to the total station. Civils and Atchitects generally need much better than that especially where ADA issues exist! My two cents.
Great stuff
great video mate
Thank you Mathew
THANKS FOR THE DROM GUIDANCE I LOVE THE DROMS I LOVE THE MINI DROM 4 PRO. I WANT ONE.
Thank you!
Our pleasure.
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.
As a young man 25 y.o without any specialization is it possible to start this work by just buying one of these drones ? Or do i need to study something in particular and having a lot of connections ?
Wow nice lecture
I would love to do an online course with you guys
What are they things involve
Stay tuned we will release when its ready.
What would a beginner do in order to start something like this? I have a Mavic 3 pro, Mini 3 pro and the Air 2s. What kind of industry would be best to start at?
We cover the equipment in the video. Industries for drone mapping are in the Survey, Engineering, and construction fields.
Mind if I ask, does emlid and rover replace a dji rtk station if you put gcps down?
Yes we cover that in the video.
Are you using those base stations and ground control points even with RTK unit?
Yes
I own a GNSS receiver with a VRS service and a DJI Mavic 2 zoom drone. So i would only need to lay down some GCP s and will get accurate map? Whats the cost effective postproccessing software to mess around and test how it all works?
A GNSS receiver will only help you using an aircraft that has RTK compatibility. You could fly your missions without RTK and tie the accuracy locations in better with 5 to 8 GPC points. Pix4D is the industry standard for Post Processing software for Survey accuracy.
DJI Mavic 2 zoom would nt be a good drone for mapping. Mavic 2 pro would be a good for beginners and small projects. You want a camera that has a mechanical shutter like the old phantom 4 pro RTK or the Mavic 3E
@@vp62ift Mavic 2 pro has also electronical shutter. You mean better because it has 20mp photos instead of 12 like with Zoom?
can I do this type of drone mapping using a mavic 3 pro? it has no SDK available yet therefore i'm asking
You can create pre-programmed automated flights with most drones including M3 however you will need to lay down ground control points and check shots.
Did I understand correctly, that you need a minimum of 3 aeropoints? or GCP in general? Such as 1 aeropoint and 2 GCPs? I spoke to propeller last week, they explained that the standard is still 1 Aeropoint per 100 acres surveyed. Which makes sense since they are a PPK Service.
We used to be a propeller customer. We got amazing results with 1 aeropoint on surveys of +/- 100 acres.
The reason we left the platform is just the annual recurring cost.
I am also curious, Why 2 Emlids? In Ohio, PA, WV you can access CORS. You can use the one Emlid setup as a rover connected to CORS and set a known point (for the base function) and record all of your GCP's Then setup over that known point as a base with the same unit, no?
Hello - Pix4D recommends a minimum of 5 GPC's and will not process any project with less than 3 GPC's. An aeropoint is a portable GPC. So factor a minimum of 5 GPC with 2 to 3 checkpoints. 2 Emlids are needed for a base-rover configuration to measure GPC-checkpoints. For flying you would use one over a known point that can broadcast the data out to the Drone over NTRIP. Hope this helps.
@@SteelCityDrones Thanks Dave, So to be clear. You don't need 5 aeropoints. You could use 1 aeropoint and place 3 or 4 other GCP's. Correct? I assumed when you were talking about Propellers aeropoints you were also using the propeller platform.
I'm also curious on your thoughts of using a long static recording and OPUS vs connecting to a CORs network and being able to record a corrected point in a fraction of the time?
You are correct, in that your method would require 2 Emlids. With CORs readily available in most areas (and free to use in some states) curious why not use this method? It would save a bunch of time rather than taking 2 hour static point observations
@@importjunky3106 That pretty much is NTRIP which can range from free up to $400 a month. ODOT is free, and you will get a corrected position quick but depends how accurate you need to be, a network point will never be as accurate as a post processed point.
I did enjjoy your video!
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.
You gotta be kidding me! Mapping and Land Surveying is two different things! A Orthomosaic doesn't establish boundaries what so ever! It's simply a aerial photo.
But that brings up a good point. Be cautious of the terms you use and be sure the customer understands the difference.
What state is it you refer to?
Do you have to have survey license? Or someone sign off ?
Good question. It varies in the location you live in and from state to state in the US. Mapping, while traditionally part of the surveyors realm in the field, is more an engineering survey and not one requiring property delineation or decision making. Photogrammetrist are not necessarily surveyors, nor engineers, I can tell you that here in PA, it is illegal to "advertise" services such as "Survey Services". The define of Survey services includes "The professional services, such as establishing property/boundary lines is the main issue that has to be done by a licensed surveyor. A person with experience staking out roads or sewer systems is not required to be registered. There are survey techs that go out and capture and measure data with rovers and they don't need to be licensed either and it is not illegal to provide a customer with drone pictures and deliverables. People been doing that with planes for the longest time. A First Amendment lawsuit in North Carolina says surveyors cannot stop drone operators from selling photos and making maps. We strongly recommend to check with the state and or region you live in as the law can vary from state to state.
The purpose of a surveylicense, in essence, is to protect the public in situation where they are not covered by the law of contract. Your neighbor, or the guy down the street, may have their boundaries adversely affected by the surveyor’s work, if it is deficient, but they have no recourse against the surveyor under contract, as there was no contract, implied or explicit, between them. They have recourse under the law of torts in the event that things go wrong, but the idea of the license is to ensure that this is as rare an event as possible.
Drone operators should make claims about what they are imaging or claims about the location of boundaries. Their work has as much impact on your boundaries as your granny snapping a photo of your home from the street.
With all that said, everything that we mention in the video above are processes to assure that if you do give a client deliverables with will go toward someone else doing the official survey work that the GeoData is as good as it can possibly be to survey standards.
@@SteelCityDrones Real bad idea to provide services that are traditionally done by a licensed surveyor (insured) if you're not one. There's a lot that can go wrong data wise and the inexperienced guy would never know what to check or how to correct bad data. We've had services provide ortho and point cloud data to us from our photos and control that was terrible. We re-shot all of the control and were sub-hundredth on all of them. The engineer using the data would never know if his design really works until construction staking occurs. Case in point. A recent project, flown by others, ended up with contours that were 0.55' off on average, The targets and Benchmark were checked and found to be good at the time of staking. over 2000 cubic yards extra had to be removed from the site because the design was based on bad contours. Guess who is being sued right right now? That's right, the guy that provided the aerial data. Plus, everyone involved is pissed at him and he won't be involved in projects like this one in the future.
@@tomthomsen11 There is nothing wrong with educating people on how to collect the data and then validate the data properly. The idea behind this video is to dispel the myths that an overwhelming amount of drone pilots about the perception of what the actual work flow is for collecting data properly. Many people feel all they need is to buy a $3500 drone and maybe an RTK module and they can provide clients with survey grade data. Also I would disagree that only licensed surveyors are the only ones to collect the data and set control. Survey tech's do this all the time and they don't have a survey license. Drone pilots can do this as well as long as they are properly trained and educated which is what we want to do.
Does the M3T support PPK
PPK requires a mapping drone to take advantage of it.
@@SteelCityDrones so something like the M3 and M30?
@@christianmartinez6492 Mavic 3 enterprise, matrice350.
Where is the drone mapping and surveying course?
We are about 1 month away from having it available.
@@SteelCityDronesGreat, looking forward to it!
This is what I need for Africa! Drone Mapping and Photogrammetry. You just earned another subscriber. Any possibility of taking me on as an apprentice to go on field trips with you, in order to implement your best practices in Africa? Thanks for your consideration. #AfricanStoriesRetold
Confused vs work flow and steps, show a presso as well vs just video talking
@koolkiwkat This video is not a mapping or survey class.It's an introduction to knowing what it takes to do this line of work that reviews the proper equipment and workflow processes needed to ensure that the data you collect is accurate and can be verified. Can you tell me what material in the video is confusing?
Once again, a sales guy in front of a gnss set-up. Totally credible. Listen to these boneheads sell you overpriced gimmicks and misunderstood workflows.
