- This week we test Drone LiDAR and its ability to see through trees! Fly with me as I explore an Ozark forest to demonstrate the effectiveness of using an unmanned aircraft system with LiDAR to create a bare earth model. The challenge is real as I tackle the dense Ozark foliage to determine what lies beneath the tree canopies and brush.

Hi, just wanted to share how much I appreciated this video! I have a DJI Phantom 4 Pro enroute (first drone) because I want to map out several of my properties...~and this video gave me some really good things to research. Much appreciated!
Thank you!
I am looking a type of drone that would be able to do exactly what you demonstrated in your video. Truly awesome and thank you very much for the top presentation 🤩
We can help you out! Please contact us and we will schedule a meeting to dicuss further: www.rockrobotic.com/talk-to-sales
hi there im nathan and im from Trinidad and Tobago ..... so HI FROM TRINIDAD AND TOBAGO . I have some questions concerning the use of drones in land surveying . Im 18 years old and now about to start my degree in geomatics and im pretty new to the entire land surveying scene and my first questions is other than volumetric data collection and topographic map use can liDAR or even drone technology be used in cadastral and boundary surveying and can you (if possible ) talk about like a list of application for drones in surveying( liDAR or otherwise) and where can one go to learn and train to use drones for this field . I wanna learn drone surveying because in my country is 10 years back in technology and i would like to be one of the person to introduce this sort of technology Also(if possible) can u talk about what you do in general like overally as a job. So yh . And apart from the question i must commend you on the quality of your videos its truly top notch and i love it . I hope your channels grows to insane numbers because more ppl need to see this content its truly amazing
Which lidar system do you use? What software do you use to process data? What's your educational background? Awesome video! Keep up the good work :]
I also wonder these questions.
Nice view man, great job!
Does the data is downloadable?
I'm surprised that in all the comments, nobody asked if the lidar surface was tested for vertical accuracy. The surfaces look nice but are they? I see spikes and piles and can't be sure if the ground classification totally worked. Please also speak to how much manual editing of the classified point cloud was required to remover erroneous ground classifications.
Good Job. Lots of Love Man ❤
Really enjoying your videos! Great job
Great tech but still a lot of noise in that model. Would be nice to see some independent verifications of the actual ground surface in that area.
Yeah definitely a lot of noise in this heavily vegetated area. Most of that is low laying vegetation on the ground. We have a runway that is very very very flat that we are going to test all the equipment on. Over 200 survey points!
Nice videos, i dont know how i found this channel but i subscribed :D
Y’all are awesome
Great video! What program did you use there to analyze the LiDAR data?
Hey Jason how's it going? Likewise super appreciate your work and personality. Question for you... how much is that Drone with Lidar set up? Thanks!!!
Awesome! Tech in state of the art
Soo Cool! Possum is the man! Sweet shots on the river!!
Nice work guys!
Job well done guys
Thank you - be sure to check out some of my new content! And subscribe to the channel!
Great!
Why you don't use the Livox?
Super dense my ash! Nuthin compared to some places where I've been.
Lidar or Camera which best
Hey mate, how do you actually classify the data? Do you have a video on the process?
Check out the rock cloud
Great, nice video.
I'm sorry, I have one question what's the different types sensor with hydrographic lidar ?
Think you're talking about bathymetric lidar which uses 532nm wavelength laser, these lasers use around 1100nm laser. Need more power also in bathymetry because the pulse needs to fight through the water and back, much tougher medium.
Could you please share which equipment you used including software? I need to get similar equipment for an archeological project. Thanks
You should check out the new ROCK Robotic R360 LiDAR - www.rockrobotic.com/r360
ROCK Cloud LiDAR Data Processing Software - www.rockrobotic.com/rockcloud
You might need to fix your quadcopter drone - the rolling shutter artifact is a sign of quite some vibrations it is experiencing. Perhaps unbalanced props?
Are there different strengths in lasers for different sensors? Would that affect vegetation penetration?
Yeah that's the big issue we're having at my work. The drone is not lidar and the vegetation creates a terrible surface model that we can't work with. Love this though. Well done.
Hey, great job guys 🙂
Yeah, the big fixed wing has my attention.
I have a lot of old video of flying this system. Maybe I should upload a small compilation video...What do you think
Hi, what software did you use in this video?
Which LiDAR sensor you used on this video? Thanks.
Hey man! Can this also be used like finding a wreckage of a plane from a thick mountain??
As long as the wreckage is not under the ground, very possible!
Those ground points look great! What software do you use to process the data?
Rock cloud software. Check it out
What makes the ground classified points, as opposed to some other classification? Is it just because they are the lowest ones?

Wow, Could lidar see ruins under tree canopy our structure slightly underground?
Lidar would be useful to identify areas that might have subsurface features, at which point you could send a ground crew with GPR
Did you check elevation some how ?
How do you set up your datum when importing your data? do you still need to find a monument ?
Hey Alfonso! Please feel free to bring any of your questions to our discussion board at community.rockrobotic.com - you can find answers and get help there.
Recomended lidar low budget?
Yes please email me at Harrison@theindianadrones.com
Could they use this as a searching tool to locate missing people in dense forests?
Unfortunately, Aerial LiDAR does not effectively capture humans.
Can lidar be used for active track ?
Thanks for the comment! This is a feature I am unsure about. I want to say YES! because I have seen the agriculture drone from DJI using their radar to maintain a very close proximity to the ground. Let's get to the bottom of this! I will ask some of my friends at DJI. Does anyone else have an idea?
How would vehicles / people register on that LIDAR ?
Vehicles could potentially be seen through the vegetation. However, people would not identify well.
Would lidar be able to find an abandoned car underneath this canopy?
It definitely possible. It would depend on the extreme of the conditions.
Can I join with you! I have an interest here and I learn this job.
Can it penetrate through the ground down to 20 feet?
LiDAR does not penetrate through the ground. However, ground penetrating Radar does.
Would you recommend to me which GPR is most likely to give me best results?
Wow I know this is 3 years ago, but your statement has not been CORRECTED "How a LiDAR Drone Maps the Bare Earth through trees!" The earth for instance is not bare in a forest ,the bare earth is covered in fallen leaves branches etc, furthermore you imply Lidar sees THRU' vegetation ie in total. It is true it can get thru' voids. However Vegetation still has to be removed in the model and contours have to be extrapolated between reflected points. Lidar is great if correctly applied
Hi i sent you an email regarding a quote or distributor where i can buy the Livox and Liari V for a m210.
I am based in Cape Town.
Please get back to me
Thanks for reaching out! I just sent a response! Can't wait to share with you about some new products we are seeing hot the market! The market is changing quick!
What about the vegetation? I am really interested how to measure trees. It would be awesome if you could make a video about that.

@@IndianaDrones Thank you :)
At 3:13 I thought godzilla was somewhere taking its atomic breath
How can we connect I am from india
hello@rockrobotic.com
What kind of schooling do you need for a career doing this ?
It’s it available in india…
Thanks for inquiring! Reaching out to a ROCK LiDAR Expert would be the best way to get proper information. Please write to, sales@rockrobotic.com - so we can help get you answers.
Damn dude how tall are you?
TALL
I am millionaire because of you 🙏🤑
You are still incorrect, Lidar cannot SEE THROUGH TREES, it certainly cannot determine bare earth. If you are standing in a forest and and can see light shining , that is when Lidar can measure. As to Bare earth, sorry, forests are full of detritus from fallen leaves, branches and undergrowth. The perception that LIDAR can see thru vegetation is putting people on a expensive path. Lidar is useful for planning in forested areas , followed up by photogrammetry which is more accurate after clearing. Some Lidar is very good on structures , by this I mean Terrestrial Lidar. Also we use terrestrial in vegetated areas, under canopy, which is very effective in eliminating trees.
We've tested this against survey grade ground control points and check points... this is consistently better than photogrammetry. And yes, we know how LiDAR works!
@@IndianaDrones You are misleading people and that is a fact
so youre the reason they cut down the forrest for construction is what your saying?
