[@bigmurph762]

@@jwmj2897 Real pricing is so hard to find man. And what you do find is all over the place. They'll say things like "$30 - $160 an acre depending" or "$99 - $240/hr depending" But they wont break down what depending is. Personally, I have been laughed at for a quote and been told I was cheap for the same type/size quote. I made $1300 to record raw video of a RV park. I made $150 taking pics of a house for a realtor. I made $3500 for making a map of a corridor that was 6 miles long and 120' wide. So....good luck. And you find a magical price sheet for drone services please let me know!

Happy to see someone spreading awareness of our industry. I just flew a Powerline mission and currently processing the data.

[@DylanGorman]

Powerline data is my favorite. I have a video I am working on to show that exact data set off as well.

[@kevinkasp]

This is like what computers with Excel and estimating software that can read AutoCad files has done to the construction industry. When I got out of college in the early 80's it could take three trained professional construction estimators, two or three weeks to go through 50 huge sheets of blue prints and a 300 page spec book from the architects in order to put together an estimate and submit a bid to do the construction of a million-dollar-plus construction project. The cost of doing the estimate itself has to be added to the price of the construction project - maybe 350 man hours. Now, one man does the same thing in one single day. It's totally a win-win for everybody on multiple levels. Three weeks is chopped off of the process which cuts three weeks of interest-carry on the loan the real estate developer has, the construction company can have a much higher mark-up on it's estimating cost because it's still going to be only a fraction of the price of what it used to be. Instead of three men, full time, estimating 20 projects a year to bid on, one man can do 200. Lidar, post processing software, and high performance drones can do the same thing to the surveying industry.

[@DylanGorman]

You summed it up perfectly. We are working on some of the biggest projects ever in a much smaller/ condensed timeline compared to traditional methods of capturing this data!

Hello. Great video. I’m not sure why you use both the drtk-2 and the Emlid RS2. If you are running a PPK process with the RS2 why bother with the DRTK-2 as well? I run the L1 on my M300 and I use the RTK on the drone with an NTRIP service. Works great. Really curious why you double up on the RS2 and DRTK-2

[@jupitereye4322]

How much can you increase the accuracy by adding more GNSS heads? And does the wind have an impact on accuracy? Even if it moves these heads 0.5cm, does that have any effect?

[@vctrgallardo]

Question. Do I have to be a licensed land surveyor in order to capture LiDAR? If so, what steps can I take in order to go down this career path?

[@DylanGorman]

You do not need to be a licensed surveyor to capture LiDAR at all. You can do the data collection for a surveyor but they will need to check it and approve it before it can be used for that line of work.

[@htune754]

do you need any other certifications outside of the part107

[@LightPleasures]

Nice video Dylan. I've been researching Lidar for some time now and even this exact same setup. So how much of a learning curve was it when you got the M300+Lidar? I've done photogrammetry in the past.

[@DylanGorman]

To be 100% honest, it took a few flights and a lot of mistakes (in processing and understanding the more technical parts of the data analysis). Capturing the data is by far the easiest part to be fair though.

[@DimmyV]

Love this video Dylan, thanks for sharing your insights.

[@Dustmadeout]

How exactly does an optical system like LiDAR see through the vegetation?

[@zerogee9864]

Think about archaeology, especially in open desert areas. It's an inexpensive way of finding straight lines that can indicate ancient buildings at or below ground level. Works a charm in forested areas, jungles and the like... worldwide. Now it's cheap enough for smaller projects or difficult to reach areas. Good job!

What are your thoughts on bathymetric lidar? Shallow underwater mapping could be awesome.

[@sethlynch89]

There's a channel "adventures with purpose" that searches in water for lost cars and helps solve cold cases. I sent them info on it and they loved it. Being able to find targets faster and have a clearer picture could be big!

[@DylanGorman]

Oooo, we actually have a bathymetric sensor but haven't put it to use yet. As for a bathymetric LiDAR sensor, that works a bit more differently than the typical sonar based system that we have (and is also like $250K just for the LiDAR version of that sensor). If I get a chance to play with one I will 10000% make a video about it because that's something I have always wanted to play with!

[@DylanGorman]

Thanks for watching!

[@SamaraMedia]

Great informative video Dylan. Just out of curiosity, the R2A comes with a 24mp Sony camera integrated into the LIDAR package, why not use the photos captured with that rather than fly a separate mission using the P1? Was that for comparative purposes for those using traditional photogrammetry methods to capture survey data?

[@DylanGorman]

It was more of a comparison between LiDAR data and Photogrammetry data for surface penetration. The colorized point cloud shown on the LiDAR data was from the 24mp Sony sensor that is on there so theoretically we can process orthos with those without a second flight needed.

[@cascadestreamsolutions4211]

John - I can't speak to why Dylan reflies an area with the P1, but I can say why I do. I have a GVI LV70 with a Sony 24 mp Nex camera and a separate P1 payload. The P1 photos are far superior to the Sony. If I want colorized LiDAR I can do it in LiGeo. Yes it increases the collection time, but for my purposes it isn't a significant cost. Also, the P1 can collect data at twice the speed or more than the LV70. GVI recommends a velocity of about 5 m/s and flight heights of 60 m or less. One can fly with a P1 at 120 m at a speed of 13 m/s. The downside of the P1 is the file size. Orthomosaics can be 10 gb or more, so I use GeoExpress to convert them to sid format to use in Civil 3D, ArcMap, or QGIS. I think it comes down to what meets your needs. Also, the GVI LV70, which looks remarkably similar to the Rockrobotics and a few other LiDAR units, there is a slight shift in the orthophoto because the GPS is based on the LiDAR sensor not the camera.

[@DylanGorman]

@@cascadestreamsolutions4211 loved this explanation. I haven’t tired combining my ortho data from the P1 with the Rock Robotics LiDAR data yet, I might have to try it out!

Your description of the project It seems to me you will need to be on the same data as FEMA. to determine the true BFE (Base Flood Elevation). for the buildable areas.

So i'm only using the RS2 for my PPK process, I am using the controls that the survey company sent over to tie all my data to which is what I did in Rock Cloud. I set up my re projection in the same state-plane/ datum in order for the deliverable to line up properly with FEMA's data. I hope that answers that question?

Ive offered LiDAR consulting, sales, service and training for years. To be successful in sUAS LiDAR, you must have substantial contacts in the respective industries that have a need for it. I focus primarily in surveying, construction and civil engineering and I have customers that bill well over $1,000,000 a year (small, ‘mom and pop’ customers at that); i agree 100% with what Doug is saying….the data is like gold to a lot of companies. However, you must have the contacts to make it work. For a good, mid range sUAS solution you’re going to be in the 100k range. Add another 15 to 25k for equipment to shoot ground shots and a computer that can process it (your off the shelf Best Buy computer will not handle these datasets). Good luck!

[@DylanGorman]

Depends on the deliverables you are promising to send. I would never say its a survey grade deliverable since you aren't a surveyor. I would learn towards a highly accurate model rather than survey model.

[@cascadestreamsolutions4211]

Check the state regulations you want to provide data in. In CA and OR, licensed civil engineers and surveyors can collect topographic data and sell it. I'm not sure how many licensed surveyors or engineers are going to accept responsibility for the data someone else collects without a rigorous QA/QC effort.

[@caasinauj]

Not many licensed surveyors would take responsibility. I can see some of the contours are being "pulled" due to lack of proper grade breaks. In TX topographic data is not regulated by the state board so engineers use this type of data since they place a disclaimer to match to existing grade on their construction plans.

[@richardnewcombe8397]

As per usual, thank you Dylan! What are the differences or drawback from using an M30 instead? It sounds like the M30 is a third of the price or the 300 with payload.

[@airartisan]

M30 does not have detachable cameras at all. You cannot use the R2A system with the M30 as it does not have a skyport adapter.

[@DylanGorman]

Richard, this is exactly what I was going to say. M30 is built more for search and rescue where M300 RTK is built for pilots like us that want to run all kinds of sensors (with the ease of use being DJI platform).

[@airartisan]

Good video explaining the niches of the technology. A word of caution for those wanting to hop on the bandwagon. Be very cognizant of state laws where you are operating. Legally where I do business with Lidar Technology, all controls and deliverables MUST be approved and certified by a Land Surveyor or Engineer to be used! You cannot just go do the scan, set your own control and sell to these companies who want this data. It will be worthless to them or you will be taken to court for Surveying without a license from the state board you are flying in. I have heard horror stories about lots of unlicensed work going on where surveyors are being approached randomly to certify data they didn't collect. Not good for our business!

[@DylanGorman]

Hey Matt, great point you brought up here that I forgot to mention in the video. Every state does have its own laws regarding selling and distributing "survey" grade data. I did try and mention that if you are not a surveyor to either work with one or only use this data as a "construction" layout model as you can easily get yourself tied up into some legal trouble if you present that data improperly.

[@airartisan]

@@DylanGorman I would highly advise to not even present the data as a construction layout model to a general contractor. Once again you will assume high levels of liability risk by doing so. Unless you work with an engineer/surveyor, you cannot provide topographic data. The only good the data does for you is a reality capture asset that can be used to create a digital twin for an artistic type of market place. Now structure inspections on the other hand are a bit of a different animal. There is much more room for growth in those industries for independent pilots. Places like solar panel farms, tower and roof inspections, powerline modeling for local municipalities.

How much might a large company pay for this? I’d assume you aren’t charging hourly and you can price estimate a job?

how exactly are you able to afford a 50 thousand dollar lidar and a 30,000 dollar drone..

I really wish you would stop defining photogrammetry so generically. You clearly have no idea of the capabilities/performance of high end professional aerial photogrammetry, and repeatedly class photogrammetry only from the consumer "point and squirt" entry point, which has become popular due to consumer drones and entry level software packages that do little more than render the image over a poor TIN/DEM. Good videos Dylan and again, I congratulate you for doing what you do and love your passion for it... but please, understand there is a vast range in photogrammetry and I've personally used all of it from state-of-the-art (in all it's steps, from the 80's to now) in aerial, satellite, terrestrial, stereo, analytical to digital all the way to multi image, measuring F1 race cars and space craft to tens of microns... MICRONS! Rant over... keep up the good work!

I do have a vast knowledge in photogrammetry as well. This video was aiming to show off the now more accessible forms of data capture with LiDAR as well as how simple I can be. Photogrammetry still has its place and we still do a lot of mapping for it.

Measuring to 0.0001 with photogrammetry? I want to hear more please.

[@AthleteGalaxy-oh9xm]

Clients pay for this service This guy I work for willing to pay 20,000.00 -30,000.00 to do LiDAR. Real s**t

[@ThingEngineer]

Curious, do you find your Army Corps of Engineers work on sam.gov? There have been a few of them on there recently and one right now in the Jacksonville District.

[@DylanGorman]

This one was through a personal relationship that I have with the developer. The Army Corps of Engineers were already involved on this project. I just happen to have LiDAR capabilities in the area to be able to provide the data that they were looking for!

Dylan, Have you seen that many commenters on this video (including me) have gotten a message from "Dylan Gorman" informing them they just won 2 DJI Mini Pro 3s? The message says to send them a DM on Telegram (a messaging service that it seems all of Russia is using these days). I did so. I got an immediate response asking me for my complete name, email address, mailing address, and cell phone number.
