After 50 years of Surveying, starting out with K&E and Gurley transits measuring the horizontal and vertical angles with a vernier scale and measuring linear distances with a steel 200 foot "chain" I am retiring next week. I am saddened to know that I will never get to use these new and exciting technological survey tools. Good Luck to you young people and don't ever let anybody deny you of modern science and progressive thinking !

Can you explain what a ‘return’ is as if I know nothing about this? Because I know nothing about this but find it very interesting.

@PISQUEFrancis Месяц назад

@@13squared2009 a pulse of laser is sent to earth(?), and a return is reflected back to the drone... maybe 1/10,000th of a second ... vert short period of time 500feet to ground then 5000.12 feet back to the drone ... simply speaking ...

Rami - Terrific video as always. I'd love to see (a) how the relative accuracy of the GCP coordinates measured by RTK compares to those measured with a total station and if that would have any effect on the final result, and (b) an accuracy comparison between the drone LiDAR and a series of terrestrial laser scans.

Can you use the pointcloud without DJI Terra? I only have Trimble RealWorks and Agisoft. Will I be able to create a workflow with those?

What software or app does the DJI Matrice 350 RTK with P1 Camera need or use for the auto flight control? We are looking at purchasing that drone for aerial photogrammetry and volumetric surveying at our quarry. We currently have an Ebee Sensefly that uses eMotion software for the flight and then we use Pix4D to process all the data. Does the DJI come with flight software or does something else need to be purchased separately? We plan to continue to use the Pix4D for the final processing.

@seanbrolly3322 4 месяца назад

I know the Matrice 350 RTK can have an accuracy of 1cm + 1ppm Horiz and 1.5cm = 1ppm Vert with the RTK correction. what level of accuracy can the lidar produce in areas of high vegetation using the L2?

@user-yz3ot4yo6j 5 месяцев назад

Hi, how long does the processing usually take?

@keyable 2 месяца назад

Why do we need GCPs when we do RTK survey? I understand it is needed to Check accuracy of the survey, but is it used during processing LiDAR data?

@travisabel4252 12 дней назад

Can the L2 pick up distribution lines also or just the transmission lines? Distribution lines are about 0.04"

Rami, I would like to request a video on making a Custom DSM in DJI Terra to be used for terrain follow. Specifically, I have some landfills I need to lidar this year and they have grown vertically quite a bit since the last Satellite DSM and I would like to maintain the same GSD. I have flown them in the past using photogrammetry and real time terrain follow using a Mavic 3 E. I thought this might be a good tutorial for you to make in a future video given that I cant find much info online concerning that topic.

@jedisdad2265 4 месяца назад

Could this be used to survey a crane runway inside a warehouse?

@g1998k 5 месяцев назад

Dear Rami, can you please clarify whether the MATRIC 350 with L2 can record LIDAR manually WITHOUT a flight plan and whether you can LIDAR the Interior and Exterior of a Building on the same flight and produce a model that includes both WITHOUT requiring two separate flights and models.? I do understand that for practical reasons we do not always have this work flow since the camera cannot scan the full height of an interior floor but we require to have as much information possible on a single model.. Thank you.

@RamiTamimi 5 месяцев назад

You can fly manually. You would have to run the calibration to get the IMU warmed up, and then you'll have about 3 minutes to collect data manually.

@ryanhariskyawan5125 4 месяца назад

To use NTRIP, are you not connecting to your mobile phone hotspot? Or does this new controller have a SIM card slot.

@Rogun987 3 месяца назад

The RC pro controller for the Matrice can use a SIM card or hotspot for internet connection

@maml6479 2 месяца назад

Does DJI Terra process LiDAR on the cloud or a server, or on your machine? If the latter, what computer specs do you have?

@diamondirty4744 5 месяцев назад

brilliant video as always , how would you compare the ROCK r360 to the L2 ?

@RamiTamimi 5 месяцев назад

That would be very interesting 🤔

@diamondirty4744 5 месяцев назад

i guess the key difference is the SLAM enabled feature of the R360@@RamiTamimi

@Rogun987 5 месяцев назад

The R360 has 2 returns vs the L2s 5. but the 360 has SLAM mode which is pretty amazing.

@diamondirty4744 5 месяцев назад

yes i beleive those to be the key differences ,but more shots per return on r360 no ?@@Rogun987
