Surveying a Lake: A Guide to Collecting and Presenting Drone Data for Clients

[@christianmarcella1809]

Love all your videos, whenever I get discouraged in the surveying field I can pop over to one of your videos and feel that excitement again. Also that program Skand seems very user friendly

[@Feelthefx]

It’s always wise to have a hard hat on in the woods. You never know when a branch will break off or birds attack

[@RamiTamimi]

Hahahaha. My relationship with PPE is so split, but I have to respect a site’s rules.

[@U00000010B]

Thanks for the video. What vertical datum did you use? Did you convert the GNSS ellipsoid height to orthometric height for your final report?

[@landsurveyor77]

When shooting in the photo control points wouldn’t it be better practice to use a bipod and get three rounds of 60 sec observations in the am and pm to average out any errors.

[@skandioau]

As always great Job Rami !!👌👍

[@kekpeziezoke964]

You are really doing well what camara do you use please

[@jasonoh5489]

Love the video. Can Drone Deploy do the exact same in terms of deliverables to a client? That's we use to process our ortho mosaics.

[@isg_jsy]

Hey Rami, are you using Ntrip network to pull the gcps? Just got a reach rs2+ and trying to figure it all out, just about got my head above water 😂 alot to take in. If your using Ntrip when you pull the points do you wait for a fixed reading, then take the coordinates? Thanks

[@jle1981]

Would it have been beneficial if you had take a couple of spot elevation checks at edge of water while you were setting Ariel targets?

[@chamofer]

Hola desde Colombia, me gustó mucho el bastón de topografia que usas, me puedes indicar donde lo puedo conseguir. Gracias

[@wzfellguard1]

Thanks for gear channel, you are doing gear o/ from Europe. Also any other option instead of Skand that you use / others ? Like its 1300euros for a year.. Is there any free/limited/cheaper version

[@williamhollingworth4747]

Great video! Awesome work!

[@aldima2405]

Is there a good fix in the bushes? Are you building a flight mission in the DJI pilot? How long did it take to fly ? Is there enough battery? Have you tried the DJI Terra program?

[@RamiTamimi]

There was some struggle in the tree, but only a few minutes until I had a fixed reading. Missions were done on DJI Pilot. The project took about 45 minutes to fly. I have limited experience with Terra.

[@chaseg.2592]

Hey, great video! Was curious where you got you targets from? They seem super easy to setup and most likely get you great elevations since they are hard. I have been using the new Mavic 3 and it’s amazing! Thanks!

[@highlight9014]

I think they are just plastic bucket lids painted up to look like a target. Easy to make.

[@citizenraf]

😁я уже подумал, сейчас будет батиметрическая съемка )))

[@Dustmadeout]

Nice! The only problem is video quality, it almost looks like the upscale from 480p to 1080p.

[@Devikmsw]

Hi Where is ur base station? I mean , how did get gcp points with single receiver?

[@penananuba]

What brand of GNSS Receiver of that?

[@billyandriam]

Hi! How long will it take to take the coordinates of those GCP if you live in an area where you don't have CORS/correction services avalaible for that RS2 receiver?

[@RamiTamimi]

If you have a second GNSS receiver then you can set up your own Base Station. Watch this video to learn how - kzbin.info/www/bejne/iJyTaqKDecR8aJY

[@bowenwang4198]

Great video! I'm a little confused. Shouldn't the elevations of water surface be all the same?

[@ingedgarv]

waiting for the answer, but in short i think yes, water tends to level by itself. At the beggining i thought he was going to do Bathymetry.

[@landmeterbeuckx4779]

are those gcp's self made?

[@commonsenselogic]

I thought the reason for RTK is so you don't have to place GCP's?

[@TheAussieRepairGuy]

Might need to close the aperture or add an ND filter to that camera, exposure is way too short and makes the video chunky.

[@aqeelnahi8470]

@Rami Tamimi , well done bro , I am living in WA and would like to start my own drone business ; what's your advices ? I know how to do the work (Flying&Processing) I am working on my DP certificate.

[@nanirayavarapu8763]

I have a huge Issue with Matic when it comes to roof edges or walls or any 2D objects. They're blurry, noise and looks super UGLY. What's your experience in using Matic to generate ortho when flown over buildings and boundary walls. Please let me know.

[@RamiTamimi]

Make sure you set the correct template. Matic has alot of menus to pick from to achieve your desired outcome.

[@nanirayavarapu8763]

@@RamiTamimi I have tried with several surface smoothing values. Still of no use. Roof edges must be sharp enough. As a matter of fact any 2D objects must sharp enough in ortho so i can use them to measure. So i was wondering if you had any luck with the matic when generating ortho of urban areas that had roof edges, fencing walls etc....

[@sylvaingiroux9741]

Great job

[@randalltollison1917]

How do you fly over water without getting spikes in your model from reflection?

[@nanirayavarapu8763]

I face the same issue. Used Matic, Mapper...Wondering if someone figured out the solution....

[@iamrelient3011]

Its not really "possible". You will always have holes in your point cloud with water since it moves and there isnt many differences in the surface. Best way I have found is fly at a higher altitude and gather as much shore as possible in each image

[@ivanyakymiv6680]

if the task is to determine the water level in the lake, then what is the point of conducting time-consuming photogrammetric surveying, if it would be possible to simply measure 5 or 6 points of the water cut with a rover?

[@RamiTamimi]

I was demonstrating the annotation feature on Skand. My client requested a point cloud so that's why I went through the process of using a drone to survey.

[@kyletalbot6580]

On a small body of water such as this wouldn't it be smarter to shoot the elevation with your GPS and carry that elevation around the lake? Water should be relatively level.

[@RamiTamimi]

Yes that is an option. There were some spots that would be hard to reach, but the real reason I used a drone was the client also wanted a PC and Ortho.

[@kyletalbot6580]

@@RamiTamimi 👍We've done jobs before where we drone the entire area like you did. Use pix4d to extract the shoreline then complete and drop in a bathymetry survey. Always looks amazing in CAD

[@informativelessons3939]

Hello sir I want to learn drone survey

[@bucksandducksroe]

Or you could run a level loop in 15 minutes that is way more accurate.

[@sprasadksp]

Hello Rami , I am a freelancer I work on ortho, mapping, lidar and uav data too . I will be providing outputs like orthophoto,DEM ,DSM, colour point cloud, CONTOURS and MAPPING.and data matching with gcp also.please contact if u need any DATA SET to be processed.

[@Emmanuelzimba-n4f]

Hey, can you help me with the name of the software that was used to convert the data?

[@eprohoda]

thank you. how stunning job~want more followers?, bye~😍
