Some of the few individuals that still motivate me in this field anytime I feel like changing carrier...
Same here
Same here rami channel is another level , don’t stop sir.
There’s a lot of days I feel like starting a different carrier when working by muself
You've really helped me in this. You kinda motivate me and i know some others too. Such a sweet profession 😌
You deserve all the words of thanks, thank you very much
السلام عليكم انا اخوك من المغرب امارس نفس المهنة
When will the link be added? I'd love to see what it looks like as a processed product.
Great video. Liked and Subbed. Looking forward to upcoming content.
Was this an RTK mission? I’m assuming it was not, I know that you used an RTK phantom but was this post processed using your GCP’s? I’m trying to understand. Is there a video where you explain this particular workflow and which software you’re using? Thanks so much for these amazing videos.
RTK it s a method of survey using the satellites for positioning in the real time. Basically what he did was surveying the land, collecting all the data and using the ground control points he georeferenced his project later.
Piggy-backing off @Alex Botea, Rami's drone is capable of RTK but he likely performed post processing (PPK). The drone captures a log in RINEX format and of course the images. He can then take the logs captured via the drone, a base station log and GCP coordinates to obtain relative / absolute accuracy. The software would then update the drone images meta-data with the corrected GPS coordinates. Your photogrammetry software would stitch all of those images together to create one huge image, a 3D point cloud, etc.. The objective is a product having centimeter level accuracy (dependent upon your ground sampling distance (GSD)). He could've also program his drone to use the RTK capabilities via NTRIP as he sometimes does. If he did use the RTK via NTRIP, he likely skipped showing us that part because the video was focused on providing a high-level account of him surveying a land-fill using GCPs. You can find some really detailed, step-by-step tutorials on his channel.
Wonderful video!
Nice to see a landfill right up against some wetlands. lol. Great filming. Nice editing. Good storytelling. Detailed how-to. Engaging. So what's not to like. The music. But that's personal.
Great video!
Good commentary.
Dear thanks for this video, my question is you didn't mention how many GCP you used for this area
I like the way you 'stab' the home cones down like they have spikes on the bottom.. lol. Good video Rami.
I have to assert my dominance of the home point location lol
Hi rami
Thank you for your helpful videos
I wondered how fast you processed the photos and prepared dens point cloud
It took me hours to get it done in agi soft metashape
Your fast procces is related to your lap top or the software you use?
Rami! I have found the grail of UA-cam channels dedicated to this. Drone surveying/mapping/photogrammetry has peeked my interest and I want to learn more ASAP! Where do you suggest I get started and can I rent all or most of the equipment like reach rovers and monopods etc?
thank you very much i brachiate what you are doing but can you make a video about how to process image with a control point even with chepest drone that has now rtk reciver
Hi, wondering if you can use the DJI RTK2 Base Station to mark the GCPs? You can connect to cors network in mode 3 to do this I believe. Also, I see the drone had an RTK fix while flying. What were you connected to? Thanks
I see that you push down on your targets when taking the GCP shot. How do you match up the elevation to the shot. I always assumed I needed to have the center of the target at the same height? Or was the elevation tolerance for the project not that restrictive?
Wow!
Hi great video, quick question. The flight you took was following terrain elevation or static at 70m?
Can you survey using a basic drone? like DJI Mini 2? Paired with an RTK of course
Hi does the survey have a scale factor of 1 or are you inputting true co-ordinates for the control points. I would like to get into using drones but my sites are smaller and will be in urban areas.
Awesome work, my question is what your marketing strategy to obtain consistent work? Outside your channel.
@Rami Tamimi... could you please do a video on what deilverables the engineers or surveyors are interested in and how they prefer to have those deliverables sent to them...... thanks
Great video idea!
@@RamiTamimi appreciate your insight as an experienced surveyor, the better we can understand what engineers and surveyors are looking for that will help us in mission planning and processing to give them what they need and understand how its useful to deliver that data to them for them to use... great job on your videos 👍
Great video! What is a typical cost point per acre for something like this with GCP’s?
It really depends on the location and complexity of the project.
Nice
Any software you recommend when processing drone data
Rami. Love your channel. I want to get started by renting some equipment to practice. Would you recommend this? If so what do I start with? So far I have Mavic2Pro and software. I think I need GCPs, surveying tripods and I found a place that rents Reach rs. Need some guidance please!! Thank you.
Question on where you know to put the GCPs? Does the engineer have posts showing where they are do you just out the target? Then i see you save the GCPs on emlid flow correct? Thab how do you put it to the remote control so the drone knows how to fly it? Would be great of a more detailed showing how to save amd capture GCPs, how you got to the GCPs targets, how you installed the coordinates to the remote control?
Hey, I really appreciate your videos about drone surveys!
I had a question in mind, what is the usual format of data sought by most of the customers? Do you give them the data in point cloud form or something else?
Some like the RAW point clouds, others want a site with complete feature extraction done.
@@RamiTamimi I see, thank you
Hello Rami, Can you provide me with an idea of how much you are generally charging on a mapped area of 100 acres using GCPs? What was the deliverable? Thanks!!
What prism pole/rod are you using in this video? Never seen one quite like that and I think I want one.
Where did you get those GCPs? How much did it cost?
Hi, what app do you use for drone photogrammetry?
Questions i really enjoy watching your videos, how do you charge? Im trying to implement it for my business but i have no idea what to charge. Per acre ?
Nice. couple questions, how were the points established...predetermined?, random?, boundary?, previously surveyed?, points where straight lines changed direction?
second question, why didn't you set up the base gnss receiver for cm accuracy?
He's using state plane system. He's setting random points in relation to that. From my experience this data is not tied into the actual deeded Boundary. It never shows him locating property corners.
The location of the points were somewhat random, but they are spread out. Meaning I made sure there were points along the outside of the project, and points at the highest and lowest points. I am not doing a boundary survey, so I am just mapping the areas that were requested by the client. I don't use a local base station, I connect through NTRIP to the Michigan CORS network for my corrections.
@@RamiTamimi For just mapping projects, not surveys, do you feel most clients accept around 1 to 2.5 foot accuracy levels. I am not a registered surveyor, but I have been in GIS for over 25 years, so I don't want to present or offer cm accuracy levels. My EVO II Pro Enterprise will produce 1 to 2.5 foot horizontal accuracy with a RTK unit and NOT connected to NTRIP. Yes, vertical is adjusted to best local source found.
Hey Rami,
Am architect here wanting to be able to survey a rocky plot of land of around 500-3000m2 with a point cloud with color - an automatic meshing would be nice as well. And margin of error under 5cm. Can you point to a video about this or a product on the market? Price is a criteria od course. I don't have $30k to burn on it.

Hi sir. Do still using a base on survey?
Hello at 7:31 you have a 70m and 7 m/s, at 9:21 you have shoter speed from 1/500 to 1/200. But for a good image (motion blur) you must take a shooter speed 1/700 or mor short!
any chance i could have the point cloud? I'de like to play with itbin cyclone 3dr. Thanks.
does this still need a base station ?
How accurate is the pointcloud?
Hi which link should I go to see this data set .
Pls do some land survey with PPK and DJI Matrice 350 RTK + L2, it will be very useful
Hello. Could you tell me what is this model of telescopic pole or could you help to chose any telescopic? Thank you
How can I get OBS flight log in Dji non RTK drone
I enjoy watching your stuff but some of your GCP’s were so bad , at least I got a chuckle out of it 😂. Thanks
Flight altitude?
Maybe fly first if wind is going to increase, then survey ground control.
Globally, just a presence of calibrated TS in a company, that's not bad😂
I use PIX4Dmapper to process with data, but vegetation really bothers me. Do I need to use PIX4Dmatic for better terrain?
You need to switch to LiDAR to remove vegetation. That is one of the major limitations of photogrammetry. Do a search on LiDAR sensors.
@@droneviewgis6699 and a fat bank account to get that sensor
How many batteries in total did the drone use and did it automatically come back for battery change?
I used 3 batteries for this site, and yes the drone automatically saves its location, flies back to the home point, and launches again back to its last position.
It’s a great video… But the Wingtra GEN two will crush that this 12 hour day would be done in a single mission… and it does direct PPK output with no GCPs
is this a topographical survey?
How many ground control pints did you use in total
For this project, I used 13 points.
@@RamiTamimi did you use GNSS base station or just the rover??
Hii, u guys also conduct relocation survey in your country?
I do all kinds of Surveys!
@@RamiTamimi what country are u from
@@RamiTamimi You still accept isolated surveys from clients ?
это очень красиво снято, бывала я на практике связанной с этими дронами, и как вспомню потом все это обрабатывать аш дурно становится

Probably good for volumetric calculations but for an actual survey, does not determine property boundary, pick up hidden utilities in weeds, buried drainage pipe sizes/types, headwalls, utilities, tree caliper and species, etc. It has it's limitations. We've used these on gas well pads and still have to go out and field edit.
i need to send a smartphone holder for you my friend
Hello 👋
you threw me off when you picked up those gear spikes............
Haha yeah I bought regular spikes, not gear spikes.

Is this a driving channel??
what laptop you use and what the name of the software
i use agisoft and it takes long time to process
I used my desktop with a RTX 3060. The ThinkPad Yoga X1 is just my field computer.
Altitude?
70 meters AGL
@@RamiTamimi thnx 👍🏻
Where are the examples of Rami's aerial photography projects? In a friendly way, I emailed you to ask for data. Or are you waiting for a personal meeting?! I will be on a business trip to the USA soon, I can meet you in person and tell you what I think of you
Wtf is this first floating gcp ?? 😅
iam a certified drone pilot .please contact for any surveys
Don't use phone when driving please... for everyone's safety.
