Just one thing to be very careful, if the base is not set on a known point or get corrections from a server, the relative precision will be good, couple of cm, but the absolute precision, the one that matters when doing a survey, will be 1-3m
Actually that is not entirely correct. The relative precision will be within a couple of cm, that is correct. But to say that the one that matters is your absolute precision is not entirely correct. What I mean is, does the typical user really care where their map as a whole is accurately located on the earth to a couple of centimeters? The answer is no. A typical user does not care if their project as a whole is located on the earth to a couple of centimeters. What a typical user cares about is the relative position to each other. As long as my points are correct to each other to with a couple of centimeters that is what is supremely important. A typical user will not care if the entire project is located to with a couple of centimeters to the correct latitude and longitude on the earth. Only if I was trying to send coordinates for the chimney to send a smart bomb would I care that the absolute point is located. The only flaw in this setup is that your elevation will not necessarily be tied into a local county or state benchmark Hopefully I made myself clear.
Hello, I have a very important question, does the flight planning application have as a system the possibility of adapting to the morphology of the terrain in case of hills and slopes?
Great video! Thanks for uploading this tutorial. I have been very curious as to what exactly the RTK system is and looks like and this video answered those questions! Looking forward to seeing what the post processing video looks like!
'Distortion correction' uses the on-board computer to correct for len distortion. This inital approximate correction makes it harder for subsequent photogrammetry software to then properly correct for lens distortion. For proper surveys you should turn distortion correction off.
Nice video. However, for a complete tuto, You should have told how to set the coordinates of the base station placed above a known point (with measurements of the height of the antenna). Because without this point set up, the mission you did is useless
Hi I'm not satisfied with the quality of the pictures (they seem to be fisheye) how to solve this, some manual settings are needed regarding the focus... as we did on the Phantom 4 pro? Any suggestions on how to improve the image quality?
With the base set up how would the drone handle a tree belt between the base and drone in a mapping situation or if the boundary of survey ran alone side a tree line and the base was obscured
If you are looking to use Topcon Tools for analytics, you will first need to process the imagery with point cloud generation software and transfer the completed map to your preferred analytics software. The Phantom 4 RTK does support PPK post processing if that is what you are referring to.
I'm interested in the same question. I haven't found a way to get RINEX data from the base station. You can export RTCM data but it's in a .dat file format and not typical generic RINEX form. File is similar to a Geomax GPS raw data file but their converter doesn't happen to work for the DJI base file.
@@73Goodfellow yes I second this. Surveyors need a license if they are determining boundaries. Topo, anyone can get that as it’s just an evaluation of the land as is and really isn’t open to legal interpretation
Meanwhile know-nothing bints like Corissa Furr can come in and learn to fly a drone after being hired to be a "product specialist" for you people some years ago. It's funny how women are held to no standards when it comes to being product specialists at trade shows as they don't have to meet the "must know how to operate a UAV/ drone" requirement set forth.
So first make sure you only survey open greenfield sites that are flat and devoid of trees!!!! So it cost a packet and in most places if fing USELESS. PPK all the way.
@@brettjames9088 lets see it work where 90% want to build next to roads people high buildings even low building for that matter. You cannot use a tool that clients rely on and have to turn down most the work or worse attempt it and not be able to deliver. PPK is the best we got at the mo. One broken stream in an RTK flight and its a do over.
@@Guide504 UHF base stations have been used for large civil projects for last 20 years across hundreds of thousands of sites for machine control and rovers. Maybe on a site 30km + you might need a repeater or 2. Also keep in mind graders aren't 120m in the air.
@@Guide504 No shit. The point was something 120m in the air will have far less line of sight issues than a grader on the ground, which has been used very successfully via UHF GNSS for a long time now. I'm guessing you are not a Surveyor.
Thx for this. I just purchased this kit today.

@@MichaelSmith-td7op Hi..so if I use this D-RTK 2 with Zenmuse L2, do I need the known survey point?
Hello, I have a very important question, does the flight planning application have as a system the possibility of adapting to the morphology of the terrain in case of hills and slopes?
Thanks for this. I followed it exactly;y set up my P4 RTK and base Station. Rgds William.
I can't get the app where can i get the app from?
Great video! Thanks for uploading this tutorial. I have been very curious as to what exactly the RTK system is and looks like and this video answered those questions! Looking forward to seeing what the post processing video looks like!
When the postprocessing video will appear?
Very good, what if I need to fly over a farm far a way that is not covered by googles maps?
Thanks for the video! Can you explain why you leave distortion correction and shutter priority off when flight planning?
'Distortion correction' uses the on-board computer to correct for len distortion. This inital approximate correction makes it harder for subsequent photogrammetry software to then properly correct for lens distortion. For proper surveys you should turn distortion correction off.

Yes. I would like to how to use this function as well. I have this at work and a beginner but I would like to use with out GCP's....
how is this done?
Does the D-RTK 2 Mobile Base Station require a monthly data plan? And will I be able to use my Leica GS14 as Base Station with the DJI Phantom 4 RTK?
1st complete video. Please take a video by RTK soft and When the postprocessing video will appear?
Thank so much for the video, very helpful
FOIF A90 gnss receiver also can work with it together
Hi
I'm not satisfied with the quality of the pictures (they seem to be fisheye) how to solve this, some manual settings are needed regarding the focus... as we did on the Phantom 4 pro?
Any suggestions on how to improve the image quality?
Great video and well done !
Thank you for the info .
Amazing stuff
I'm curious to know how to map an area with lots of water. If you're mapping from 10am-3pm then you will get lots of flaring
Does d-rtk 2. Or the ground station come along with the drone. Or do we need to purchase it?
It would have been nice to see a sample of the 2 D product
very good!! thank for your informs
An very good machine
Kindly provide link to the POST PROCESSING of data collected with P4RTK
Very intuitive thank you
With the base set up how would the drone handle a tree belt between the base and drone in a mapping situation or if the boundary of survey ran alone side a tree line and the base was obscured
Thanks for the description, does this model really saves the control points process?... DJI says so... but does it really?
Good video thank you... still w1iting for the processing
Amazing gadget and very pro training. Thanks a lot.
should you use only dji base station? can you use other brands?
says "feet" enters meters. you should change freedom units to normal ones before doing stuff..
Beautiful...
Thanks, excelent video.
Question: Will data picked up by this setup be able to distinguish ground vs vegetation to get topography of a site?
Devi usare un software specifico, come lidar 360 terrain
Which software is good for the RTK
Great video
Now where's the photo stitching video?
Hello, when the postprocessing video will appear?
Can it be used to do a mission without the base station ?
Will the RTK Controller work with a p4p non RTK?
1st complete video. Please take a video by RTK soft.
Great Video 👍🏿 Loved it
grazie !
When is the next video?? We can't wait!
Great video I think I’d like to get into surveying
Congrats for the video, did you know if is posible post process your ground station point in softwares like topcontools?

Udhtd add tho
Don't you need to work under or be a licensed surveyor to legally survey regardless of equipment ?
For boundaries, definitely. But anyone can do topographic surveys if they know how.
@@73Goodfellow yes I second this. Surveyors need a license if they are determining boundaries. Topo, anyone can get that as it’s just an evaluation of the land as is and really isn’t open to legal interpretation
can you please take a video by RTK SOFTWARE?
do we need two d rtk 2 module to use handheld mode .
Thanks
Gracis, una consulta, donde puedo encontrar esa caja rígida para mi phantom 4 rtk?
Cuanto cuestas un systems Asi para agrimensores y donde los vende Gracias.
can you do aggregate or stockpile calcution with the dji phantom 4 rtk without the gnss
Yes you basically just need to use sufficient GCPs to cover the area of the survey
Muy bueno....!!! Gracias
can you show here this mission's map.
How much does this cost
Is it feet or meters that you're entering for the altitude?
The altitude is in metres
Does anyone have price information...
Where can I buy this?
UN FAVOR COMO PUEDO CONVERTIR EL VIDEO EN ESPAÑOL ????
When the next video is coming
Output drawing?
Добавьте пожалуйста русские субтитры
There are no normal princes ...
Qui peut m'offrir un drone et Merci beaucoup❤❤❤❤
