    This was such a good and useful video. We have both an R10 and an R12, do you have any experience with the DJI D-RTK how it compares with the Trimble products with the M3E workflow? We are planning on buying a M3E and trying to sort out the details yet. Which software do you prefer for processing? We currently have Trimble Business Center but open to other options as well.

      Thank you for the feedback! We only use Trimble rovers. All of our surveyors have trimble rovers and haven't considered the DJI D-RTK. If you end up going down that route, it would be great to get your feedback!

    Hey Harry! Could you please elaborate on what you mean by "block shifting to an absolute location" if you are not near a known benchmark? Thanks!!

    • @harrymacpherson-wood
      @harrymacpherson-wood 5 місяців тому

      Hi Mary, Block shifting would be where you treat you data as a single piece and shift / move / scale (but not contort, or twist) to survey ground control points placed on the ground. If you don't have surveyed ground control points you won't be able to block shift it to a datum. Does this help? Thanks, Harry

      If you have the GNSS unit turned on and have not changed the standard settings it should all be as per the video. Unless you have a GNSS rover which isn't base compatible?

  • @stuartross1081
    @stuartross1081 6 місяців тому

    Thankyou very much for that for that. I appreciate it takes a lot of effort to assemble a video like this. I have a similar workflow. However, I typically set up my base first thing to allow me to do conventional RTK work , road edges hatches, and so on with another pole mounted receiver. (which provides valuable check points later). I will get my true base station position doing a short session of VRS or RTX then use that position to start it as a base. I don't use "Here point" anymore as it took too long to sort out afterwards. The issue I have run into is that the moment you configure the R10 as a base with Trimble Access and start transmitting corrections that 3.2 setting is lost. It is possible to link to the base with a browseer while it is already transmitting a radio correction and reset it to 3.2 again. Its clever, in that it retains the coordinate, antenna height and radio correction. If youu have colleagues working up the hill from you on RTK rovers you don't disrupt them. The correction from the R10 to DJI is really strong and solid in my experience and those check points on hatches and the like bear this out. I've had astonishly good results. I noted you were over writing the VRS RTK settings in DJI to accepr R10 instead. I found this a nuisance if regularly jumping between the two and kept a laminated printed sheet with respective settings in the box. To their credit DJI have fixed this now and you can save each profile with a name and select it as you desire. I do like the VRS when the site is favoured with phone signal as you can fly the drone as long as you have your hotspot phone in your pocket (Much lighter and less restrictive than carrying an R10 across the mountain side). I thought you may find this of interest.

      Kia ora! Great video from Harry and a great comment from you. Something I have noticed, which ties into your comment. If I set my base over a known Co-ordinate and start the base in Trimble Access, it auto populates the reference station. I find using lat long a pain as we work so much in NEZ. Could you confirm your workflow aligns with mine. 1, Set up base over a known Co-ordinate 2, Through Trimble Access, select Measure, RTK, select control point, Start base. 3, Connect to Web GUI via controller, update the RTCM to be 3.x (seems to change back to 2 automatically) 4, Ensure RTK connection and fly away? John.

      @@HG-Reality-Capture That's a really handy tip, thank you. Next time we setup using a base station I will see if it connects as per your process mentioned. When we have control points in Trimble Access, we normally change the settings to represent lat and long. Definitely would be a good idea if we could leave it to our preferred Easting Northing. Thanks for commenting

      ​@@HG-Reality-CaptureI have read your notes through and I think our work flow is identical. I get good support from our Trimble dealer here in Scotland. Each time you use Access to configure base it resets that 3.x. If you use e, n, h as long as your transformation parameters are correct it will broadcast correct late long ht to feed drone. I always have check points scattered across site to check for blunders but I find R10 correction is better than VRS but this is the same for conventional pole work.

    Not through the DJI controller. As far as I am aware you can only record your photo positions using RTK. If you want to further post process you can use third party software; for example LiDAR post processing to update the image file locations. Is that what you were asking?

      @@rapturemusicartist9348 Because the rover does not record the data but the controller does. The only way I see you being able to record a RINEX project is through the Trimble controller (meaning you treat your flight not as an RTK but PPK mission). You can export job files in the Trimble controller to get RINEX files.
