    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 !

    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.

    Watching your videos for the first time today. Very informative, clear and to the point. I want to sell this equipment to the company I work for. Surveying job sites would be a great time saver, and efficient for accurate material count. One thing I noticed is the drone you are using, and the fact you aren’t wearing a high viz vest? I subscribed to your channel. Keep up the good work.

    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.

    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.

  • @g1998k

    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
      @RamiTamimi  Год 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.
