    Matrice 4E - camera settings in mission for photogrammetry

    My preference is 20 mph maximum for any height. Again, your results may vary.

    Map Flown...."Report" - Choose C1 or C2 (Review Now)

    This thread and your answer were perfectly timed. I had just asked this question to myself on how to view the after route report at a later time. Thank you!

    Matrice 4E - camera settings in mission for photogrammetry

    It sets the focus to manual by itself on a photogrammetry mission. When it gets to the start point, watch it. It will look down at the ground, auto focus and then switch to manual infinity. I have found better accuracy at checkpoints with a maximum of 20mph, but your results could be different...

    Change photo storage to SD card or find better way to get photos/videos off the drone.

    I just take out the SD card, place it in an adapter and put into my PC. You can also use a high quality, data capable USB A to USB C, with the C to the drone and the A to a PC. Make sure the drone is turned on.

    Terrain following

    I am not sure of the speed when using terrain following, but I would only use a high resolution DEM. The DEMs from DJI are of lower resolution and dated, at least that's what's been reported from some users.

    M4T Incorrect altitude in photo properties

    Terrain data is a downloaded DEM (Digital Elevation Model) to allow you to use Terrain Following when mapping. The DEM's from DJI can be old and of low resolution. This has nothing to do with images reporting in ellipsoid for altitude. The drone uses either the barometer, VPS or GNSS module for...

    M4T Incorrect altitude in photo properties

    Information on DJI RTK drones and how they report their altitudes: https://www.agisoftmetashape.com/how-to-process-dji-rtk-coordinate-data-in-agisoft-metashape-complete-workflow-guide/#:~:text=Common%20Issues%20When%20Using%20DJI,to%20apply%20GCPs%20for%20correction...

    M4T Incorrect altitude in photo properties

    Your flight logs will show altitude as above the takeoff point and this in the metadata will be Relative Altitude. Relative Altitude is in the metadata, photo properties just does not use it. To answer your question on adding 40m, no, the drone is calculating the altitude as designed and...

    Metallic noise coming from props?

    Is it the intermittent squeaking sound? If so I can hear it. Hope it isn't bad bearings. Do you have access to a thermal camera to check if one motor is appreciably hotter than the others?

    M4T Incorrect altitude in photo properties

    The altitude in the image is referring to the HAE or Height Above Ellipsoid. So the 118 means that your drone was 118 meters above the WGS 80 ellipsoid. DJI Enterprise drones that have the ability to use RTK will report two altitudes. In the Matrice 4 Series metadata: HAE will be in the...

    Metallic noise coming from props?

    I am tone deaf. I don't hear anything. You would of noted if you had any errors on screen. Rotate the motors around and make sure the little gap towards the bottom is even through a full rotation and that you can feel the magnets making little stops. On a side note, this drone looks bad a**...

    RC Plus Controller Updated Firmware, Aircraft did not

    Not on mine. My controller firmware is 01.64.0605. Like you my Pilot 2 is 15.0.0.8.

    M4E mapping wide lens

    The images do seem more compressed than the Mavic 3E. Are you on the newest firmware? I just went back and looked at a lot of my images. They range from 5MB to 11MB with the 5 being streets and roads and the higher numbers being forested areas. Someone else in the forum also had a problem with...

    M4E mapping wide lens

    You do not want to use the zoom camera for mapping. The Wide is the 4/3 sensor with the mechanical shutter. If you change your zoom you will have a different focal length and this will introduce errors into your outputs. I have an opposite experience. My outputs in Pix4D, Agisoft and Drone...
