    M4T RTK accurate or not ..

    The whole test was difficult. I tried 3 times to start it, but being 0.5 miles from the ocean had sea fog drifting in and out. While running the test a cold front was moving in and I literally had patches of fog occasionally blowing over my head. A child at one point grabbed a control point and...

    M4T RTK accurate or not ..

    For our European friends, this chart is in centimeters.

    M4T RTK accurate or not ..

    The results are in. I used Agisoft Metashape Pro. I also ran the Matrice 4T in Pix4Dmapper and got very similar results for the nadir mission with Altitude Optimization and no GCPs. My RTK base is also 19 km away, so the M4T will need a test with a base on site, since the 19km is 19 ppm or...

    Mapping Question

    I did the above with both a 4T and 4E recently. Does it fly the whole entire perimeter or does it fly from the outside of the perimeter to the center of the map? If so, it is flying an Altitude Optimization route of 1 line of oblique images from the outside to the center.

    Mapping Question

    I just did this. I created a simple polygon in Google Earth. I right clicked on the polygon and Save Place as and chose KML as the file type. I placed the KML on an SD card. On the RC Plus 2 in Flight Routes I pressed +. Then choose the KML option. I then designed a Area Route/Mapping mission...

    Newb - Just bought my M4T and have questions

    The image quality on this drone while good for its intended purpose of inspection and mapping, will not be on par with something like a Mavic 4 Pro and the camera has limited options compared to the Mavic 4 Pro. You cannot change the aspect ratio. You cannot change to DNG. To delete the drawn...

    M4T RTK accurate or not ..

    Others have posted about this. I will see if I can change to the larger 48MP images, but I don't think it is possible. I do know that the Mavic 2 Enterprise Advanced does use the larger image size for mapping. But the image sizes slow down the processing by a large factor and in previous tests...

    M4T RTK accurate or not ..

    Dave, the Agisoft outputs will have multiple chunks as I play around with each dataset. I will most likely know what the M4T outcome will be before the test. While the test will need a lot of time to setup the control points, I will most likely have time this week to have the M4T fly and map...

    Just got the M4T

    Welcome and congratulations on your new aircraft. The Matrice 4T is a powerful Enterprise drone that performs like a much more expensive drone. You might want to start by fully reading both the User Manual and Maintenance Manual so that you can know about all of its features and know how to...

    M4T RTK accurate or not ..

    Update. I have received the drone. Wow, what a great thermal solution. The thermal image, while being the same resolution as my Mavic 2 Enterprise Advanced, definitely has software enhancement and possibly is an upgraded sensor, especially with the Ultra/Super Resolution enabled. We are still...

    M4T RTK accurate or not ..

    Mflyer, on this test I may not get a chance with multiple speeds on the 4T, but you can be certain that I will be testing the 4T in mapping and modeling constantly, so I will have this information in the near future. I chose 15 mph since it should help the 4T with Rolling Shutter distortion. I...

    M4T RTK accurate or not ..

    I plan on the following for my test. The drone should be here on Wednesday and hopefully within a week I can find time to do a test. Drones in test. Matrice 4E Matrice 4T Mavic 2 Enterprise Advanced Mavic 3E Phantom 4 RTK All drones will receive corrections from my RTK subscription service...

    Automated mission with spotlight

    No, I have not tried any automated mission at night. I am interested in others' answers though. DJI states that the vision positioning and obstacle avoidance need at least urban type lighting (street lights). Would turning off obstacle avoidance help in this situation? I know for safety it...

    M4T RTK accurate or not ..

    I just purchased a Matrice 4T. Is was a very hard decision between the dock version and the normal 4T. It has not shipped yet, but hopefully soon. I will have a mapping competition between the Matrice 4E, Matrice 4T and the Phantom 4 RTK and post the results. All drones will be receiving...

    .

    You can run this with Smart Oblique, nadir with altitude optimization (1 flight line of oblique from outside to center) or even with double grid oblique. If you run double grid oblique you do not need the overlap listed since oblique images contain so much more of the scene in each image. I run...
