In min 4:15 it was mentioned that we need to flight the area and then feed the terrain follow a particular DSM file. Q I have is we need to process the captured data from the first flight say using DJI Terra or not to get that TIF file? Thank you.
For Real-Time Follow, the message (see 1:47 of video) asks to enable RTK positioning before performing Terrain Follow. I have the Mavic 3E, but don't have an RTK add-on. Will Real-Time Follow still work or should I not use it? I fly in fairly steep environments.
I just watched this video and it has helped a lot; however, I'm not as strong in my geodetics. I get the horizontal system should be be WGS84(EPSG 4326) but I am not sure which of the options I find under the ellipsoidal option in ESRI's ArcPro 3.3. Can you please specify the option that you think will work best in my Mavic 3E? I presume that it would be World based and not North America based and would be WGS84 (WKID 115700).
We should be able to use LIDAR derived DTM data too and then define a vertical offset to simulate DSM... Is it really safe to base a terrain following flight on a DSM? Vegetation elevation can change elevation substantially from season to season... e.g. bamboo
Depending on flight height and location importing your own data may indeed be the best option. If you wanted to add altitude could adjust flight height and flight height to target surface..
"Currently" only on Enterprise Mavic 3s.....i can see this being a nice addition to the regular Mavic 3s for more cinematic options. Perhaps the first option where it simply uses the downward sensors. Didnt the Mavic Pro or 2 have follow terrain?
As you mentiond flying over DSM is a very essential tools for mapping for max safety and accuracy . BUT why you dont use this option for RTH ? when the mission finish or battery finish Mavic dont return to home over DSM and it has PRESET and optimal RTH mode which both of them has some negative points and causes to decrease safety .
Aircraft: Mavic 3E with active RTK Real-time terrain follow / Terrain follow height: 100m Max. flight altitude: 120m Mission Type: Mapping / 25-35ha of meadows, cornfields and forest Flight area: Lake Constance region (Germany); Starting point in the south of the mapping area (= lower slope) Warning on takeoff: The aircraft is flying in a high altitude zone (500m). Fly carefully. During the mapping flight, the drone suddenly paused and reported "maximum altitude reached". In the first attempt I had planned a forest strip. This seemed logical to me, since the drone would exceed the maximum set flight altitude at 30-40m tree height + 100m flight altitude and this would lead to a conflict. I then threw the forest out of the mapping area. However, it stopped in several places above the grain fields. Only when I dropped from 100 to 90 to 80m with the flight altitude, the mission was completed. Why is that? According to the manual, the drone uses its sensors to scan the terrain in front of it up to 200m in advance and independently follows the course of the terrain. At least that's what I expected. The starting point (lower or upper slope) should not play a role in the variant. But why does it still reach the maximum flight altitude with a buffer of 20m? At another area (flight parameters as above) I was standing on an elevated dirt road and the grain field was a little lower. At my location, a depression was visible in the field. The drone flew its orbits and paused in front of the dip and reported "maximum altitude reached". The sink was "only" 3-4m deep and about 20m long. Here, too, the only thing that helped was reducing the flight altitude to 80m. Does anyone happen to know in which grid (every x meter) the sensors determine the slope of the terrain? Perhaps the sink was not recognized or recorded by the sensors? Has anyone had the error message in principle and a solution ready? Incidentally, the maximum flight altitude was also reached when using the DSM (Aster).
I am having the same issue here. I flew in a hilly terrain. I climbed to the top of the hill after 3 attempts, and it went well after that. What i realized is where i stand to fly is more important as well. That shouldn't be the case at all for using Terrain follow. But it still did. Hope the terrain follow actually works as intended with new updates
Per video it is 30m resolution from satellite data so if there is not significant terrain deviations generally it works quite well though it is important to monitor the drone during flight.
Thanks Kyle. This is much better informative video than the previous one. It really helps a lot.
Thank you! Was looking for this mode for ages, didn’t realize I had to first select AGL before terrain follow option would appear
Nice. The video I was waiting for.
Do you need RTK for terrain follow when you pull the DSM off the internet?

loved to learn from more videos

Looking for clarification on if minimum height for real time follow is 30m or 80m. 80m was said, but the dialog box @2:30 shows 30m.
Saw that! If it was a type error then he did it twice. I'm wondering if he said it wrong. Have you find any info on this?
I Have the M3M, and using real time terrain follow, the minimum height is indeed 30m now.
@@ccrane3529 M3M or M3E? not sure if it matters?
Thank you !

Thank you for the informative video Kyle. Question, why does the altitude default to 150m? Is this because of the aster data being 30m resolution?

We did not offer terrain follow for Mavic Pro or Mavic 2 Pro.
Any chance this will become available for the new Air 3? If not, is the next best option to manually adjust waypoints based on elevation?
can you please tell me the difference between mavic 3E and Mavic 3M comparison 3D model photogrammetry
Hello!!! Where can I find a working .prj file for EPSG 4326 ? So i can export my pre-DSM so i can have an accurate terrain following?
As you mentiond flying over DSM is a very essential tools for mapping for max safety and accuracy . BUT why you dont use this option for RTH ? when the mission finish or battery finish Mavic dont return to home over DSM and it has PRESET and optimal RTH mode which both of them has some negative points and causes to decrease safety .
It would make it a lot clearer if it noted that you need to select AGL to enable terrain follow.
Looks AGL was added in a recent update.
how to apply terrain follow in linier mission?
Kyle - Where can I get technical support specific to Terra. The support phone number knew nothing about it. Thanks for the help.
We suggest working with your Enterprise Dealer or contacting us by email at support@dji.com .
Does mavic 3 enterprise work for video and photo profesional also ?
why not choose the epsg that the imported dsm is in?
That would be nice
No terrain follow after last update??
They did not, you just need to select AGL when creating a new flight map. Then it pops up.
Why is there no Real-Time Terrain follow option for the Matrice 300?

Been a long time...curious if you ever found the solution
Just upgraded the Pilot 2 and the UI is now different and no "terrain follow" is availible???? Drone is Mavic 3E.
It is bullshit
Can i trust on dsm. Which is downloaded from. Internet
Per video it is 30m resolution from satellite data so if there is not significant terrain deviations generally it works quite well though it is important to monitor the drone during flight.
Is it possible to terrain follow in a waypoint mission? I don't see the option.
Can do this in Flight Hub 2 but not currently an option in the Pilot 2 app.
Can Terrain Follow also work WITHOUT RTK?
Yes
Gibt es das Video auch auf deutsch ?
lern englisch, es ist 2023
The man says under 80m should use a DSM file, the infographic at the same time says under 30m. Which is it.
30m...used to be 80m, but in one of the later updates they dropped it down to 30m. So now it works between 30 and 200m.
