Mavic 2 support

Can I assume the Mavic 2 Zoom will be supported as well?

Thanks

The Mavic 2 Zoom will be supported in the next release. 

Any update/timeframe as to when the Mavic 2 Pro will be supported?

Any updates on the release of the Mavic 2 Pro support date?

There are still some issues with the DJI SDK we are trying to work through before it will be made available. All of the new versions of the Mavic 2 series will be supported.

For planning purposes:

Mavic 2 Zoom at 24mm - 60 meters, 2.1 cm/px, Max flight speed 6.2 m/s

Mavic 2 Zoom at 36mm - 60 meters, 1.5 cm/px, Max flight speed 4.4 m/s

Mavic 2 Zoom at 48mm - 60 meters, 1.1 cm/px, Max flight speed 2.2 m/s

Mavic 2 Pro - 60 meters, 1.4 cm/px, Max flight speed 5.1 m/s

Phantom 4 Pro - 60 meters, 1.6 cm/px, Max flight speed 6.0 m/s

Mavic Pro at 24mm - 60 meters, 2.0 cm/px, Max flight speed 5.8 m/s

Support for the Mavic 2 Zoom and Mavic 2 Pro has been released in version 2.9.2.

I just conducted two mapping missions with my Mavic 2 Pro. The first mission lost several photos. Signal strength was reported as 100% the entire flight, however the log file shows several data drop outs. The second mission I few using connectionless mode. That seemed to work much better.

My guess, the M2P's SDR radios aren't prime time, especially if you need prefect connectivity to snap the shutter. I was at most 400 meters away, line of sight, with no obstructions. Drone was flying at 100 meters.

I can verify that I had the same issues as Steven Wallace.  Random photo collection unless in connectionless mode.  I did two missions at 400ft. with clear view of Mavic 2 Pro the entire flight.

You guys really got out there early! The latest version has only been out for a few hours.

It almost always seems like their are radio signal issues with early use of any new aircraft. Keep an eye out for firmware updates. This isn't something we can fix but will keep an eye on it.

Also just noticed the altidtude of the imagery collected during the same mission is wildly variable. 

I would be happy to share any images if they can help this diagnosis in any way.

That doesn't sound good... Please email the affected log file or post the images to Maps Made Easy for processing and let us know which job it is so we can see what is going on.

The M2P has a bug WRT GPS altitude. It's stuck at "115544442 m Above Sea Level". Depending on your photogrammetry tool, you have to correct based on relative altitude.

@Zane

I have uploaded 73 images below are the project details.  Please let me know if you need anything else.

FYI, the M2P appears to have a more stable barometer (compared to the P4P). It also appears to have more consistent GPS location information in the images (again, compared to the P4P). My guess is that there's less delay, or more consistent delay, between recording the GPS location and capturing the photo, especially in connectionless mode.

FYI, my missing photos correlated with the following:

Photo Error: Error Domain=DJISDKCameraErrorDomain Code=-3002 "Camera is busy or the command is not supported in the camera's current state(code:-3002)" UserInfo={NSLocalizedDescription=Camera is busy or the command is not supported in the camera's current state(code:-3002)}

The drone was flying pretty fast 9.9m/s. I was using a SanDisk Extreme Pro V30 SD card.

A "Camera Busy" error means you have the SD card write speed set to be too fast in the Settings. The Mavic 2 Pro may be slower to write frames than the P4P so you may need to turn it down. Smaller/Cheaper aircraft usually means less capable hardware so it wouldn't be surprising that it can't handle fast framing like 2 sec/image or even 2.5 sec/image. Try setting it to 3 sec/image to see if that error goes away.

We are seeing the weird GPS altitude tags too. We have made the required adjustments in Maps Made Easy to deal use the relative elevation tags if a ground reference image is supplied (just like with any other DJI camera).

@Zane

Have all of these issues been addressed in a new release?  What version?

Thanks

Mavic 2 Pro and Zoom support has been officially added but there are still firmware issues that are affecting the accuracy of the exif geotags. This is not something we can fix. Hopefully DJI will address it in a firmware update soon.

Hello Zane,

Shall I assume that you have empirically tested the DJI Mavic 2 pro and DJI Mavic 2 zoom to derive the statements:

Mavic 2 Zoom at 24mm - 60 meters, 2.1 cm/px, Max flight speed 6.2 m/s

Mavic 2 Zoom at 36mm - 60 meters, 1.5 cm/px, Max flight speed 4.4 m/s

Mavic 2 Zoom at 48mm - 60 meters, 1.1 cm/px, Max flight speed 2.2 m/s

Mavic 2 Pro - 60 meters, 1.4 cm/px, Max flight speed 5.1 m/s

If you did test the drones, did you also tested how repeatable is the Mavic 2 zoom focal length is?

The reason I'm asking this question is because I event though the camera focal length has been specified through Map Pilot app I fear small readjustments of the focal length each time the battery of the Mavic 2 zoom is swapped for a fresh one leading to photogrammetric flights with slightly different focal lengths on consecutive batteries occurring each time the drone is powered up after each battery change.

By the way, do you have input from DJI support team on when they will fix the weird altitudes tags on the pictures?

Thanks

Isaac

Isaac: These numbers are calculated numbers based on focal lengths, overlaps and altitudes. The focal lengths should be pretty good since that is handled directly by the DJI SDK and the internals of the camera. We don't have enough good data on this yet due to the tagging issues. 

Feel free to reach out to DJI to let them know this firmware issue is causing large issues for you. They know about it and I would hope an update would be coming out soon.

Helo Zane,

I started a forum thread with DJI.

Thanks

Isaac

Hi Zane,

Someone in DJI forum said: "Fixed in FW v01.00.01.00" (release date from yesterday) but if I check the changelog at https://forum.dji.com/thread-169070-1-1.html doesnt say anything on image tags.

I don't have a Mavic 2 to test this out, has really been ironed?

Thanks

Isaac

There have been image tag issues before and they didn't spell it out then either... We will test it and verify soon.

We ran a couple of test jobs and are not seeing that the latest firmware has fixed things. They changed, but they are not fixed.

Hello Zane,

Any chance to get a picture out of your testing so that I can go back to DJI?

Again, I don't (yet) have a Mavic 2 drone to take my own pictures.

Thanks

Isaac

Here is what we have figured out on the Mavic Air and Mavic 2 tags so far:

11/27/2018
I updated my Mavic 2 Pro to the newest firmware 

• Date: 2018.11.22
• Aircraft Firmware: v01.00.02.00

I did a small mapping mission on Saturday Nov 24th and the map actually rendered on the correct location in the output on Google Earth.
My previous attempts with the older firmwares resulted in fragmented maps scattered randomly about on Google Maps overlay which were unusable.
The previous issues were a result of incorrect GeoTag data.
Has anyone else tested the latest firmware to confirm the GeoTags are now correct?
