.SRT data comparison

[VintageSlots]

Below are two screen captures. One shows the data from a Mavic 2 Zoom, the other is from a Mavic Pro.

The Zoom has no GPS data.

This makes it unusable for some of my jobs.

Thanks for the heads up DJI!

This is discussed elsewhere - it seems theres a SRT subdirectory containing the file now instead of directly embedded.

FWIW on stills at least, absolute altitude is out by roughly 72,000 miles.

They did remove the GPS data. You'll have to rely on flight logs if you really need it, but the fact that it's no longer accessible via SRT files is a drawback for me too.

I have already reported the issue of the altitude being halfway to the moon.

Replying on flight logs is not an acceptable solution.

Hi @VintageSlots , Could you try with the latest firmware? Apparently someone is getting GPS locations now Understanding SRT file data

If that's the case, would you mind sharing an SRT file with me? (privately if you want) I'm trying to make sure my SRT reading web-app works well: DJI SRT Flight Data Viewer

Appreciated

Wow, that was great timing. Weather has been too cold to fly much. I reluctantly updated the M2Z a week or so ago.

Weather wasn't bad today so I decided to go to RC field just to fart around and practice my off the deck flying (i.e., close to ground).

Anyway, I read the above email while at the field. I shot a short video and confirmed Long./Lat. is now in the SRT file. Here is a screen shot.

I would be happy to email it to you if you want it. This forum won't allow .SRT files to be uploaded.

Great news!

You've got more different fields than the guy at DJI's forum, but still nothing that looks like altitude to me.

I sent you my email in a private message.

Ok, I can confirm the data can be read through DJI SRT Flight Data Viewer

Still some work to do regarding time, speeds and new values (ct could be colour temperature).

As suspected, altitude is missing, but latitude and longitude are much more accurate than they are on the Mavic 1 Pro and frequency is much higher too (1 data packet per frame, instead of one each second). So some tradeoffs, some improvements, but finally some usable data .

Looks like DJI quality control is still in place. They didn't spell longitude correctly, not a huge deal, but more evidence they really don't check their work that closely.

I will need to edit the .SRT file when I deliver to customer so they don't think I am the idiot who doesn't know how to spell.

The latest Mavic2 firmware update has improved the SRT logs. Altitude is now included.
