Hello.

In the P2V+, shooting photos in interval mode, sometimes the GPS coordinates recorded in the EXIF of photos seems to be the location the Phantom took off, and not the location of the Phantom when it took the photo. Has anybody else noticed that?

Daryl.

No, I had not notice that.  In fact, I did not know that the photo data contained the GPS coordinates at all because I read someone's statement on this forum, or another, that it did not.

Now that I've actually looked myself, it sure does.  Cool.

Thanks,

Jamie

From this morning's flight (see the image thumbnails below) I can see consecutive images where one image has the coordinates for the take-off point (e.g. DJI00357 and DJI00359), and the other image has the coordinates for the Phantom's current position (e.g. DJI00358). I've seen it happen often enough, and randomly enough, to suggest it might be a bug. At this point it seems the coordinates in the EXIF are fairly unreliable and therefore pretty much useless. Is there a way of raising issues with DJI for investigation?

I discovered the same problem when I was trying to import the embedded GPS information in a 3D mapping program.  Got really wacky and totally useless output from the program.

I also have a problem with the altitude reported. I have several pictures taken during ascending, different heights ad they all show the same altitude EXIF data

That's very interesting...
According to your coordinates you were flying near the Woodend & Distric Netball Club (Buffalo Stadium)  in VIC, is that correct?
(Adelaide here)

I've compared the exif data from a Phantom 3 Professional with photogrammetric resections of the GNSS position with a standard deviation of about a metre in horizontal position. The vertical position appears to be relative to the take-off point. I've only done this for a small block of eight photographs and would be interested if anyone else has obtained similar results.

I'd also like to know if there is anything like the exif GPSImgDirection tag stored in the DNG file (that's kappa to photogrammetrists).
