General / Re: Workflow to process the Photography of "PHANTOM 4 RTK"

Hello Tim,

If you have the CSV file with the coordinates and accuracy information for them, you can import these values to Metashape Pro via Import CSV dialog - it would overwrite (in the project) the values derived from the image EXIF.
Hi Alexey, I want to be upfront here.  I currently use a different processing platform but there seemed to be cross platform issues relating to the Image EXIF data.  So that is why I posted here as this particular thread had more activity concerning the P4P RTK EXIF data than any other thread.  The software package that I use does not accept the Accuracy data without the user providing the phi, omega, and kappa values :(

maybe you need this program

Hi Alex,  Thanks for the link.  I already have a PPK solution for my Phantom 4 Pro, my only issue is updating the Image EXIF XMP data from a CSV file (which contains the PPK data).  It can be done.  I just have to figure out how.  The ExifTool program by Paul Harvey will most likely take care of it.  I will have to learn how to do it from the command line which is not my specialty.

I found this thread and hoping you guys can help.  The new P4 Pro RTK adds the following tags to the metadata.
(With sample data from an RTK photo)

Rtk Flag                        : 16
Rtk Std Lon                     : 2.70368
Rtk Std Lat                     : 1.53912
Rtk Std Hgt                     : 3.68277

I have an external Emlid Reach M+ GPS on my regular phantom 4 Pro.  I am post processing the flight data and events in EZsurv.  I export the data shown above for all images into a CSV file and  I need to import that into the metadata of the images.   Then they will be processed just like the P4P RTK images.

My problem has been finding an EXIF editor that I can figure out to import these XMP tags into the images.  My CSV file will contain

Image File name
Post Processed Lat
Post Processed Lon
Post Processed Alt

Lat Standard Deviation
Lon Standard Deviation
Alt Standard Deviation

For the updated GPS data, I will simply overwrite the coordinates currently in the EXIF data.  Then I need to add the new XMP tag data for the Standard Deviation.

Any help on the best program to use and how to do it will be appreciated.  I have played around with multiple exif editors and so far I have not found one where I can successfully add the custom data.   

Thanks again for any help you can provide.
Tim
