unable to write gps Track angle

[ncysys]

Edit: Split from this old thread.

Hi Phil,  I tested your instructions for embedding GPS Lat, Long, Altitude and Track angle into EXIF and that works great for the first image. But subsequent images the Track angle is missing. Also my other problem is when I try to add the non standard GPSRoll and GPSPitch to the EXIF, it doesn't work. I renamed your config file to example.config to ExifTool.config to ExifTool.cfg and changed the command line accordingly. eg: 
exiftool -config ExifTool.cfg -csv=position_data.txt -gpslatituderef=N -gpslongituderef=W -gpsaltituderef=above -gpstrackref=T .

Any help would be appreciated. Thanks

What is the exact output from your command.  Also, what are the first few lines of your CSV file?  Are some of the files that don't work in subdirectories?

The command prompt output is shown here:

C:\ExifTest2>exiftool -config ExifTool.cfg -csv=position_data.txt -gpslatituderef=N -gpslongituderef=W -gpsaltituderef=above -gpstrackref=T .
    1 directories scanned
  69 image files updated

C:\ExifTest2>

This is the first few lines of the CSV file:
SourceFile,GPSLatitude,GPSLongitude,GPSAltitude,GPSRoll,GPSPitch,GPSTrack

After reading Faq #3 I corrected the filename of the .ExifTool_config filename and it did the exact same result.

I realized that the orientation values of Roll Pitch and Heading must be positive numbers. So I corrected the csv file in excel to add 360 degrees if the value was negative. This resolved the issue of missing GPSTrack values written to the Exif data.

The Last issue is the GPSRoll and GPSPitch is still not being written. I added the command print "LOADED!\n"; to the end of the .ExifTool_config and this confirmed that the .ExifTool_config file was being loaded into the application.

Why do you say they aren't being written?  To see them you must use the same config file that you used to write them.  Try using the -v2 option when writing to see what is written.

Hi Phil, I used the -v2 and the output was displayed and I copied the last file processed and saved in "Output.txt".
It looks like it does write GPS:GPSPitch and GPS:GPSRoll. When I use ExifToolGUI to display the GPS settings the results are shown on the two files "screenshotGPS.jpg and screenshotXMP.jpg"  The GPSRoll and GPSPitch doesn't show under the GPS section but under the XMP section more of the data is present. The data does write although GimbalRollDegree does not appear in the XMP drone dji section where I would like it to appear.

Here is the first row of the position_data.csv:

Code Select Expand

SourceFile,GPSLatitude,GPSLongitude,GPSAltitude,GPSRoll,GPSPitch,GPSTrack,Latitude,Longitude,AbsoluteAltitude,GimbalRowDegree,GimbalPitchDegree,GimbalYawDegree.

Thanks for looking at my problem

These are custom tags, and won't show up with the other GPS tags unless you are using the custom config file.

I'm ok with the GPS tags as they are now. The important tags are the drone-dji:Gimbal tags which do appear to be present except for the drone-dji:GimbalRowDegree which isn't present. I suspect it isn't present is because the XMP-exif:GimbalRowDegree had higher priority over the XMP-drone-dji:GimbalRowDegree. Is there any way to force XMP-drone-dji:GimbalRowDegree to be written first?

[Phil Harvey]

Sorry, I missed that you wanted to write to XMP-drone-dji.  You just need to specify that namespace in your config file.

You should be looking at the raw XMP (with exiftool -xmp -b FILE) to see what was written, and you'll need to get the URI for the drone-dji namespace from there.

Thanks I will try that.
