Elements: GPS Coordinates are changed in EXIF after a 'Save Metadata to File' in Organiser

I have found that the original GPS coordinates are changed in the EXIF after a 'Save Metadata to File' for a keyword for example. 

As an example: on one image the coordinates have changed from 52 8.9373N 0 37.1740W to 52 8.9333N 0 37.1667W.

It's as if the coordinates have been truncated.

I reported this problem in version 11, 4 years ago and it has not been resolved in versions 12, 13, 14 and now version 15.

I would be extremely grateful if it could be resolved due to the fact that as it is I cannot save keywords to the metadata without corrupting the coordinates

Yes, there is a rounding/truncation when you write metadata to files.
Another instance:
My GPS Latitude is 48,50,1999664307 N
After writing metadata to files it's now:  48,50,20N
Not sure my calculations are right, but it seems that's an error of 37 meters (please correct me if I am wrong...)

So, yes again, you get corrupted values, even if the precision is probably good enough for most geotagging uses of a photo library (unless my calculation is false...)

If keeping the original values is crucial for you, I could imagine keeping the original and doing your tagging and writing metadata to files to a copy in a stack or version set.

I don't understand why Organiser rewrites the coordinates when they haven't been changed.
There is no need to.
In any case it shouldn't be changing fields in the metadata that have not been specified

I believe Lightroom has a similar problem..

I have just got Organiser 16 and found that there is a bigger bug in "Save Metadata to file" for GPS coordinates that are longitude EAST

For GPS coordinates that are longitude WEST there is still some rounding.

Organiser does set values for the four attributes in the file -  LatitudeRef , Latitude , LongitudeRef , Longitude 


For GPS coordinates that are longitude EAST

Organiser sets the  attributes in the file -  LatitudeRef , Latitude  correctly

                 LongitudeRef  is not set at all

                 Longitude is set only to the nearest degree                                                               with 0 minutes and 0 seconds

  

becomes

 

Rather more that 36 meters !!
