Lightroom: Copy Metadata loses GPS precision

The Metadata > Copy Metadata command truncates the precision of the copied GPS location. For example, Exiftool reports the location of the source photo as:49 deg 8' 0.61" N, 114 deg 1' 33.62" WBut after copying it with Copy Metadata, Exiftool reports the location of the destination photo as:49 deg 8' 1.00" N, 114 deg 1' 34.00" W So not only does LR round coordinates for display in the metadata panel, it also rounds when copying coordinates. See this related topic for details about the display problem:http://feedback.photoshop.com/photoshop_family/topics/preserve_precision_of_gps_coordinates_entered_...

(Last tested in LR 7.0.1.)

Wow. This is bad.

And I thought it was bad that older versions of ExifTool rounded to the nearest 0.01 seconds when copying GPS information. But ExifTool was fixed 5 years ago, and now maintains 8 decimal points of precision for GPS seconds.

A typical GPS receiver is now accurate to a few metres, which is 0.1 seconds, and some people require centimetre accuracy, which is better than 0.001 seconds.

Rounding to the nearest integral second as LR does is absolutely unacceptable.

This bug still exists in LR 6.0.1 / OS X 10.10.3.
