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.
