Question

GPS location imported from iPhone has wrong hemisphere

In LR Classic 9.1, the Map module has the wrong hemisphere (E versus W) for the GPS location. So instead of showing the location as northern California, it shows it in China.

 

I exported iPhone photos from the Photos app on a Mac (export unmodified original; checked Export IPTC as XMP). When I look at the file itself in Preview, it shows the following (correct) coordinates (northern California):

 

Latitude: 40° 26’ 32.508” N
Longitude: 123° 59’ 20.04” W

 

 

I imported the photo into Lightroom, and it shows the following GPS coordinates (China).

 

40°26'32.508" 123°59'20.039"

 

If I manually add N and W to the GPS coordinates, then it shows the correct location.

 

I don't know what to do to correct this before I start editing/modifying thousands of photos!

SOLVED (I think).

I tried several experiments. (note: The files are in the native .HEIC file format, and the names for experiments 1 and 2 were the default iPhone file names)

(1) I exporting from the Photos App again, imported into Lightroom along with the associated XMP file (which I realize has the full GPS info in much more detail than I was reporting) and replicated the problem: The Map shows the location as China, having dropped the N and W hemisphere identifiers.

(2) I imported into Lightroom, but this time I deleted the XMP file first. The GPS location is correct! It has the N and W identifiers!

(3) I ran the files (both the .HEIC and the .XMP files) through ExifRenamer to change the file names. Now the GPS location is, again, correct! (The .xmp files in approaches 1 and 3 appear to be the same, when I visually inspect them.) 

 

I don't understand the inconsistency in reading GPS hemisphere information, but at least it works some of the time.
