Hi, gang. I'm scanning in old slides and using Google Maps to derive GPS coordinates, then entering those coordinates into ExifToolGUI. However, every time I check the coordinates on a map using Jeffrey's Exif viewer (http://regex.info/exif.cgi/exif.cgi), the coordinates are showing that my pictures were taken, for example, in the middle of the South China Sea.
For example, Google Maps gives me a longitude of -123 degrees, but ETGUI won't let me enter the hyphen. I think this is the cause of my problem but I'm not sure.
What am I doing wrong?
Thanks!

Hi Greg,
If you are writing EXIF GPS information, you need to write GPSLatitudeRef (North or South) and GPSLongitudeRef (East or West) as well as GPSLatitude/GPSLongitude (which are unsigned in EXIF).

Hi, Phil. Thanks for the reply. I think I'm doing that already. That is, the GUI has a check box for North and East. I check it for North and leave it blank for East, which would (I thought) indicate West. Hmm.
Hi Greg,
You're right about "unchecked=West".. I've (again) tried with GUI:
45°00.000 +checked (=North)
123°00.000 +unchecked (=West)
50 m +checked (=Above sea level)
-and data is, according to ExifTool, saved as it should (New York area). I don't know about Jeffrey's tool...

Added: I forgot to mention, that GUI writes values only into Exif GPS section -any existing GPS data inside Xmp section isn't modified.
If this isn't working, I suspect that there may be some intereference from GPS information stored in XMP format, which requires a signed value.

Thanks, BogdanH and Phil. I'll play around with it a bit more. I'm very new to GPS, so there seems to be a bit of a learning curve.
