I haven't tried it yet, but the new Mac OS 10.4.9 update fixes a problem in Aperture:
GPS metadata is preserved when image versions are exported.
And there was much rejoicing... Yay!
This is actually a really common problem with most photo-editing programs. You're lucky if they retain much, if any, of the EXIF metadata for an image. All that time spent putting in Copyright, Headline, Caption, Location, Subject, etc. is usually probably lost the minute you export to JPG or upload to Flickr. It's nice to see applications, especially professional-grade ones, supporting the additional metadata.
The Update addresses another issue I ran into the other day:
Addresses an issue in which incorrect encoding could be used for the files created by the â€œNew Text Fileâ€ Automator action on Intel-based Macs.
I was trying to setup Automator actions for my Pertelian X2040 LCD in an upcoming MacTech Magazine article. Now I can add lines for upcoming iCal events, Mail messages, and perhaps even pipe these out to my NabazTag!
