So I had a play - and I have to say that this has been quite a revelation to me because the end result are images (Canon RAW images as well JPEG) that are tagged with GPS data that allows me to bring up a map to see exactly where the photo was taken. What's more - I've added to the gallery mechanism to allow anyone tagging their images with GPS data to do the same. An example image can be seen at http://www.ukbutterflies.co.uk/phpBB2/g ... 2#comments (just expand the EXIF data and you'll see what I mean). I've added a link to Google Maps so that you can see, within 5 metres, where the photo was taken. Just imagine how useful this could be when going abroad when you don't really know where you are!
So - an explanation of the mechanics.
1. Set you camera so that it has the correct data and time, since this information is included in your images by default and will be used to correlate with the GPS information of where you were.
2. Turn on the GPS device and go out and take some photos.
3. Using appropriate software (I use a free program called "GeoSetter") tag your images with the GPS data (which it does by matching the time in the camera with the time from the GPS satellites).
4. Post your image on UKB

That's pretty much it. Absolutely amazing and I can't see me ever going out without my GPS device from now on!
I'd be especially interested in anyone else using a GPS device, because I'd like to test the UKB mechanism I've added in!
Cheers,
