See your photos on the map! PhotoPin is an application to automatically gps-tag photos taken with any external camera. It's meant to be used with a FREE Mac desktop companion application that can be downloaded from http://www.photopinapp.com .

It works like this:

1) You launch the iPhone application and leave it running in your pocket. You pull out the camera and walk around making photos.
2) The iPhone application records time and gps position information. It automatically syncs over wifi network to your Mac when you're back home.
3) You load photos from the external camera into the PhotoPin desktop app. It automatically matches them and applies precise geo-positioning metadata recorded earlier.

Photos geo-tagged with PhotoPin work great with any application and service that understands standard EXIF jpeg tags. Any camera that records date & time will work fine with PhotoPin.

Note: PhotoPin iPhone application is meant to be used in conjunction with the FREE Mac application that can be downloaded from http://www.photopinapp.com . Other operating systems are not supported at the moment - Mac is required to fully benefit from this application.
