Google Picasa now offers you the ability to match your photos to a specific location using Google Earth. The “Geotag” feature allows you to embed location information within your photo file as well as display your photo on a satellite map rendered by Google Earth. To Geotag a photo, please follow these steps:

• Select your photo in Picasa
• Select “Geotag with Google Earth” from the “Tools”> “Geotag” menu to launch Google Earth. A small Picasa window will appear in Earth’s lower-right corner displaying thumbnails of the pictures you selected.
• Use the arrows to advance through multiple pictures. If “place taken” information has already been entered in Picasa’s folder description, Earth will automatically go to the specified locale. Otherwise, you can navigate to the location using the yellow cross-hairs which appear in Earth.
• Find the location you want, and press the “Geotag” button.
• When all of your pictures are tagged, press the “Done” button to add the information to Earth’s “My Picasa Pictures” collection. You can also use the “Geotag All” button to tag all of the selected pictures with the same location information.

Picasa will write the longitude, and latitude to the photo’s EXIF GPS metadata. For example, if you look at the “Image Properties” in Picasa you will see something like: GPS Latitude 34 1’13.04”N. Picasa will display a small cross-hair icon on the thumbnail of a photo that has been Geotagged. To remove a Geotag select “Clear Geo-tag info” from the “Tools”> “Geotag” menu. Please note that this action will remove the longitude and latitude information from the photo’s EXIF GPS metadata. This will also remove the photo from Google Earth.
