I was playing with the latest version of Picasa and Google Earth tonight. The “really cool feature from google”TM that I was trying to figure out is image geotagging. Basically Geotaggin is labeling a photo so you can place it on a map. See Wikipedia, Geotagging.
The whole process is to select a photo in Picasa, choose the geocoding option in some obscure, buried menu, and find where you took the photo in Google Earth. I then created a Google Earth file that allows you to view the images from within Google Earth. Way Cool!
I also exported a web photo album to my webserver. I tweaked the caption to include a link to the file.
It’s all a work in process, so if the links to the stuff I am talking about today are gone next week, look around, they probably found a better long-term home.
