It's been lots of fun playing with Flickr the past few weeks. One of the coolest things I have discovered is Geobloggers, a site that combines Google Maps and Flickr so you can see photos taken from different map locations.

Here's how it works:

1. Tag your flickr photos with latitude and longitude data. You can use http://www.geocoder.us/ to acquire lat and lon, but I prefer using World Wind. After you find the latitude and longitude values for your picture, add the following 3 tags to your flickr photo: "geo:lat=[latitude value]", "geo:lon=[longitude value]", and "geotagged".

2. Go to Geobloggers and find your picture: Here is San Francisco, but you can change lat and lon values for other cities.

It might take a little while for geobloggers to pick up the RSS stream for your picture. To speed the process up, add a link to www.geobloggers.com in your picture description. After you log out, come back to the picture and click on the geobloggers link. If it works, you should be taken to the geobloggers google map and be able to find your picture.

Now that I've tagged a couple of photos, I am totally hooked and I want to geotag every one of my flickr photos.
