ESRI has released a mashup map of the unrest in Libya that combines information, images, and videos from geo-located posts to Twitter, YouTube and Flickr.
The default search terms return good results, but can also be tweaked to find the specific type of information that users are interested in. There is also an option to only show posts from the previous 24 hours.
Social media is playing an increasingly important role in getting information from citizens out into the world, and with most social networks now supporting geo- tagging, maps like this have become commonplace, but important, tools in broadcasting on the ground information as it happens.
