We already told you that Bing maps published new imagery for Haiti after the earthquake. But what about the imagery from before?

Well, they haven’t been put to waste, they got put in a new map app!

Now you can compare before and after images, and yes that does make the devastation even more clear!
 
But that’s not all, there’s also a link to the Twitter Maps application focused on Haiti, so you can see tweets from people in Haiti. Also provided is a link to how you can help out (US links).
