ESRI has published a very nice map that shows Irene’s impact as captured in Flickr photos, Youtube clips, and tweets. If you get over the clutter at lower levels of resolution, it looks like a very nice idea.
For some years ESRI has been slowly but surely pushing the envelope in terms of making GIS more web friendly. Although a slow slug, the jig is finally up. ESRI is getting where it should’ve been a long time ago.
For our own coverage of Irene in KMZ maps, see the list of related resources below. Our most visited page was the one posted a day before the hurricane, on possible flooding of Manhattan.
