Glenn of GISuser.com has been collecting photos, maps and other graphics related to hurricanes — Katrina in particular, naturally — on his Flickr account.

Late to the party, but Microsoft has put in a solid, if buggy effort with this Virtual Earth powered feature on MSNBC’s web site. Conceptually, it’s excellent: clicking on the camera icons on the Virtual Earth hybrid map brings up before and after photos for that location, but it does not work properly in Firefox and Safari (I can’t test IE; see Cartography on bugginess). More from Chandu Thota (1, 2), Robert Scoble and the Virtual Earth team blog.

Not quite maps, but these aerial images show New Orleans beginning to dry out.
