On Monday, Data.gov launched a disaster-specific open data portal.  This was an initiative first announced in at the White House Innovation for Disaster Response and Recovery Demo Day this past July.  Many other innovative apps, tools and initiatives were also demoed that day.  

The portal features a number apps, tools, and data relevant to disaster and is conceptually similar to what NYC did a couple years ago with its public safety data.  In total, 114 Federal data sets are already indexed in the portal
