Caveats and Addendums

• Clearly it would have been beneficial to have access to additional data regarding the Hurricane, but when Katrina hit and then Rita, gathering data is most likely not at all a priority

• Regardless of missing attributes, this is still an important area of study

• Groundbreaking in terms of being able to see new applications of GIS for other disasters, using Google Earth/Twitter/Social Networking to track disasters, Hurricane Sandy Shapefiles are already available

• Problems:• Many clearinghouses, databases, including FEMA have

been closed or have severely limited access only allowed to organizations associated with rebuilding or giving grants

• Disaster data is by nature very unreliable, due to the constant changes in population, displaced citizens addresses etc
