Summary

• Despite numerous written and verbal requests by
  multiple Parish contacts, a uniform, useful and
  complete imagery coverage of the Parish was
  difficult to obtain.
• Much of the data that has been provided has been
  delivered in formats that are not conducive to
  quick and easy integration into existing GIS
  structure.
• Agencies have been unable to deliver post Katrina
  coverage of all damaged areas (entire Parish)
  even before Ritas effects were felt.
• Continued

39
Summary (continued)

• Agencies have delivered other images (video and
  still obliques) but these have little value for
  GIS analysis.
• The importance of receiving complete post-Katrina
  imagery is of extreme importance, especially in
  regard to assessment of damaged properties and
  infrastructure due to a particular storm.
• High turnover rate of FEMA, National Guard etc.
  support means multiple requests must be made to
  get the message through.
