Add-on:Hurricane Katrina Damage estimates

This layer is a good way to view some of the damaged areas when used in conjunction with the NOAA Hurricane Photography addon or the Katrina NOAA/USACE aerial photo addon. This add-on was created from the NGA's damage assessment of the Gulf region.

The following classes/layers are displayed in the add-on:


 * Catastrophic
 * Most solid and all light or mobile structures destroyed.


 * Extensive
 * Some solid structures are destroyed; most sustain exterior and interior damage (e.g., roofs missing, interior walls exposed); most mobile homes and light structures are destroyed.


 * Moderate
 * Solid structures sustain exterior damage (e.g., missing roofs or roof segments); some mobile homes and light structures are destroyed, many are damaged or displaced.


 * Limited
 * Generally superficial damage to solid structures (e.g., loss of tiles or roof shingles); some mobile homes and light structures are damaged or displaced.


 * Flood


 * Saturation


 * Impassable Roads


 * Impassable Rails


 * Impassable Bridges

The data was interpreted on 9/8 for the bridges, rails, roads, and 9/10 for the rest.
