-----------------------------------OLDER DATA-----------------------------------

This data was made available to Google and we have been given permission to publish it for Google Earth users. It contains the damage assessment data that was used to create this document: http://www.gismaps.fema.gov/2005pages/dr1603.shtm


NOTE:
As flooding recedes, these data should represent the maximum flooding extent at the time of update. Future data sets may show smaller flooded areas as the flooding is pumped out.

Data included are:
- flood coverage
- damaged areas, categorized by severity
- road/rail/bridge outages

This is VERY useful data for displaced residents and emergency personnel.

Note, these files make heavy use of "filled polygons". If your graphics card or driver is having problems with them (either not drawing or drawing "zingers"), try switching from OpenGL to Direct3D (or vice versa). Upgrading your graphics driver to most recent is always a good idea.

If that doesn't work, try files labeled "-float", such as:
Katrina Damage Assessment 19Sep-6pm-float KMZ file (floating polys for older graphics cards)
These avoid the use of clamped filled polygons. They may draw a bit slower but are more likely to work on old cards.
