Collaborative mapping after Katrina Hats off to two software engineers in Austin, Texas, who have developed the Katrina Information Map, a kind of collaborative map using Google to help people find out what's going on in New Orleans and along the Gulf Coast. Visitors can post tags to the map with a line or two of text describing what's been affected in a specific area.
"This map is intended for the use of people affected by Hurricane Katrina who have or are trying to find information about the status of specific locations affected by the storm and its aftermath. If you have information about the status of an area that is not yet on the map, please contribute by following the instructions below so that others may get that much needed information."
