New Orleans Water Depth Post Hurricane Katrina

Investigator  Daniel P. Aldrich, FAS Weatherhead Center for International Affairs
Affiliation  Other - FAS

This project calculated average water depth by zip code zone for New Orleans right after Katrina.

Input data set was a table of LiDAR points with geographic coordinates and water depths. The technical challenge was the number of points to process - more than 26 million points for 37 zip code zones in 535 square miles.

The normal spatial statistics method would fail due to prolonged computing time. The work-around was to break the points by zones and calculate statistics per zone.
