New Orleans Water Depth Post Hurricane Katrina

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