summary
After Katrina census data become obsolete so the team adopts postal address pickup data from a donated Valassis database, builds a web app with clear metadata and maps, and uses it to answer one question: how many people are back and where. The site attracts 60,000 annual visitors before the storm and the project surfaces quality issues like 700 misgeocoded addresses and displays that break at 800x600, fixes that improve credibility; neighborhoods, volunteers and media use the maps to make real recovery choices.
