ANOTHER VIEW: Missing data at the center of the storm

By Pari Sabety & Josh Knauer, Special to GCN

The quiet crisis at the center of the chaos following the natural disasters in the United States in 2005 was a total breakdown of already inadequate local data and information systems. With an army of public and private sector volunteers converging with relief supplies, good information and its real-time exchange were the items in shortest supply. This was especially true in the aftermath of Katrina. Before the system is tested again, it is imperative that we address this critical need.

Accurate, available, accessible and detailed local neighborhood information is critical to coordinating rescue operations, assuring safety and targeting investments to those in the greatest need. Data like this wasn’t available for New Orleans or parts of Florida affected by Wilma, let alone most urban areas in the United States that could be affected by a hurricane, earthquake, terrorist attack or other disaster in the future.

This information shortage doesn’t just impact voluntary efforts; it is also impeding the efforts of troops brought in to assist in ongoing hurricane relief (relief that will continue for many months to come). In Iraq, the Army’s 1st Cavalry Division was called in to respond to immediate danger, eliminate floodwaters, provide clean water, restore sewage service, and deal with solid waste and trash. They are using advanced data visualization software deployed today in Iraq. Conceived at MAYA Design Inc., a research lab in Pittsburgh, the technology uses an “information commons” approach that enables data from thousands of sources to be combined fluidly and made available for battlefield decision-making.

But here in the U.S., they have had huge difficulties finding accurate, detailed neighborhood data in New Orleans and other areas. How can this be?

The most detailed business establishment data with accurate latitude and longitude attributes is in private hands. Data on the owners of land parcels, homes and businesses in New Orleans available online prior to the hurricane through the New Orleans Geographic Information System went offline in the flood. The standards and geographic units used to identify businesses, toxic-waste sites, schools and other important elements of a neighborhood’s physical environment differ.
