Exhibit features maps and geospatial imagery created as part of the rescue and recovery effort following the World Trade Center attacks.

Several Colorado public safety officials gathered yesterday in Denver to view and discuss an educational exhibit that shares an important perspective on recovering from the events of September 11. “Charting Ground Zero – Before and After” features maps and geospatial imagery that were created following the World Trade Center attacks as part of the rescue and recovery effort. The technology used to create these images continues to be used today by local, state and federal agencies to assess damage, monitor the progress of recovery, and safely deploy personnel and equipment in the disaster zone.

The imagery represents a convergence of technologies that will have far-reaching effects on how our country can respond to attacks, natural disasters and other emergencies in the future.

"The exhibition is meant to familiarize people with the technological advancements and share with them how these advancements can benefit us all,” said Dr. Sean Ahearn, associate professor at Hunter College and director of the Center for Analysis and Research of Spatial Information Lab.

Dr. Ahearn played an important role in creating the emergency mapping center that supported agencies responding to the attacks. Dr. Ahearn also created the original exhibit in partnership with the City of New York and the Woodward Gallery.

The exhibition includes operational maps created for New York City’s Office of Emergency Management, as well as aerial imagery, laser ranging images and other images from the site. It will be on view to the public from May 23 – 29, weekdays 10 a.m. to 8 p.m. Saturday hours, 12 p.m. to 4 p.m. (closed Sunday and Memorial Day) at the Denver Police Protection Association Events Center, 2105 Decatur Street, Denver, Colorado.

This event is being brought to Denver as the result of a collaboration of the public and private sectors. Public Sector Sponsors include the City of Aurora, City of Denver and the Denver Police Protection Association. Corporate Sponsors include GE Network Solutions, LinksPoint, IBM, and Sanborn Colorado.
