WTI is conducting CART surveys around the former World Trade Center (WTC) in New York City. The 3D radar images are used as one of the means to reconcile utility maps, to help reduce the number of testpits dug, to assist in finding clear lanes and ultimately to help rebuild the infrastructure faster.

As of February 13, 2002 WTI aurveyed 25 days (nights) for a total area of about 300,000 sq-ft. Before September 11, 2001 55,000 sq. ft were surveyed for ConEdison. Since then an additional 250,000 sq-ft was surveyed. The total covered area around the WTC area is shown in the map below as of February 28th, 2002.
