Witten Technologies Inc. (WTI) was founded in 1994 by Robert Green, a 2nd-generation utility contractor, and professors Alan Witten and Tony Devaney (currently at Northeastern University), world-renowned geophysicists.

In May 2000, WTI took over the GPiR (Ground-Penetrating imaging Radar) project, a two-year collaboration with Schlumberger and utility companies around the world to adapt advanced imaging and visualization software using in petrochemical exploration to utility mapping. The GPiR project was coordinated and jointly funded by EPRI (Electric Power Research Institute) and GTI (Gas Technology Institute).

The commercialization of the GPiR project continued and since then the individual research components have been integrated to form the CART Imaging System ("CART" stands for "Computer Assisted Radar Tomography"). The CART system has been proven over the past five years, performing surveys in major cities both in the US and abroad (Please browse our projects area). Today WTI offers geophysical mapping services using the CART system. Over the past five years WTI has surveyed and interpreted over 14 million square feet of radar data.

In October 2003 WTI started to work on complementing the CART system with an electromagnetic induction array system called the AIR (Array of Inductive Receivers) system. This Dual Array Project was sponsored by the US DOT and Con Edison and completed successfully in January 2005.

Most recently, WTI, through licensee Craig A. Smith/MPS3D, performed the largest CART survey to date, scanning nearly 2 million square feet for a Florida Department of Transportation road-widening project. FDOT is currently creating standards for CART application statewide.
