TxDOT 17 County Orthophotography Project

One of the World's Largest Aerial Mapping Projects
Between January 2007 and December 2007, a professional mapping services and GIS team headed by Bohannan Huston, Inc., (BHI) completed one of the largest orthophotography projects ever attempted in the United States. BHI, a leading engineering, spatial data, and advanced technologies firm, led the challenging 11-month aerial photography project that covered more than 13,715 square miles in north central Texas. Extraordinary efforts by the entire project team―including 3001, Inc.; Photo Science; Lina T. Ramey & Associates; and PRO-TERRA Aerial Mapping, Inc.―produced a project that was completed on time, within budget, and with outstanding quality. The success of the project demonstrates how the photogrammetry discipline has grown through the advancement of key technologies, and how innovative approaches by BHI are enabling this progress.
