PE&RS November 2007

This month’s cover imagery was provided by Woolpert Inc. and comes from the Ohio Statewide Imagery Program (OSIP) being conducted for the Ohio Offi ce of Information Technology (Ohio OIT). Located in downtown Columbus near the banks of the Scioto River, the Ohio Statehouse construction began in 1839. Color digital orthophoto imagery and refl ective surface lidar data colorized by elevation portray its unique architecture. Digital imagery and lidar collections were completed in the spring of 2007 at 6” (15cm) and 6’ (2M) resolutions respectively, using the Leica ADS40 and ALS50 aerial sensor systems. Imagery and terrain products created from this statewide collection are being used in a wide variety of applications throughout the State of Ohio to support GIS, environmental monitoring, planning and engineering projects. Much of the data processing for this project was completed using the GeoCue suite of products, including GGR CuePac for ADS40 rectifi cation, LIDAR 1 CuePac for LiDAR management and processing and DEM CuePac for the preparation of elevation data for orthorectifi cation. All three CuePacs make extensive use of GeoCue’s Distributed Processing system. For information regarding the OSIP contact Woolpert Inc. at info@woolpert.com, (937) 461-5660. For information regarding GeoCue Corporation software or services contact info@geocue.com, (256) 461-8289.
