This six inch pixel resolution color aerial photography was flown between July 1, 2008 and August 31, 2008. The files are provided in JPEG2000, an open format supported by most GIS and CAD software packages. Its intended usage for viewing is 1" = 100. The photography has been orthorectified to meet National Map Accuracy Standards for its capture scale. The images are georeferenced to the Illinois State Plane, Eastern Zone, using the NAD83 NSRS2007 horizontal datum. The data set is tiled for dissemination into many separate tiles, each of which is 2500 feet on a side.
