Data Description

Saline County Ortho 2006 DOQQ Footprint (polygon)

Orthophotos combine the image characteristics of a photograph with the geometric qualities of a map. This tile is provided as a digital ortho quarter-quarter-quadrangle (DOQQQ) 1-foot ground resolution, image cast on the State Plane South coordinate system on the North American Datum of 1983 (NAD83). The geographic extent of the DOQQQ is equivalent to a quarter-quarter-quadrangle plus the over edge ranges from a minimum of 50 meters to a maximum of 300 meters beyond the extremes of the primary and secondary corner points. The over edge is included to facilitate tonal matching for mosaicing and for the placement of the NAD83 and secondary datum corner ticks. The normal orientation of data is by lines (rows) and samples (columns). Each line contains a series of pixels ordered from west to east with the order of the lines from north to south. This series of DOQQQs was produced as a part of the Arkansas Digital Orthophotography Program headed by the Arkansas State Land Information Board and the Arkansas Geographic Information Office. The aerial photography used to create the digital images was flown between December 29, 2005 and February 4, 2006
