Kentucky 2004 NAIP OrthoImagery Tiled by KY Single Zone 20K grid Natural Color, MrSid Compressed Projection: KY SP (1 Zone), NAD 83, Feet Grid Resolution: 3.333 Feet General Description: This data set contains imagery from the National Agricultural Imagery Program (NAIP). NAIP acquires digital ortho imagery during the agricultural growing seasons in the continental U.S.. A primary goal of the NAIP program is to enable availabilty of ortho imagery within a year of acquisition. NAIP provides two main products: 1 meter ground sample distance (GSD) ortho imagery rectified to a horizontal accuracy of within +/- 3 meters of reference digital ortho quarter quads (DOQQS) from the National Digital Ortho Program (NDOP); and, 2 meter GSD ortho imagery rectified to within +/- 20 meters of reference DOQQs. The tiling format of the original FSA NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 360 meter buffer on all four sides. NAIP quarter quads are rectified to the UTM coordinate system NAD83. NAIP imagery can obtain as much as 10% cloud cover per tile. The tiling scheme for the final Kentucky EPPC-OIS-GIS dataset is 20,000 ft x 20,000 ft grid blocks rectified to the Kentucky Single Zone SPCS, US Survey Foot. Purpose: This imagery is intended as a source for current digital ortho imagery in GIS and other uses that require ortho imagery acquired during the agricultural growing season. Supplemental_Information: This statewide imagery was originally produced by the USDA-FSA Aerial Photography Field Office and published with 1-meter pixel resolution, NAD83 UTM Zones 16 and 17 Meters, in 3.75 min quarter quad (QQ) tiles. The imagery was reprocessed to 3.33333333 USFt pixel size, projected to NAD83 Kentucky Single Zone SPCS (KY1Z) USFt, in 20,000 ft x 20,000 ft (20K)blocks. |
