USDA-FSA-APFO 20060105 USDA-FSA-APFO Digital Ortho Mosaic Salt Lake City, Utah USDA_FSA_APFO Aerial Photography Field Office 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 +/- 5 meters of reference digital ortho quarter quads (DOQQS) from the National Digital Ortho Program (NDOP); and, 2 meter GSD ortho imagery rectified to within +/- 10 meters of reference DOQQs. The tiling format of NAIP imagery is based on a 3.75' x 3.75' quarter quadrangle with a 300 meter buffer on all four sides. NAIP quarter quads are rectified to the UTM coordinate system NAD83 and cast into a single predetermined UTM zone. NAIP imagery can obtain as much as 10% cloud cover per tile. This file was generated by compressing NAIP digital quarter quadrangle image tiles either natural color positive or color infrared positive source imagery into a single mosaic. The mosaic may cover all or portions of an individual county. MrSid software compression, with mosaic option, was used to create the final product. Target values for the compression ratio are (15:1) and the maximum N-levels are used. All digital products and the underlying source images were produced through the National Agriculture Imagery Program (NAIP). The primary purpose of the mosaicked digital ortho quarter quads is to support USDA Field Service Centers located in counties throughout the United States. The 1 meter GSD NAIP is intended as a source for current digital ortho imagery in USDA Field Service Center GIS and for other uses that require ortho imagery acquired during the agricultural growing season. 2005 Acquisition years of source image Dates.

No. 111 Georectified Image NAIP Digital Quarter Quadrangle used in Mosaicked County Image. Buffered DOQQs mosaicked with MrSid (MG3). The following steps apply to the mosaicking process in general. Image Tone Adjustment: The area of coverage that images are attached within are individual counties. Image tone adjustment is performed for two primary reasons: 1. To produce a well contrasted image so that users are not required to adjust the tone upon display or to create an enhancement lookup table upon delivery. 2. To reduce visible tone differences between mosaic seam lines. Methods of Image tone adjustment: Automatic Contrast Adjustment - Each input digital orthophoto quadrangle within a county is also run through an automatic tone or range adjustment that drives all input images toward a common value. The intention is to reduce vignetting and "hot spots" from the source photography, and to minimize tone differences along mosaic seam lines. Defining Mosaic Seam Lines: Automatic seam lines. Digital orthophoto quadrangles are edge matched, or seamed, across county boundaries. Mosaic Generation - Image 3.75 minute quad tiles are either generated individually and sequentially as work progresses through a project, or cut out from a larger mosaic after it is generated. Since the imagery is being resampled to the same coordinate system, nearest neighbor resampling is used. 20060105 Calvert, MD Raster Pixel 63585 33103 1.000000 1.000000 8 1 Upper Left FALSE LZ77 3 pixel codes FGDBR TRUE row and column 1 1 meters North American Datum of 1983 Geodetic Reference System 80 6378137 298.257 24-bit pixels, 3 band color(RGB) values 0 - 255 None ortho_1-1_1n_s_md009_2005_1.sid.vat Table 256 OID OID OID 4 0 0 Internal feature number.
