Service Description: The purpose is to provide a seamless raster image for Oregon of the 2005 half-meter orthoimagery. This data depicts physical features on the surface of the earth. It has been constructed to be used for online access. Digital orthoimages serve a variety of purposes, from interim maps to field references for earth science investigations and analysis. The imagery (or extracts from it) may be useful as a layer of a geographic information system and as a tool for revision of digital line graphs and topographic maps. A State Lambert mosaic derived from half-meter resolution color Digital Orthophoto Quadrangles (DOQ) of the entire state of Oregon from the summer of 2005 for multiple state agencies in Oregon. The original content was produced utilizing the scanned aerial film acquired during peak agriculture growing seasons under the National Agriculture Imagery Program (NAIP) under contract for the United States Department of Agriculture (USDA) for the Farm Service Agency's (FSA) Compliance Program. A DOQ is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed. A DOQ combines the image characteristics of a photograph with the geometric qualities of a map. The geographic extent of the DOQ is a full 7.5-minute map (latitude and longitude) with a nominal buffer. The horizontal accuracy is within 5 meters of reference ortho imagery (1992 USGS DOQs.) The 1992 USGS DOQ imagery met National Map Accuracy Standards at 1:24,000 scale for 7.5-minute quadrangles. Translated to the ground, the 0.5 mm error distance at 1:24,000 scale is 39.4 ft (12 meters), making the absolute accuracy for the 2005 Oregon DOQs +/- 17 meters. The process of reprojecting and mosaicing the images may have added a potential shift of +/-0.75 meters, making the cumulative accuracy +/-17.75 meters. The original images were projected into a GCS_WGS_1984_Web_Mercator(Auxiliary Sphere) for compatibility with other generic web map services.
