This imagery 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. This data depicts physical features on the surface of the earth. It has been constructed to be used for online access. It may serve a variety of purposes, including but not limited to interim base maps, ground condition references and general planning purposes and analysis. It (or extracts from it) may be useful as a layer in a geographic information system (GIS) and as a tool for performing digital map revision. 2005-06-29 2005-08-15 2005 Complete Irregular -124.997 -116.1995 46.6163 41.3701 None None. However, users should be aware that temporal changes may have occurred since this data set was collected and that some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. ER Mapper Mailing and physical address:
