This data depicts physical features on the surface of the earth. It has beenconstructed to be used for online access. Digital orthoimages serve a variety of purposes, from interimmaps 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 graphsand topographic maps. Orthophotos combine the image characteristics of a photograph with the geometricqualities of a map. The primary digital orthophotoquad (DOQ) is a 1-meter ground resolution, quarter-quadrangle (3.75-minutes of latitude by 3.75-minutes of longitude) image cast on the UniversalTransverse Mercator Projection (UTM) on the North American Datum of 1983 (NAD83).The geographicextent of the DOQ is equivalent to a quarter-quad plus The overedge ranges a minimum of 50 meters to amaximum of 300 meters beyond the extremes of the primary and secondary corner points. The overedgeis included to facilitate tonal matching for mosaicking and for the placement of the NAD83 and secondarydatum corner ticks. The normal orientation of data is by lines (rows) and samples (columns). Each linecontains a series of pixels ordered from west to east with the order of the lines from north to south. Thestandard, archived digital orthophoto is formatted as four ASCII header records, followed by a series of 8-bit binary image data records. The radiometric image brightness values are stored as 256 gray levelsranging from 0 to 255. The metadata provided in the digital orthophoto contain a wide range of descriptiveinformation including format source information, production instrumentation and dates, and data to assistwith displaying and georeferencing the image. The images have been projected in to the OregonGeographic Information Council (OGIC) standard projection (Oregon Lambert). A description of thecoordinate system is found at: http://gis.oregon.gov.
