Abstract:
"This data is standard [filmtype] 1-meter resolution orthoimagery that is equivalent in many characteristics to U.S. Geological Survey Digital Orthophoto Quarter-quadrangles (DOQQs). A DOQQ is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed. A DOQQ combines the image characteristics of a photograph with the geometric qualities of a map. The geographic extent of the DOQQ is equivalent to a quarter of a 7.5-minute map (3.75 minutes of latitude and longitude) with overedge. The overedge ranges from a minimum of 50 meters to 330 meters beyond the extremes of the quarter-quad area. The DOQQs were produced with a 1-meter ground sample distance (GSD) and are cast on the Universal Transverse Mercator (UTM) projection on the North American Datum of 1983 (NAD83). The DOQQ were produced to meet a National Map Accuracy Standard (NMAS) for 1:12000 scale maps (10.16 meters radial error at a 90% probability). The DOQQs are three band natural color images in TIFF format with associated .tfw world files for georeferencing purposes. The source photography are at a nominal scale of 1:40,000 (flown approximately 20,000 feet above ground). Most of the orthos were created from a single source image for each DOQQ but some were produced from mulitple images to minimize perspective related image smearing problems. This set of DOQQs covers 12 of the 15 Arizona counties. The three counties not included are Cochise, Maricopa, and Pima."
Purpose:
"This data depicts geographic features on the surface of the earth. DOQQs serve a variety of purposes, from interim base maps to field references for earth science investigations and analysis. The DOQQ is useful as a layer in a geographic information system (GIS) and as a tool for performing digital map revision."

Attribute_Accuracy:
Attribute_Accuracy_Report:
"Scanning was done from the film positives. Image brightness values may deviate from the original images because of image value interpolation during scanning and rectification processes. Radiometry is verified by visual inspection of the digital orthophoto. Some systematic radiometric differences exist between adjacent orthoimage files; these are due primarily to differences in source image capture dates and sun angles along flight lines. These differences can be observed in an image's general lightness or darkness when it is compared to adjacent orthoimage file coverages."
Logical_Consistency_Report:
"All digital orthos for this project were validated using ESRI ArcMap software to ensure correct naming, image location and the relative horizontal fit of adjacent images. Images were also inspected for other characteristics such as perspective related image smearing, alignment of transportation features, and relative fit to earlier vintages of similar digital orthos produced by the U.S. Geological Survey."
Completeness_Report:
"All digital orthos for this project were inspected for completeness to ensure that there were no gaps in coverage."

Source_Contribution:
Airborne GPS and IMU data positioning were computed by MDA Geospatial Services and used as control in the aerotriangulation process. ABGPS/IMU positioning was based on base stations at each of the airports used for acquisition. Observations were in WGS84.
Process_Step:
Process_Description:
"Color positive film was scanned using Z/I PhotoScan photogrammetric quality scanning machines at a resolution of 21 microns. The scanned digital imagery and ABGPS/IMU data was used in the Aerial Triangulation (AT) process to provide final georeferencing and image orientations in preparation for orthorectification. Orthorectification was done using Z/I Base Rectifier with Cubic Convolution Interpolation. Each DOQQ was then inspected for relative horizontal accuracy with adjacent DOQQ tiles. If there were features that had excessive misalignment between adjoining DOQQs then the USGS DEM was locally updated using a Z/I SSK softcopy work station. Each DOQQ was inspected for image quality, smears, and artefacts such as hairs or annotation. Such image defects were fixed in Photoshop or corrected by mosaicking imagery from an adjacent frame with a better "look angle". This was particularly challenging in the Grand Canyon complex. DOQQs were color and radiometrically balanced over large blocks using internally developed image manipulation software."
