U.S. National Park Service, NRPC, NR-GIS 20090721 remote-sensing image Fort Collins, CO U.S. National Park Service, NRPC, NR-GIS http://www1.usgs.gov/vip/foun/founortho.zip https://irma.nps.gov/App/Reference/Search doi:10.5066/F7FN1441 A Digital Orthophoto Quarter-Quadrangle (DOQQ) is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed. An orthophoto 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 300 meters to a maximum of 600 meters beyond the extremes of the NAD83 datum 3.75-minute latitude and longitude boundaries. DOQQs are 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). Each DOQQ is produced to meet a National Map Accuracy Standard (NMAS) for 1:12000 scale maps (10.16 meters radial error at a 90% probability). The 2005 DOQQs were derived from the NM Statewide Orthophotography Project source imagery flown at 35,000 feet above average ground using multiple source images for each DOQQ. NM Statewide Orthophotography Project imagery was flown during the irrigation season, hence leaf-on for deciduous vegetation. These data depict 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 and reference. 2005 Aerial Photography Date for aerial photo source.

Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.1.0.722 U.S. National Park Service, NRPC, NR-GIS 20090721 remote-sensing image Source images are collected with a digital sensor with 4096 brightness values (12 bit) per band. Each image's histogram is clipped at high and low values to increase contrast, and then a digital dodge is performed in order to reduce vignetting of brightness and darkness trends across the frame. Radiometry is verified by visual inspection of the digital orthophoto. Where possible, radiometry is verified by visual inspection of the digital orthophoto with the original unrectified image. Slight systematic radiometric differences may 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. Tonal balancing may be performed over a group of images during the mosaicking process which may serve to lighten or darken adjacent images for better color tone matching. All tagged data and image files are validated using commercial GIS software to ensure proper loading before being archived. This validation procedure ensures correct physical format and field values for tagged elements. Seam lines and the tile edges are visually inspected. Orthorectified images are visually inspected for completeness to ensure that no gaps or image misplacements exist within the 3.75-minute image area or the overedge coverage. DOQQs are cloud-free imagery. DOQQs are produced with overedge coverage, ranging from a minimum of 300 meters to a maximum of 600 meters beyond the extremes of the NAD83 datum 3.75-minute latitude and longitude boundaries. The resulting DOQQ is a rectangle whose size may vary in relation to adjoining DOQQs. The DOQQ horizontal positional accuracy and the assurance of that accuracy depend, in part, on the accuracy of the data inputs to the rectification process (elevation data, aerotriangulation control and methods, camera calibration, scanner calibration, and source imagery parameters). DOQQs are produced to meet NMAS requirements for 1:12000-scale products. Quality control consisted of the contractor checking elevation data against current project control points for vertical discrepancies, and the U.S. Geological Survey checking orthorectified images against GPS collected roads and previous editions of the same DOQQ. 3001, Inc.

Source images are processed by the NPS Natural Resource GIS program staff in several steps. First, headers are extracted from source files where possible (usually only with band-interleaved images in ASCII format) and written to accompanying header (.hdr) files. World files (.blw) are written with positional data contained within. Source images are then processed by Lizardtech's GeoExpress software to produce lossless MrSID (.sid) images. These files are named with a convention incorporating the NPS abbreviation for the associated quadrangle name and the quadrant of this quadrangle the current DOQQ image applies to. These names are suffixed with "_L3" to denote the resulting file's "lossless-generation 3" status. Metadata are then created from each image via an automated routine that extracts specific data about each image, including image location and source date. The lossless images are then processed by GeoExpress one further time to create compressed (10:1) images. These images are used for live services and for distribution via the NPS Data Store. Compressed images carry a "_C3" suffix, denoting "compressed-generation 3." Finally, metadata are created for these images, and images are placed in the final directory structure on the GIS Data Server. Additionally, each image is zipped together with all of its components and uploaded to the NPS Data Store for public discovery and access. 20090721 U.S. National Park Service, NRPC, NR-GIS Unknown GIS Specialist mailing and physical address
