An orthoimage is remotely sensed image data in which displacement of features in the image caused by terrain relief and sensor orientation have been mathematically removed. Orthoimagery combines the image characteristics of a photograph with the geometric qualities of a map. Each orthoimage provides imagery over a DOQQQ with a 100-meter image overlap between adjacent files. The projected coordinate system is UTM Zone 10 North with a NAD83 datum. This data depicts geographic features on the surface of the earth. It was created to provide easily accessible geospatial data which is readily available to enhance the capability of Federal, State, and local emergency responders, as well as plan for homeland security efforts. This data also supports The National Map.

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. Horizontal Positional Accuracy The horizontal positional accuracy and the assurance of that accuracy depend, in part, on the accuracy of the data inputs to the rectification process. The location of existing photoidentifiable ground control and aerotriangulation points were evaluated on the GeoTIFF image and compared with their ground values in order to determine an overall accuracy for each test block of orthoimages within the project. After image coordinate measurement was completed for each block, an RMSE for the diagonal error was calculated for the orthoimages within the block. This value is an estimate of the horizontal accuracy of the tile expressed in meters.; Quantitative Value: 0.948 meters, Test that produced the value: Federal Geographic Data Committee, 1998, Geospatial Positioning Accuracy Standard, Part 3, National Standard for Spatial Data Accuracy, FGDC-STD-007.3-1998 Completeness Report Orthoimages are visually inspected for completeness to ensure that no gaps or image misplacements exist within and between adjacent images. These images are derived by mosaicking multiple images to ensure complete coverage. Source imagery is cloud free. Photography was flown during leaf-off in deciduous vegetation regions. Imagery along the eastern margin of the urban area coverage and falling outside of the urban area may contain some void areas. These void areas have a radiometric value of 0 (black). Conceptual Consistency All GeoTIFF tagged data and image file sizes 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. Seamlines and tile edges are visually inspected. Seamline mismatches are not corrected unless the overall displacement exceeds one meter. The rectification process requires, as input, a digital elevation model (DEM) gridded to user-specified bounds, a digital image file (PHOTO), and external orientation parameters for the aerial photograph which are typically derived from aerotriangulation (ATCONTROL). Four band imagery was collected at a flight elevation of 20,000 feet. Airborne GPS positions were computed by Photo Science, Inc. and used as control in the aerotriangulation process. The aerial images, AGPS data, ground check point data, and camera calibration data were used as inputs to the aerotriangulation process. ISAT 04.05 was used to perform block adjustments and generate exterior orientation parameters for each photo. The external orientation parameters were used to provide the geospatial control each photograph during orthorectification. Vertical control for the orthorectification process was obtained from existing USGS Digital Elevation Models (DEM). During the orthorectification process, elevation data were extracted and resampled to meet user-specified intervals and bounds. The orthorectified imagery is resampled to a 0.5 meter ground resolution with a ground extent of a DOQQQ, with 100-meter image overlap. Each DOQQQ orthoimage was generated from a mosaic created from multiple photographs. Orthoproduction was performed using the Intergraph Ortho Pro 4.4.18. Seamlines were Manually Generated and tone balanced between frames prior to cutting out into DOQQQ products. The orthorectified imagery is georeferenced to UTM zone 14, NAD83, meters. All orthoimages are individually inspected for content, misalignments along mosaic seamlines, and void areas. Source information was collected and verified manually during the production process. 2009-01-01T00:00:00 Source Contribution: Aerotriangulation provides the exterior orientation parameters (X, Y, Z, omega, phi, kappa) for input to the orthorectification process. | Type of Source Media: disc Aerotriangulation 2009-09-01 Source Contribution: Provides initial photo station positions to control aerotriangulation. | Type of Source Media: disc Airborne GPS 2009 Source Contribution: Provides ground coordinates used as reference for ABGPS and quality check for Orthophotographs. | Type of Source Media: disc Control 2009 Source Contribution: Source imagery for orthorectification process | Source Geospatial Form: remote-sensing image | Type of Source Media: disc Raw Frames 2009-06-27 Source Contribution: Used to provide ground elevations for orthorectification process. | Type of Source Media: CD-ROM USGS 10m National Elevation Dataset 2001-01-01 publication 1950 1954
