Description:
Abstract:
"This data set consists of 1-foot pixel resolution natural color orthoimages covering Orange County, Florida. 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. The design accuracy is estimated not to exceed 7.6-feet diagonal error."
Purpose:
"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."
Supplemental_Information:
The data obtained through The Seamless Server is considered to be the "best available" data from USGS. Historical data and other data may be obtained by contacting Customer Services, Center for Earth Resources Observation & Science, at 1-800-252-4547. Information in quotation marks, initial processing steps, accuracy reports, and source information is taken directly from the original metadata.Spatial-specific information not available

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
"Radiometry is verified by visual inspection of the digital orthophoto. 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."
Logical_Consistency_Report:
"All GeoTIFF tagged data or TIFF6.0 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."
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 seasons in deciduous vegetation regions. The source imagery from the Florida Department of Revenue covers Orange County. There are void areas along the edges of the county boundaries that extend into adjacent state and county areas. These void areas have a radiometric value of either zero (black) or 128 (uniform gray)."
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
"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 positions of photo-identified ground control were evaluated on the GeoTIFF image and compared with their ground values in order to determine an overall accuracy for the final area of coverage. After image coordinate measurement was completed, a radial error was calculated for the entire block. This value is an estimate of the horizontal accuracy of the tile expressed in feet."

Entity_and_Attribute_Information:
Overview_Description:
Entity_and_Attribute_Overview:
Natural color orthoimagery is organized in three color bands or channels which represent the red, green, and blue (RGB) portions of the spectrum. Each image pixel is assigned a triplet of numeric values, one for each color band. Numeric values range from 0 to 255. Areas where data is incomplete due to lack of full image coverage are represented with the numeric value of 0.
