    Description:
    Abstract: This data set consists of digital orthophoto images obtained from 1:20,000 scale black-and-white aerial photography acquired in the spring of 1995. Each image nominally covers four U.S. PublicLand Survey System sections, for a total of 146 digital image files in the data set. The pixel resolution of the imagery is two feet on the ground. The files are in TIFF format.

    Purpose: This data set was collected to provide an inventory of orthophoto images of Waukesha County, Wisconsin and to be used for broad regional planning purposes.

    Data Quality Information - Section Index
    Logical Consistency Report: This raster data set contains pixels with values that represent relative brightness. Each pixel represents two feet on the ground.

    Completeness Report: The digital orthophoto images in this data set cover the entire County, and a small portion of, Jefferson County in Wisconsin.
    Positional Accuracy:

    Horizontal Positional Accuracy:
    Horizontal Positional Accuracy Report: This data set was prepared to meet National Map Accuracy Standards for 1:4800 scale mapping. The resolution of each pixel in the raster files is two feet on the ground. Therefore, ninety percent or more of all clearly-defined planimetric features visible in the imagery are within approximately 15 feet of their true position on the ground.

    Overview Description:
    Entity and Attribute Overview: This data set consists of a set of 146 black-and-white orthophoto images, with each image covering four U.S. Public Land Survey System sections. Raster images are available in GeoTiff format (approx. 32 Mb in size), and MrSID format (approx. 2.0 Mb in size). GeoTIFF is a non-proprietary geographic TIFF format. The purpose of GeoTIFF is to provide information that lets raster imagery be read automatically into correct position and scale within many GIS softwares. The MrSID files are the original TIFF images post processed using the MrSID compression software, to create much smaller data files. The compression ratio used on to create the MrSID files was 15:1. The pixel resolution of the images in both formats is two feet on the ground. The orthophoto files are named according to the U.S. Public Land Survey Syatem township, range, and four-section area covered by the image. In addition, a number of ancillary digital files are available that complement the orthophoto image files. These include: 1) a generic ASCII-format text file containing the State Plane coordinates of the extent of the image (".bnd" file extension); 2) an ESRI-format world file containing the coordinate information used to display and register the image in ESRI software (".tfw" file extension); 4) a symbolized vector and text file containing U.S. Public Land Survey System section and quarter-section corners and lines and map legend and title information in MicroStation format (".dgn" file extension); 4) a text resource file containing font information for display of the vector and text file in MicroStation format ("SEW.rsc" file name); 5) a MrSID-format world file containing the coordinate information used to display and register the image in MrSID software (".sdw" file extension).
    Entity and Attribute Detail Citation: Additional information about the orthophoto images and ancillary files is contained in two one-page documents entitled ""Orthosid.doc"" and "Orthotif.doc" available from the Waukesha County Land Information Office.
