    Description:

    Abstract: This data set consists of digital orthophoto images obtained from 1:20,000 scale black-and-white aerial photography aquired in the spring of 2000. The orthophoto files are prepared at two different scales: 1""=400' and 1""=200'. Each 400-scale image nominally covers four U.S. Public Land Survey System sections, for a total of 148 digital image files in the 400-scale data set. The pixel resolution of the 400-scale imagery is two feet on the ground, and the files contain overlap between images. Each 200-scale image covers a USPLSS Survey Township, for a total of 16 images in the 200-scale data set. The pixel resolution of the 200-scale imagery is one foot on the ground, again with overlap between images. The 1"=400 scale orthophoto files are in GeoTIFF format with accompanying ""world"" (tfw) files, and the 1"=200' scale orthophoto files are in MrSID compressed format with the accompanying sid "world" (sdw) files.
    Purpose: This data set was collected to provide an inventory of orthophoto images of Southeastern Wisconsin and to be used for broad regional planning purposes. The images were provided to Waukesha County for internal use, as well as for distribution as requested.

    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 (400-scale images) or one foot on the ground (200-scale images).
    Completeness Report: The digital orthophoto images in this data set cover all of Waukesha County, and small portions of Jefferson County in Wisconsin.
    Positional Accuracy:

    Horizontal Positional Accuracy:
    Horizontal Positional Accuracy Report: The 400-scale orthophoto images in this data set were prepared to meet National Map Accuracy Standards for 1:4800 scale mapping. The resolution of each pixel in the 400-scale files is two feet on the ground. Therefore, ninety percent or more of all well-defined planimetric features visible in the 400-scale imagery are within approximately 15 feet of their true position on the ground. The 200-scale orthophoto images in this data set were prepared to meet National Map Accuracy Standards for 1:2400 scale mapping. The resolution of each pixel in the 200-scale files is one foot on the ground. Therefore, ninety percent or more of all well-defined planimetric features visible in the 200-scale imagery are within approximately 8 feet of their true position on the ground.

    Entity and Attribute Information - Section Index
    Overview Description:
    Entity and Attribute Overview: The 400-scale data set consists of a set of 148 black-and-white orthophoto images, with each image covering four U.S. Public Land Survey System sections. Each digital raster image file is approximately 32 megabytes in size, and is formatted in GeoTIFF (Tagged Image File Format). The pixel resolution of the images is two feet on the ground, with areas of overlap between adjacent images. The orthophoto files are named according to the U.S. Public Land Survey System 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); 3) 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); and 4) a text resource file containing font information for display of the vector and text file (DGN file) in MicroStation format (""ortho.rsc"" file name). The 200-scale data set consists of a set of 16 black-and-white orthophoto images, with each image covering a USPLSS Survey Township. Each digital raster image file is approximately 62 megabytes in size, and is formatted in MrSID (.sid) compressed image file format). The pixel resolution of the images is one foot on the ground, with overlap between adjacent township images. Each image file includes an accompanying MrSID-format world file (.sdw) containing the coordinate information used to display and register the image in most GIS softwares.
    Entity and Attribute Detail Citation: Additional information about the orthophoto images and ancillary files is contained in a two-page document entitled "Year 2000 SEWRPC Regional Orthophotography Program: Description of Digital Products" available from the Southeastern Wisconsin Regional Planning Commission, GIS Division or the Waukesha County Land Information Office.
