Description:

****Converted to NAD83(2011) by SEWRPC and ProWest & Associates Inc in January of 2019.This data set consists of 6-inch, natural color orthoimages covering the urban area footprint. 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.For the 6-inch GSD Ortho image, horizontal positional accuracy was designed not to exceed 3.80 feet NSSDA at the 95% confidence level.This dataset consists of uncompressed, ortho photo tiles formatted as 8-bit, 3-band (RGB), uncompressed, GeoTIFF images with TIF world files. Multi-spectral digital orthophotography was produced at a scale of 1:1200 (1" = 100') with a 6-inch pixel resolution over.  The project area includes a 1,000-foot buffer extension beyond the county boundaries.  Wisconsin State Plane Coordinate System grid, South Zone, NAD 1927.The MrSID files are color GeoTIFF files merged into compressed files covering larger areas. Each MrSID file for Ozaukee, Racine, Walworth, Washington, and Waukesha Counties covers approximately one U.S. Public Land Survey System survey township (about 36 square miles)This data depicts geographic features on the surface of the earth. This data set was collected to provide an inventory of orthophoto images in the Southeastern Wisconsin Region and to be used for broad regional planning purposes. 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. This dataset was automatically cataloged from the creator's Open Data Portal. In some cases, publication year and bounding coordinates shown here may be incorrect. Additional download formats may be available on the author's website.
