This metadata record describes the .5-foot pixel resolution digital orthoimagery produced for the Jefferson County by the Sanborn Map Company. This orthoimagery is provided 4-band (R, G, B, NIR), 8-bit per pixel and delivered in section tiles in uncompressed TIFF/TFW and compressed SID/SDW (20:1) format. A compressed mosaic is also provided in SID/SWD format (20:1). The data was flown on April 14th, 15th, and 18th of 2015 using an UltraCam Eagle camera and complies with the American Society for Photogrammetry and Remote Sensing Accuracy Standards (ASPRS) for Class 1, large scale maps at 1" = 100'. This orthoimagery is published in State Plane Wisconsin South Coordinate System NAD83 (US Survey Feet). The Vertical datum is National American Vertical Datum of 1988 (NAVD88).
Rectified orthoimagery for Jefferson County to serve as a basemap for GIS applications.

N/A
Attribute accuracy does not apply to orthoimagery.
N/A
Since the ortho images are raster products, the logical consistency is based on how well the images fit between image tiles and between individual photo frames use to produce the ortho mosaics. The images match within four pixels of each other through out the project area.
The ortho image tiles are checked for missing pixels, gaps, overlaps and other anomolies generally associated with digital orthophoto products. The ortho tiles are checked and any discrepencies are resolved through the use of proprietary and industry editing tools. Once the images ard copied to the deliverable media they are further check for naming, image completeness, and image ability to be opened in ArcMap.
This orthoimagery meets ASPRS Class 1 Accuracy Standards for 1"=100' scale mapping
Specification requires that data meet a .5' RMSE requirement. Points were surveyed and compared to location within the orthophoto and found meet this specification.
.5-foot RMSE
N/A
Orthoimagery does not have inherent vertical accuracy.

Image Acquisition by Sanborn Map Company, April 14th, 15th, and 18th of 2015 , Using a UltraCam Eagle Camera. Imagery and GPS/IMU data is downloaded from disc on the plane to disc on the ground. GPS/IMU mission data is processed together with simultaneously collected ground-based GPS base station data in forward and reverse directions. This precisely determines the aerial camera's position and orientation in the terrain (project) coordinate system and allows for correct orientation of the imagery.

Orthoimagery is rectified using the AT solution and LiDAR. Once rectified, the orthoimagery is colorbalanced to the acceptable parameters established by the customer. Orthoimagery then undergoes manual quality control to check for issues as outlined in the Digital Orthoimagery Acceptance Criteria document. Issues such as warps, smears, misalignments, etc. are corrected using proprietary tools and Adobe PhotoShop. Upon completion of the QC process, the orthos are provided to the client for review in uncompressed TIFF/TFW and compressed SID/SDW (20:1) format. A compressed mosaic is also provided in SID/SWD format (20:1).

Geodetic ground control is used to create a digital control file and control report as well as QC check of ortho accuracy. Predefined points within the project area are targeted and photo-identifiable locations are measured. These points along with their precise coordinates are used in the AT process and to check the horizontal accuracy of the resulting orthophotos.
