Abstract
The dataset consists of tiled orthogonal imagery produced from nadir images captured by Pictometry International for Milwaukee and Kenosha counties in Wisconsin. Automatic aerial triangulation (AAT) was performed. The triangulated frames were rectified to a LiDAR derived DEM. Mosaicking was performed using an automatic seaming algorithm and manually edited to eliminate seams through elevated features where possible.
Purpose
Orthogonal image mosaic to support the needs of Milwaukee and Kenosha counties. Other uses expected.
Supplemental Information
Archived dataset at UW-Madison.
