Description:Aerial orthophotos of Snohomish County, Washington, USA, at 3" and 9" resolution taken between 20200413 and 20200713.
The dataset consists of tiled orthogonal imagery produced from nadir images captured by Pictometry International. 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
