Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>The dataset consists of orthogonal imagery produced from nadir images captured by Pictometry International and is set for the Pennsylvania State Plane South projection. Automatic aerial triangulation (AAT) was performed. The triangulated frames were rectified to a Lancaster County DEM derived from ql2 LIDAR. Mosaicing was performed using an automatic seaming algorithm and manually edited to eliminate seams through elevated features where possible. Photos were taken between March 2016 and May 2016. The following is an accuracy statement from Pictometry International: 6-inch GSD: RMSE(x or y) 1.30 ft; RMSE(r) 1.84 ft; NSSDA (95%) 3.20 ft.</SPAN></P></DIV></DIV></DIV>
