The aerial imagery was collected on March 28th and April 10th using a Microsoft Vexcel UltraCam Eagle M3 sensor mounted in a fixed-wing aircraft. The imagery was collected to support 0.5 foot ground sample distance (GSD) orthoimagery to meet ASPRS Class II horizontal accuracy specifications at 1"=100' map scale. The 6-inch pixel orthoimagery was produced to meet or exceed a horizontal accuracy of 1.4 feet RMSE according to ASPRS Positional Accuracy Standards for Digital Geospatial Data, 2014. Resultant orthoimagery was rectified to a DEM surface created from existing LiDAR data. Orthoimagery was delivered in PLSS section GeoTiff and MrSID tiles and a project wide MrSID mosaic. The orthoimagery was delivered according to a quarter-section tile schematic.
