Description: Ayres Associates provided Goodhue County, Minnesota with digital, 4-band orthoimagery services in 2020. The aerial imagery was collected on March 31st using a Leica Geosystems DMCIII sensor mounted in a fixed-wing aircraft. Aerial 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 foot RMSE according to ASPRS Positional Accuracy Standards for Digital Geospatial Data. Resultant orthoimagery was rectified to a DEM created from LiDAR newly acquired in 2020. Orthoimagery was delivered in PLSS section GeoTiff and MrSID tiles, township MrSID tiles and a project wide MrSID mosaic. The project area covers approximately 935 square miles.
