Description: Ayres Associates provided Goodhue County, Minnesota with digital, color orthoimagery services in 2018. The aerial imagery was collected on April 29th using a DMC III 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 horizontal accuracy meets or exceeds 2.0 feet RMSE using the National Standard for Spatial Data Accuracy (NSSDA) standards. Resultant orthoimagery was rectified to a DEM surface created from existing state LiDAR data. Orthoimagery was delivered in custom-named PLSS section GeoTiff and MrSID tiles, township MrSID tiles, a MrSID mosaic for the City of Red Wing and a county-wide MrSID mosaic. The total project area is 935 square miles, which includes a buffer around the county boundary.
