This project established digital, 4-band orthoimagery for Washburn County, Wisconsin as part of the Wisconsin Regional Orthoimagery Consortium (WROC). Ayres Associates provided Washburn County, Wisconsin with digital, 4-band orthoimagery services in 2024 as part of WROC. The aerial imagery was collected on April 13th and 14th using a Leica Geosystems 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 inch = 100 feet 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. Resultant orthoimagery was rectified to a DEM created from existing LiDAR acquired in 2016. Orthoimagery was delivered in PLSS section GeoTiff and MrSID tiles and a project wide MrSID mosaic. The project area covers approximately 853 square miles. Supplemental Information: The Wisconsin Regional Orthoimagery Consortium (WROC) is a multi-entity group of county members and partners led by regional planning commissions (RPCs) and WROC representatives from Ayres Associates. The goal of the consortium is to build and sustain a multi-participant program to acquire digital orthoimagery and elevation data throughout Wisconsin. Orthoimagery was collected for Washburn County in 2024 to provide consistent deliverable products and accuracy standards for each of the participating entities.
