This project established digital, 4-band orthoimagery for Clark County, Wisconsin as part of the Wisconsin Regional Orthoimagery Consortium (WROC). Ayres Associates provided Clark County, Wisconsin with digital, 4-band orthoimagery services in 2023 as part of WROC. The aerial imagery was collected on April 12th, 13th, 14th, 26th, and May 3rd using a Microsoft Vexcel UltraCam Eagle M3 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 specifactions 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, 2014. Resultant orthoimagery was rectified to a DEM surface created from countywide QL2 lidar data acquired in 2018. Orthoimagery was delivered in PLSS section GeoTiff and MrSID tiles and a project-wide MrSID mosaic. The orthoimagery was delivered according to a section tile schematic. Supplemental Information: The Wisconsin Regional Orthoimagery Consortium (WROC) is a multi-entity group of county members and partners led by representatives from Ayres Associates and the North Central Wisconsin Regional Planning Commission (NCWRPC). 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 Clark County in 2023 to provide consistent deliverable products and accuracy standards for each of the participating entities.
