Service Description: Ayres Associates provided Lafayette County, Wisconsin with digital, 4-band orthoimagery services in 2023 as part of WROC. The aerial imagery was collected on April 6th and 8th 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 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 created from existing LiDAR acquired in 2019. Orthoimagery was delivered in PLSS section GeoTiff and SID tiles and a project wide SID mosaic. The orthoimagery was delivered according to a PLSS section tile schematic. The project area covers approximately 634 square miles. Supplemental Information: The Wisconsin Regional Orthoimagery Consortium (WROC) is a multi-entity group led by regional planning commissions (RPCs) and WROC respresentatives 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 Lafayette County in 2023 to provide consistent deliverable products and accuracy standards for each of the participating entities.
