This project established digital, 4-band orthoimagery for Juneau County, Wisconsin as part of the Wisconsin Regional Orthoimagery Consortium (WROC). Ayres Associates provided Juneau County, Wisconsin, with digital, 4-band orthoimagery services in 2025 as part of WROC. The aerial imagery was collected on April 6th, 12th, 13th, 16th, 26th, May 4th, and 8th using an UltraCam Eagle 4.1 sensor at 7.25 cm GSD mounted in a fixed-wing aircraft. Aerial imagery was collected to support 0.25 foot ground sample distance (GSD) orthoimagery at 1 inch = 50 feet map scale. The 3-inch pixel orthoimagery was produced to meet or exceed 0.66 foot RMSEH according to ASPRS Positional Accuracy Standards for Digital Geospatial Data 2024. Resultant orthoimagery was rectified to a DEM created from existing lidar. Orthoimagery was delivered in GeoTiff and MrSID tiles and a project-wide MrSID mosaic. The orthoimagery was delivered according to a PLSS quarter section tile schematic. The project area covers approximately 804 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 Juneau County in 2025 to provide consistent deliverable products and accuracy standards for each of the participating entities.
