This project established digital, 4-band orthoimagery services for Dane County, Wisconsin as part of FlyDane and the Wisconsin Regional Orthoimagery Consortium (WROC). Ayres Associates provided Dane County, Wisconsin, with digital, 4-band orthoimagery services in 2024 as part of FlyDane/WROC. The aerial imagery was collected on: March 6th, 7th, 9th, 13th, 15th, and 28th using a Vexcel UltraCam Eagle M3 sensor mounted in a fixed-wing aircraft. Aerial imagery was collected to support 0.25 foot ground sample distance (GSD) orthoimagery to meet ASPRS Class II horizontal accuracy specifications at 1 inch =50 feet map scale. The 3-inch pixel orthoimagery was produced to meet or exceed a 1.2 foot horizontal accuracy at 95% confidence level, according to ASPRS Positional Accuracy Standards for Digital Geospatial Data. Resultant orthoimagery was rectified to a DEM created from newly acquired LiDAR collected in 2024. Orthoimagery was delivered in PLSS quarter-section GeoTiff and MrSID tiles and a project wide MrSID mosaic. The project area covers approximately 1250 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 Dane County in 2024 to provide consistent deliverable products and accuracy standards for each of the participating entities.
