<div style='text-align:Left;font-size:12pt'><div><div><p><span>Columbia County 3 inch pixel orthophotography. Ayres Associates provided Columbia County, Wisconsin, with digital, 4-band orthoimagery services in 2025 as part of WROC. The aerial imagery was collected on March 11th, 12th, and April 6th using a Leica Geosystems DMC III 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"=50' 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 lidar previously collected in 2020. 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 796 square miles.</span></p></div></div></div> |
