Service Description: Ayres Associates provided La Crosse County, Wisconsin with digital, color orthoimagery services in 2015 as part of WROC. The aerial imagery was collected on March 20th and 21st and April 4th and 11th using a Microsoft Vexcel UltraCam Eagle 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 horizontal accuracy meets or exceeds 2.0 feet RMSE using the National Standards for Spatial Data Accuracy (NSSDA) standards. Resultant orthoimagery was rectified to the new DEM from an existing LiDAR surface created as part of the CDBG funded WROC program. 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. The total project area is 543 square miles, plus a 500-ft buffer around the county boundary. Geographic Description: La Crosse County is located in western Wisconsin, in the heart of the driftless area, characterized by scenic ridges and narrow valleys. Because of these valleys, called coulees, the area surrounding La Crosse is commonly known as the Coulee Region. The western edge of the county lies along the Mississippi River, amid magnificent limestone bluffs, and where the cities of La Crosse and Onalaska are the primary urban areas. Supplemental Information: The Wisconsin Regional Orthophotography Consortium (WROC) is a multi-entity group 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 La Crosse county in 2015 to provide consistent deliverable products and accuracy standards for each of the participating entities.
