This project established digital, color orthoimagery for Grant County, Wisconsin as part of the Wisconsin Regional Orthophotography Consortium.
<div style='text-align:Left;'><div><div><p style='margin:0 0 0 0;'><span><span>Ayres Associates provided Grant County, Wisconsin, with digital color orthoimagery services in 2015 as part of WROC. The aerial imagery was collected on April 11, 2015, using a Leica Geosystem ADS100 sensor mounted in a fixed-wing aircraft. Aerial imagery was collected to support 1.0 foot ground sample distance (GSD) orthoimagery to meet ASPRS Class II horizontal accuracy specifications at 1” = 200’ map scale. The horizontal accuracy meets or exceeds 4.0 feet RMSE using the National Standard for Spatial Data Accuracy (NSSDA) standards. Resultant orthoimagery was rectified to the new DEM from existing LiDAR 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 four section tile schematic. The total project area is 1180 square miles, plus a 500-ft buffer around the county boundary. Geographic Description: Grant County is located in southwestern Wisconsin in the Western Uplands area of the state. The county's northern and western boundaries are formed by the Wisconsin and Mississippi rivers, respectively. Urban areas include the cities of Platteville and Lancaster, though the county is primarily made up of agricultural land and forests. 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 Grant County in 2015 to provide consistent deliverable products and accuracy standards for each of the participating entities.</span></span></p><p><span /></p></div></div></div>
