Ayres Associates provided the City of Janesville, Wisconsin with digital, 4-band orthoimagery services in 2020 as part of WROC. The aerial imagery was collected on April 2nd and 18th using a Microsoft 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" = 50' map scale. The 3-inch pixel orthoimagery was produced to meet or exceed a horizontal accuracy of 0.7 foot RMSE according to ASPRS Positional Accuracy Standards for Digital Geospatial Data. Resultant orthoimagery was rectified to a DEM created from LiDAR newly acquired in 2020. Orthoimagery was delivered in PLSS quarter-section GeoTiff and MrSID tiles and a project wide MrSID mosaic. The project area covers approximately 47 square miles. |
