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.", "summary": "2020 Aerial Imagery from Ayers and Associates", "title": "Aerial_2020", "tags": [ "Aerial", "Aerial Imagery", "Orthoimagery", "2020", "WROC", "Ayres", "3-inch pixel", "4-band" ], "type": "Image Service", "typeKeywords": [ "Data", "Service", "Image Service", "ArcGIS Server" ], "thumbnail": "", "url": "https://maps.ci.janesville.wi.us/image", "minScale": 9229486.44180694, "maxScale": 4506.58517666354, "spatialReference": "NAD_1983_HARN_WISCRS_Rock_County_Feet", "accessInformation": "", "licenseInfo": "", "_ssl": true }
