The aerial imagery was collected on February 29, using a Leica Geosystems RCD30 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 horizontal accuracy meets or exceeds 1.0 feet RMSE using the National Standards for Spatial Data Accuracy (NSSDA) standards. Resultant orthoimagery was rectified to a new DEM from existing LiDAR created as part of the Illinois Height Modernization Program (ILHMP). Orthoimagery was delivered in PLSS quarter-section GeoTiff and MrSID tiles and a project-wide MrSID mosaic. The orthoimagery was delivered according to a quarter-section tile schematic.", "summary": "This project established digital, color orthoimagery for Jersey County, Illinois.", "title": "Fieldon_2016_sid", "tags": [ "digital", "color", "orthoimagery", "3-inch" ], "type": "Image Service", "typeKeywords": [ "ArcGIS Server", "Data", "Image Service", "Service" ], "thumbnail": "", "url": "https://arcimagery01.hornershifrin.com/arcgis/", "minScale": 72098.68936591766, "maxScale": 281.63550533561585, "spatialReference": "NAD_1983_StatePlane_Illinois_West_FIPS_1202_Feet", "accessInformation": "", "licenseInfo": "Not to be used for purposes other than those strictly outlined in the 2016 Jersey County Orthophotography Initiative.", "portalUrl": "" }
