| description:
|
Ayres Associates provided Jersey County, Illinois with digital, color orthoimagery services in 2016. 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. |
