Description: Ayres Associates provided the City of Belvidere, Illinois with digital, color orthoimagery services in 2017. The aerial imagery was collected on April 1st using a Leica RCD 30 sensor mounted in a fixed-wing aircraft. Aerial imagery was collected to support the 3-inch resolution orthoimagery which will conform to National Map Accuracy Standards for 1” = 50’ map scale. This translates to +/- 1.7’ at the 90% confidence level. Resultant orthoimagery was rectified to a DEM created from existing LiDAR data. Orthoimagery was delivered in PLSS quarter section GeoTiff and MrSID tiles and a project-wide MrSID mosaic.
