WROC Aerial Mosaic (WTM) Dane County, WI 2020
- Description:
-
Resource provided by WisconsinView. Ayres Associates was contracted through the North Central Wisconsin Regional Planning Commission (NCWRPC) for the creation of 12-inch pixel resolution county mosaics and DOQQ tiles from the native resolution digital orthoimagery produced under the Wisconsin Regional Orthoimagery Consortium (WROC) in 2018-20. This project established county mosaics and DOQQ tiles for state and federal partners using WROC member data acquired under the Consortium. Please refer to http://ncwrpc.org/WROC2020/ more information on the Consortium. The coverage area included all 72 counties in Wisconsin which was flown in spring 2018, spring 2019, and spring 2020 under leaf-off conditions. The 4-band (RGB-NIR) aerial imagery was collected using Vexcel UltraCam Eagle, Leica ADS 100, and Leica DMCIII sensors outfitted in a fixed-wing aircraft with onboard GNSS/IMU systems and gyro-stabilized mounts. The native resolution aerial imagery was acquired to support 3-inch, 6-inch, and 12-inch ground sample distance (GSD) specifications. Resultant orthoimagery was rectified to DEMs created from new and existing LiDAR data. Orthoimagery was delivered in GeoTIFF format. The re-sampled statewide 4-band, 12-inch pixel DOQQ orthoimagery was produced to meet or exceed a horizontal accuracy standard of 4.8 feet at 95% confidence level according to ASPRS positional accuracy standards for digital geospatial data.
