2021 Illinois Waterway Aerial Imagery Mosaics - La Grange - North 4-Band
The Corps of Engineers' Rock Island District is planning an unprecedented closure of the Illinois Waterway in 2020 in order to perform required maintenance on locks. Aerial imagery will document river conditions prior to the closure (2019) and after the locks are reopened (2021). Under a separate but related effort, aerial imagery of the entire Illinois Waterway will be collected in 2020 as part of the decadal Upper Mississippi River System Land Cover/Land Use mapping project. The imagery has a resolution of approximately 0.4 meter/pixel (16 inches). The imagery was collected on September 16 and 17, 2021 with a Phase One iXU-R 180 RGB camera co-mounted with a Phase One iXU-RS 160 Achromatic camera to create 4-band imagery that can be displayed as either true-color (RGB) or color-infrared (CIR).
