2017 True Color Mosaic, Emiquon Preserve and Spunky Bottoms 2017 True Color Mosaic, Emiquon Preserve and Spunky Bottoms
The true color aerial imagery contained in this mosaic was collected on September 19, 2017 with a Phase One iXU-R 180 aerial camera system. The mission was flown at approximately 1,200 meters above ground level resulting in a ground sample distance of 0.15 meters/pixel (6"/pixel). The area of interest is the Emiquon Preserve and the mosaic is for the purpose of habitat monitoring.
UMRR HNA-II 2010/11 Level 3 Aquatic Areas - Upper Mississippi River System UMRR HNA-II 2010/11 Level 3 Aquatic Areas - Upper Mississippi River System
The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS). Aerial images of Pools 3-13 Upper Mississippi River System and Pools, Alton-Marseilles, Illinois River were collected in color infrared (CIR) in August of 2010 at 8”/pixel and 16”/pixel respectively using a...

Ottawa National Wildlife Refuge: 2014 Crane Creek Image mosaics Ottawa National Wildlife Refuge: 2014 Crane Creek Image mosaics
The aerial imagery contained in this mosaic was collected on July 17, 2014 with an Applanix 439 Digital Sensor System. These missions were flown at 6"/pixel and 8'/pixel resolution. These mosaics complement the land cover land use data by providing an image format to consider. A flight plan was not used and this resulted in incomplete coverage. The area of interest is the Crane Creek...

Mississippi National River and Recreation Area, 2012 True Color Aerial Mosaic Mississippi National River and Recreation Area, 2012 True Color Aerial Mosaic
Digital aerial imagery provides baseline data for mapping vegetation types and other land cover features. Vertical photographs (photographs taken with the aerial camera pointed straight down at the ground) collected with proper overlapping within each flight line permit an interpreter to study the photographs three-dimensionally with a stereoscope (Avery 1978) or, as with the Mississippi...
