Janis Ruhser 20171005 Vector Digital Data Set (Polygon) https://doi.org/10.5066/P1JXDRET The U.S. Geological Survey's Upper Midwest Environmental Sciences Center (UMESC) has created high-resolution land cover/use data sets for the Upper Mississippi River System (UMRS). Aerial images of Pools 1-13 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 mapping-grade Applanix DSS 439 digital aerial camera. In August 2011, CIR aerial images of Pools 14-Open River South, Upper Mississippi River and Pools Dresden-Lockport, Illinois River were collected at 16”/pixel with the same camera. The CIR aerial images were interpreted and automated using a 31-class LTRM vegetation classification. These data have been used to create a variety of products, one of which is a data set used to classify aquatic areas. The 2010/11 aquatic areas data sets were created by first generalizing the available land cover/use data into a land/water data set, then reinterpreting the areas classified as water to determine the type of aquatic area. The geographic extent of the UMRS is the Mississippi River floodplain from Cairo, IL to Minneapolis, MN and the Illinois River floodplain from its confluence with the Mississippi near Grafton, IL to Lake Michigan. The Upper Midwest Environmental Sciences Center administers the US Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) Program, Long Term Resource Monitoring (LTRM) element, authorized under the Water Resources Development Act of 1986 (Public Law 99-662). The mission of the UMRR-LTRM is to provide decision-makers with information to maintain the Upper Mississippi River System (UMRS) as a viable large river ecosystem given its multiple-use character. The long-term goals of the program are to understand the system, determine resource trends and impacts, develop management alternatives, manage information, and develop useful products. The creation and distribution of aquatic areas data for the UMRS aids the Center in meeting these goals through the Habitat Needs Assessment II (HNA-II) project. The HNA-II will utilize many new data and information products, as well as modeling approaches that were stated as limitations of HNA-I. In addition, previous efforts to document desired future conditions of the UMRS will be incorporated into the assessment. Finally, additional input from river resources and other technical teams will help guide the process. 20100801 20110831 ground condition Complete None planned -91.533114964 -91.147437769 39.938033142 39.605395351 None Main Channel Backwater Impoundment Navigation Channel Shallow Floodplain Alexandria Digital Library Feature Type Thesaurus wetlands USGS Thesaurus water resource management USGS Metadata Identifier USGS:59d69658e4b05fe04cc6b348 None Mississippi River Pool 22 Common geographic areas Illinois Missouri None None U.S. Geological Survey, Midwest Region Janis Ruhser Biologist Mailing and Physical

All polygon features are checked for topology using ArcGIS. All data that were photo-interpreted were also automated. Boundary changes over time have led to No Coverage areas in some locations. The horizontal positional accuracy was tested against the base layer land cover/use data. No additional tests were performed. Not applicable.

The rest of the Aquatic Areas were attributed on screen, with polygon boundaries delineated where necessary, according to a generalized version of the classification described here: http://www.umesc.usgs.gov/documents/reports/1993/93t003.pdf Wilcox, D.

No minimum mapping unit was defined for the aquatic areas, with the exception of Contiguous Floodplain Lake (CFL) which shall not be delineated when smaller than 0.04 ha. 20170615 The original Main Navigation Channel was adjusted where it appeared to cross structures, islands, or shorelines. Channel Border polygons were also adjusted to encompass structures, smooth borders to other aquatic areas, and extend to shorelines where applicable. The United States Army Corps of Engineers - Army Geospatial Center - Inland Electronic Navigation Chart was used to assist in these delineations. 20170615 Vector G-polygon 230 Universal Transverse Mercator 15 0.9996 -93.0 0.0 500000.0 0.0 coordinate pair 0.6096 0.6096 Meter D_North_American_1983 GRS_1980 6378137.0 298.257222101 Attribute Table Table containing attribute information associated with the data set.
