Description:
Abstract:
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) from 1:15,000-scale color infrared aerial photos. These data have been used to create a variety of products, one of which is a data set used to classify aquatic areas. The 1989 and 1991 aquatic areas data sets were created by first generalizing the available land cover/use data into a land/water data set, then reinterpreting the aerial photography within the areas classified as water to determine the type of aquatic area. Area coverage for this data set is the Upper Mississippi River between Minneapolis, MN and Cairo, IL, and the Illinois River from its confluence with the Mississippi to Joliet, IL. Most of the individual data files were created from 1989 land cover/use data, except for the La Grange navigation pool on the Illinois River. Due to high water conditions present in 1989, 1991 aerial photography and land cover/use data were used to create the La Grange data set.
Purpose:
The Upper Midwest Environmental Sciences Center administers the Long Term Resource Monitoring Program (LTRMP), authorized under the Water Resources Development Act of 1986 (Public Law 99-662). The mission of the LTRMP 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.
Supplemental_Information:
The aquatic areas shape files are distributed in a Universal Transverse Mercator (UTM) projection, zone 15, North American Datum 1927 (NAD27) and in North American Datum 1983 (NAD83). Where appropriate these data are also served in a UTM zone 16 projections in both NAD27 and NAD83.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The attribute accuracy for this data set is tested by manually comparing hard copy plots to the original base map or mylar overlay. Some comparison may be done on-screen if areas on the test plot are unclear. The attributes are also checked against an all-inclusive list of possible attributes for the data set. If needed the attributes are also verified to the photo interpretation for the data set.
Logical_Consistency_Report:
All polygon features are checked for topology using the ARC/INFO software. Each polygon begins and ends at the same point with the node feature. All nodes are checked for error so that there are no dangling features. There are no duplicate lines or polygons. All nodes will snap together and close polygons based on a specified tolerance. If the node is not with the tolerance it is adjusted manually. The tests for logical consistency are performed in ARC/INFO.
Completeness_Report:
All data that was photo-interpreted is also automated.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The horizontal positional accuracy is tested by visual comparison of the data with hard copy maps and on-screen with existing data sets that cover the same area. The basemaps onto which the aerial photo overlays were transferred were 1:12,000-scale mylars plots of digital orthophoto quadrangles (DOQ) or 1:15,000-scale plots of digital raster graphics (DRG) created from 1:24,000-scale USGS quadrangles. Since DOQ data are positionally more accurate and are easier to align aerial photos than DRG data, DOQ data are used whenever possible.

A digital raster graphic (DRG) is a scanned image of a U.S. Geological Survey (USGS) standard series topographic map, including all map collar information. The image inside the map neatline is georeferenced to the surface of the earth and fit to the Universal Transverse Mercator projection. The horizontal positional accuracy and datum of the DRG matches the accuracy and datum of the source map. The map is scanned at a minimum resolution of 250 dots per inch.

Other_Citation_Details:
A digital orthophoto is a digital image of an aerial photograph in which displacements caused by the camera and the terrain have been removed. It combines the image characteristics of a photograph with the geometric qualities of a map. The standard digital orhthophoto produced by the USGS is a black-and-white, or color infrared, 1-meter ground resolution quarter quadrangle image. The accuracy and quality of USGS digital orthophotos must meet National Map Accuracy Standards at 1:12,000 scale for 3.75-minute quadrangles and at 1:24,000-scale for 7.5-minute quadrangles.
