Pool 5a


Upper Mississippi River System (UMRS) Pool 5a is used to describe the region of the UMRS that is impounded by Lock and Dam 5a. It extends from Lock and Dam 5a located near Winona, Minnesota upstream to Lock and Dam 4 located near Whitman, Minnesota.

National Atlas and Seamless data server data have been moved to the National Map.

background information Aerial Photos (UMESC)

Orthoreferenced Color Infrared Images
In 2010, the EMP partnered with the USFWS to fly and acquire CIR digital aerial photography of Pools 1-13, Upper Mississippi River and Pools Alton–Marseilles, Illinois River at 8"/pixel and 16"/pixel respectively using a mapping-grade Applanix DSS439 digital aerial camera . The photography was collected at a minimum accuracy of 5-10 meters. These are the orthorectified photo mosaics for all or portions of the coverage area. The flights occurred during times of peak vegetation biomass, from August 13, 2010 through September 1, 2010. The mosaics are served as orthoreferenced JPEG2000 images.

On occasion the Center will scan and register aerial photography for special projects. As these data sets are created they're also made available through Web site. For information on how to download these data and obtain a free viewer program or the required .dll files for your GIS program, activate the help button.

background information Aquatic Areas (UMESC)

The Aquatic Areas data sets were created to identify areas of similar aquatic habitats. These data are available as polygons and linears. The linear data set contains data for features too narrow to be mapped as polygons (e.g., wing dams, rip rap). For additional information, access the help button.

background information Digital LiDAR Derivatives

updatedLiDAR (Light Detection And Ranging) data are remotely sensed, high-resolution elevation data collected by airplane. The Upper Midwest Environmental Sciences Center processed these data to create Digital Elevation Models (DEMs), 0.5 meter contour lines, and pool-wide hillshade images. A second tier of data processing has been completed for this pool. These processes include water-masking, contour-smoothing, point reclassification, where needed, and additional quality control steps. The collection and processing of these data were funded by the U.S. Army Corps of Engineers Environmental Management Program (EMP) and the Long Term Resource Monitoring Program (LTRMP).

background information Digital Orthophoto Quadrangles (DOQ)

Digital orthophoto quadrangles (DOQ) are georeferenced images of aerial photographs that have had camera orientation and terrain displacements removed.

These data are being compressed and redistributed through this web site as a service for program partners of the Upper Midwest Environmental Sciences Center. If you require data for areas outside the Mississippi River floodplain, data sets made from photographs from a different year, or the uncompressed files, contact the EROS Data Center.

background information Digital Raster Graphics (DRG)

Digital raster graphic (DRG) files are scanned and rectified images of USGS quadrangles.

These data are being compressed and redistributed through this web site as a service for program partners of the Upper Midwest Environmental Sciences Center. If you require data for additional areas, the help button access information on which files are available through this Web site, the USGS National Mapping Center in Rolla, Missouri keeps a listing of sites that distribute DRG files through the Internet, and copies of the data can be ordered from the EROS Data Center (for a duplication and distribution fee).

Land Cover/Use

Since 1989 the Upper Midwest Environmental Center through its association with the Long Term Resource Monitoring Program has been creating land cover/use data sets for the Upper Mississippi River system. For background information on how these data sets were created and are attributed, activate the help buttons. A link to a freeware GIS data viewer that can read the Shape files is also available on the file format/data transfer information page.

background information Land/Water (UMESC)

Land/water is one of the classification attributes in the land cover/use data sets created by UMESC from aerial photography. These data are redistributed here as shape files with the boundaries of the region's 1:24,000-scale USGS quadrangles added to the data. This has been done because individuals working with ArcView have reported numerous problems if they attempt to perform a dissolve on the land cover/use data to create a land/water only shape file. Most printers cannot process the detailed land/water boundaries unless some form of a break line or lines are added.

background information River Miles (UMESC and SAST)

The U.S. Army Corps of Engineers use a river mile measuring scheme to locate features on the Mississippi River. Two digital version of these data are available, one created by UMESC from stored on USGS quadrangles, and one created by the SAST project. The SAST data set differs from the UMESC data set in that some of the river mile markers were relocated by UMESC staff so they would fall within the navigation channel.
