Illinois River - Alton

River Mile 0-80
Updated February 8, 2013
Alton

Alton is used to describe the unimpounded region of the Illinois River. It extends from the confluence of the Illinois and Mississippi Rivers located near Grafton, Illinois upstream to the La Grange Lock and Dam located south of Beardstown, Illinois.

Additional data sets are also available through the National Atlas, U.S. Geological Survey's Seamless Data Server, and the Natural Resource Conservation Service's Data Gateway.

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 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. Project status information, photography dates, and ordering information are available online.

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).

background information Hydrology (UMESC)

These data were created from USGS - National Mapping Division hydrology data. The data were modified to display tributaries of the Upper Mississippi River System (UMRS). If you require these data in their original format, contact the EROS Data Center. The files are available to download via. FTP, and regional CD-ROMs are also available.

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.

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.

SAST Data (SAST)

The Scientific Assessment and Strategy Team (SAST) project was created following the 1993 floods to collect and distribute data for the Upper Mississippi and Missouri river systems. Some of these data are redistributed through this web site as a service to program partners of the Upper Midwest Environmental Sciences Center. The data have been projected to UTM Zone 15, North American Datum 27 (NAD27), and the Clark 1866 ellipsoid. Most of the Missouri River levee data are not included in these files. If you require levee data for the Missouri River basin or would like to access or learn about the other SAST data sets, refer to the SAST home page.

background information Transportation (USGS-National Mapping Division)

USGS's 1:100,000-scale transportation data for the Upper Mississippi River floodplain are being redistributed through this web site as a service for program partners of the Upper Midwest Environmental Sciences Center. If you require these data as UNIX format files, data for additional areas, or want to make sure you have the most recent version of the data, contact the EROS Data Center. EROS makes these data available to download via the Internet.
