Marseilles is used to describe the region of the Illinois River that is impounded by the Marseilles Lock and Dam. It extends from the Marseilles Lock located near Marseilles, Illinois, upstream to the Dresden Lock and Dam located south of Channahon, Illinois.
National Atlas and Seamless data server data have been moved to the National Map.
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.

2020 Systemic Imagery
The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020. The main purpose of the aerial imagery was to develop Land Cover/Land Use (LCU) spatial datasets of navigable pools (the stretch of river between locks and dams) and reaches of the UMRS

Lidar (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. These data are a product of the U.S. Army Corps of Engineers’ Upper Mississippi River Restoration (UMRR) Program Long Term Resource Monitoring (LTRM) element, as distributed by the U.S. Geological Survey, Upper Midwest Environmental Sciences Center, La Crosse, Wisconsin. Tier 1 products are derived directly from vendor-provided LAS-format (LASer) files that have not been cleaned or edited in order to serve the data as quickly as possible. Tier 1 data have been quality checked by the vendor and obvious errors removed, but some isolated errors often remain.

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.

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).

Since 1989 the Upper Midwest Environmental Sciences Center through its association with the Upper Mississippi River Restoration Programs Long Term Resource Monitoring element, has been creating land cover/use and other riverine datasets for the Upper Mississippi River System. For background information on how these data sets were created and are attributed, see the associated metadata in each geodatabase.
Topobathy
Separate Lidar and bathymetry data were collected on the Upper Mississippi River System (UMRS) by the US Army Corps of Engineers (USACE), Upper Mississippi River Restoration (UMRR) program. While many information needs can be met by using these data separately, in many cases seamless elevation data across the river and its floodplain are needed. This seamless elevation surface was generated by merging the Lidar and bathymetry data.

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.

Shape) 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.
