Aerial Photos (UMESC)

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.

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.

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).

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 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 on the file format/data transfer information page.

- 2000 Land Cover/Use (2.2 MB UNIX) (2.3 MB NT) (3.3 MB z15n27 Shape) (3.3 MB z15n83 Shape)

- 1989 Land Cover/Use version 2 (921 KB UNIX) (976 KB NT) (1.2 MB z15n83 Shape)

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.

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.
