ABSTRACT
The purpose of the Mississippi River map series is to provide reference for ecological vulnerability
throughout the entire Mississippi River Basin, which is a forthcoming product. The optional accompany-
ing plotted map series consists of seven 32 inch x 40 inch poster have a nominal scale of 1 inch = 3 miles.
The scale of these maps will vary with other plot sizes. Each map includes metadata, as follows:
(1)	Data type: Landsat ETM+ Panchromatic Band, 15 meter nominal spatial resolution
(2)	Imagery acquisition dates
(3)	Map projection: Universal Transverse Mercator, Zone 15
(4)	Imagery provided by: U.S. Environmental Protection Agency, a Multi-Resolution Land
Characteristics (MRLC) Consortium member
(5)	Constructed by: U.S. Environmental Protection Agency (C.M. Edmonds, R.D. Lopez, D.T. Heggem)
and U.S. Army Corps of Engineers (D.M. Williams and K.L. Short)
(6)	Map Version: 1.0
(7)	Map production date: August 5, 2003
The format of the map series is intended to allow for easy reference and includes basic reference
information so that further ecological vulnerability analyses can be conducted using existing water
quality data, existing hydrologic data, and land cover data. Reference data is overlaid on the map series,
as follows:
(a)	River mile locations at 25-mile intervals (source: U.S. Army Corps of Engineers, St. Louis District)
(b)	Lock and dam location (source: U.S. Army Corps of Engineers, St. Louis District)
(c)	City location with state abbreviation
(d)	Major Mississippi River tributaries
(e)	Floodway locations (source: U.S. Army Corps of Engineers, St. Louis District).
We optimized the number and size of the presentations to allow for sufficient detail in the images and
provide a hardcopy for reference as forthcoming additional ecological analyses are performed. The
miniature scale posters included on this CD are for quick reference. Forthcoming ecological analyses
include investigation of water quality or habitat vulnerability (after Lopez et. al, 2003). This map series
is an important first step toward developing a system-wide approach to understanding the functioning of
large rivers at a landscape scale. Note: Use the reference letters to connect segments of Landsat imagery.
