Description:
The SAST ARC/INFO database is a comprehensive vector basemap of the Upper
Mississippi/Missouri River Basin and contains attribute data suitable for
performing a wide range of analyses and for generating thematic maps for
counties and states throughout the flood area.
Abstract:
On January 10, 1994, the Scientific Assessment and Strategy Team (SAST)
joined in the effort to provide scientific advice and assistance to
officials responsible for making decisions with respect to the flood
recovery in the Upper Mississippi River Basin.
The SAST acquired from the Environmental Systems Research Institute (ESRI)
the ArcUSA 1:2,000,000-scale database via the medium Compact Disc-Read
Only Memory (CD-ROM). The ArcUSA database contains the USGS 1:2,000,000
County Boundaries layer in both Albers Conic Equal Area projection and in
geographic coordinates, outlines of the topographic maps quadrangle name,
USGS map reference code, map coverage by state for each quadrangle, and
the publication date.
Purpose:
The ArcUSA database provided the SAST with data formatted in the
Geographic Information System (GIS) ARC/INFO data model. The objectives
were to develop a database of readily available data to support map
production, scientific analysis, and decision making; to produce maps
showing base information and vulnerability to flooding; and to prepare
reports documenting the products of SAST and the methodology and
analysis used to produce them, and identifying the ongoing monitoring,
research, modeling, data management and distribution requirements needed
to support integrated river basin management.

SDTS_Terms_Description:
An area is a generic term for bounded, continuous, two-dimensional object
that may or may not include its boundary.
The attributes (or items) in the ARC/INFO feature attribute tables contain
different types of values; specifically, measurements, codes, flags, and names.
