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.
A coverage locating wildlife habitats was developed from resource provided
to the SAST from the Environmental Management Technical Center/National
Biological Survey. Important wildlife habitats are defined as areas which
provide suitable areas for wildlife propagation, feeding, and resting.
These areas typically are backwaters, side channels, islands, and large
expanses of open water and forested floodplain that offer diversity
required for sustaining wildlife populations. Also included were popular
trapping and hunting areas and state and federal wildlife areas and
refuges. Data were compiled by state and federal wildlife biologists who
were familiar with the resources in their area.
The wildlife habitat data were developed by the USFWS for the U.S. Army
Corp of Engineers(USACE) as part of the Resource Inventory for the Upper
Mississippi River of GREAT II (Great River Environmental Action Team)
in the early 1980's. The habitat areas were were mapped on Navigation
charts created by the USACE.
The data were automated at EROS Data Center using on-screen digitizing
creating an ARC/INFO coverage, WILDLIFE.
Purpose:
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 document-
ing 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.
Supplemental_Information:
In ARC/INFO the Copy command was used to off-load individual coverages
together with their associated INFO files.
ARC is the main program environment in ARC/INFO. It contains commands
which start each of the other subsystems and also has extensive
capabilities.
INFO is a complete relational database manager for the tabular data
associated with geographic features in map coverages. It provides
facilities for data definition of new data files, use of existing data
files, data entry and update, and sort and query.
ARC/INFO keeps track of and updates map feature attribute tables which are
stored as INFO files. It maintains the relationships between each map
feature and a corresponding tabular record.
ARCPLOT is the interactive cartographic and mapping subsystem of ARC/INFO.

Cross_Reference:
Upper Mississippi/Missouri River Basin ARC/INFO coverages in the Scientific
Assessment and Strategy Team (SAST) database.
During ARC/INFO coverage development several modifications were made to the
source data in order to generate a database with a common scale, uniform level
of resolution, consistent coding scheme, and comparable (standardized)
measurement data.
Attribute_Accuracy:
Attribute_Accuracy_Report:
Use frequency analysis to identify coding errors. Manual comparison of
the source (USACE Navigation charts) with hard copy plots using the
ARCPLOT software in the ARC/INFO data model.
Attribute_Accuracy_Value:
The accuracy of most attributes has not been explicitly tested against
independent sources. However, all the data derived from the USFWS
database have been reviewed for anomalous visual patterns both on line
and in hard copy.
Logical_Consistency_Report:
All data were found to be topologically correct. No duplicate features
are present. All lines intersect where intended. No undershoots or
overshoots are present. Polygon and arc-node topology present.
Completeness_Report:
Data completeness reflects the content of the source, "Resource
Inventory, Upper Mississippi River" from which the polygons were
retrieved. Features may be eliminated, misaligned, or generalized
on the source graphic, due to scale and legibility constraints.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal positional accuracy is based upon the placement of the
data from the USFWS source(Resources Inventory Upper Mississippi River,
1984) onto the Digital Line Graphs from 1:100,000-scale maps. The ARC
Tolerance command is used to set and examine the tolerances associated
with the DLG data set. Positional accuracy between the DLG data set
and ARC data file is indicated as 1.0 inch. Features were digitized by
visual interpretation from the operator.

Process_Step:
Process_Description:
The wildlife data were automated at the EROS Data Center. A projected
tic file was created from indexalb. Indexalb is a tic file consisting
of 27,000 tics at 7.5 minute intervals covering the complete study area
used as a base tic file. Wildlife polygons were extracted from the
Resources Inventory Map series by on-screen digitizing. Using
background covers of the DLG 1:100,000 hydrology, roads, and railways,
and the river mileage, spatial placement of the polygons was
determined. The wildlife areas were captured by following the
shoreline of the river on the DLG's and operator visual interpretation
of the source data. The interior islands were digitized as background.
Upon completion of digitizing, the coverage was cleaned and a create
label was performed. A LABEL and a NAME item was added. Visual
verification of the data was done to check for polygon slivers and
interior islands to be attributed.
NOTE:
Visual interpretation of the data was complicated by the overlapping
of the categories. For instance, the sport fishing was bars along the
side of each other, the commercial fishing was open squares, and the
spawning areas were dots about a half millimeter apart. Areas with
all three categories present with boundary lines became illegible.
This was further complicated with half the Resource Inventory maps
being black and white photo copies, instead of original data. The
photo copies lacked the color code of the original leaving overlapped
categories a black mass. This left the operator to make judgement
calls on the category in the specific area being digitized. Also, the
1:100,000 river coverage was not always consistent with the source
data. The inconsistency of the two sources left a great deal of
visual interpretation of the polygon boundaries up to the operator.
Create coverage topology and feature attribute tables for the new
coverage using ARC commands BUILD and CLEAN:
BUILD creates or updates a feature attribute table for a
coverage. It defines polygon and arc-node topology when
the POLY option is used.
CLEAN generates a coverage with correct polygon or arc-node
topology. It edits and corrects geometric coordinate
errors, assembles arcs into polygons, and creates
feature attribute information for each polygon
(i.e. creates a .PAT).

Overview_Description:
Entity_and_Attribute_Overview:
A coverage contains both the locational data and thematic attributes
associated with map features. In a coverage, map features are stored
as points, lines (arcs), or polygons. Points represent features like
named places. They have no length and are defined as a single x,y
coordinate pair. Lines represent linear features like railroads.
Lines have length but no area (polygon) and are defined as a string of
x,y coordinate pairs with beginning and ending points. Polygons
represent features like counties or lakes and are defined as a
string of x,y coordinate pairs with the same beginning and ending
points. These attributes are stored in Feature Attribute Tables. Each
feature class in a coverage has its own table: line attributes are
stored in Arc Attribute Tables (AATs); polygon attributes are stored in
Polygon Attribute Tables (PATs); and point attributes are stored
in Point Attribute Tables (PATs).
ARC/INFO-"generated attributes" are automatically created and are
different for each coverage. The feature attribute table contain
information about and values for a particular record. An INFO table
specifies the format for each record in the data file and is referred
to as the Items Definition. Items are defined by their name, the data
type, the number of characters used to store values, a display width,
and (for decimal numbers) the number of decimals to display.
