ARC/INFO coverage of the points representing the Upper Mississippi/Missouri River Basin biological habitat for birds Citation_Information: Originator: Scientific Assessment and Strategy Team (SAST) Publication_Date: 19950526 Title: BIRDS ARC/INFO Coverage Geospatial_Data_Presentation_Form: map Online_Linkage: http://edcwww.cr.usgs.gov/sast-home.html 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 birds data set was developed from resources provided to the SAST from the Environmental Management Technical Center/National Biological Survey. Data was combined to create a point coverage showing rookeries for herons, cormorants, and egrets, as well as important eagle use areas. These data include information that was compiled by state and federal wildlife biologists who were familiar with the resources in their area. The eagle use and rookeries data were developed by the USFWS for the U.S. Army Corp of Engineers 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 data were automated at EROS Data Center using on-screen digitizing creating an ARC/INFO coverage, called BIRDS. 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. Spatial_Domain: Bounding_Coordinates: Geographic coordinates (latitude/longitude) in decimal degrees.

Data_Quality_Information:

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. Completeness_Report: Data completeness reflects the content of the source, "Resource Inventory, Upper Mississippi River" from which the data points 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 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 a 64.023 tolerance, however this value is non-verified. Features were digitized by visual interpretation from the operator. Lineage: Source_Information: Resources Inventory for the Upper Mississippi River, 1984.

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. The points for the coverage were capture 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 points was determined. The eagle symbols were captured as points by following the shoreline of the river on the DLG's and operator visual interpretation of the source data. Create coverage topology and feature attribute tables for the new coverage using ARC command BUILD : BUILD creates or updates a feature attribute table for a coverage. Point features and their attributes are created with the POINT option.

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.
