Description:
Abstract: CUGIR, The Cornell University Geospatial Information Repository, using US Department of Commerce, Bureau of the Census data, developed the GIS data set versions of 1990 Census TIGER/Line files for 5 coverages for each of the 62 counties in New York State.
Purpose: These files were developed to enable a user to see the geographic component from 1990 TIGER/Line Census files. They can be used to join demographic data for use in conjunction with other Census data in geographic and demographic analysis.
Supplemental_Information: To find out more about TIGER/Line files and other Census TIGER data base derived data sets visit "TIGERĀ®, TIGER/LineĀ® and TIGER-Related Products" of the Census Bureau at: <https://www.census.gov/geo/maps-data/data/tiger.html>.

Data_Quality_Information

Attribute_Accuracy:
Attribute_Accuracy_Report: Original TIGER/Line data is accurate against Federal Processing Standards (FIPS), FIPS Publication 6-4 and FIPS-55 at the 100% level for the codes and base names. The remaining attribute information has been examined but has not been fully tested for accuracy. The digital files fro the Census Bureau were converted into shapefiles. The attributes supllied in the TIGER files have not been changed by CUGIR. Refer to "Chapter 5" and "Chapter 6" in the U.S. Census Bureau TIGER/Line file Technical Documentation, available at <https://assets.nhgis.org/original-data/gis/TIGER_1992_TechDoc.pdf>
Logical_Consistency_Report: According to TIGER/Line documentation: the feature network of lines (as represented by Record Types 1 and 2) is complete for census purposes. Spatial objects in TIGER/Line belong to the "Geometry and Topology" (GT) class of objects in the "Spatial Data Transfer Standard" (SDTS) FIPS publication 173 and are topologically valid. Node/geometry and topology (GT)-polygon/chain relationships are collected or generated to satisfy topological edit requirements. These requirements include: -Complete chains must begin and end at nodes; -Complete chains must connect to each other at nodes, -Complete chains do not extend through nodes; -Left and right GT-polygons are defined for each complete chain element and are consistent throughout the extract process; -The chains representing the limits of the files are free of gaps. The Census Bureau performed automated tests to ensure logical consistency and limits of files. All polygons are tested for closure.
Completeness_Report: Data completeness of the TIGER/Line files reflects the contents of the Census TIGER data base at the time the TIGER/Line files (1990 version) were created.1990 Census TIGER/Line files are primarily based on the USGS 1:1000,000 scale Digital Line Graph files. Refer to the Technical documentation for features that are not present.

Process_Step:
Process_Description: In order for others to use the information in the Census TIGER data base in a GIS or for other geographic applications, the Census Bureau releases periodic extracts of selected information from the Census TIGER data base, organized as topologically consistent networks. Software (TIGER DB routines) written by the Geography Division allows for efficient access to Census TIGER system data. TIGER/Line files are extracted from the Census TIGER data base by county or statistical equivalent area. Census TIGER data for a given county or statistical equivalent area is then distributed among 17 fixed length record ASCII files, each one containing attributes for either line, polygon, or landmark geographic data types. The Bureau of the Census has released various versions of the TIGER/Line files since 1988, with each version having more updates (feature and feature names, address ranges and ZIP Codes, coordinate updates, revised field definitions, etc.) than the previous version. Information concerning steps taken to create TIGER/Line is available in "Chapter 5: Data Quality" in TIGER/Line Documentation, available at <https://assets.nhgis.org/original-data/gis/TIGER_1992_TechDoc.pdf>.

Process_Date: 1990
Process_Step:
Process_Description: The 1990 TIGER shapefiles were downloaded originally from the Geography Network <http://www.geographynetwork.com>. Each Census hierarchical level (County, Tract, Block Group, and Block) was joined to it's associated SF1 demographics database table, also downloaded from the Geography Network. A VBA script was written within ArcGIS 8.2 (ArcInfo) to automate the process of joining each county level file with its demographic table, and then exporting with unique file names. This process was done 4 times, one for each of the Census geographies. For the remaining TIGER data, (all but the boundary files) all files were originally downloaded from Geography Network, renamed and added to CUGIR with no further processing.

Entity_and_Attribute_Information

Overview_Description:
Entity_and_Attribute_Overview: The TIGER/Line files contain data describing three major types of features/entities; Line Features: 1) Roads; 2) Railroads; 3) Hydrography; 4) Miscellaneous transportation features and Selected power lines and pipe lines; 5) Political and statistical boundaries. Landmark Features: 1) Point landmarks, e.g., schools and churches; 2) Area landmarks, e.g., Parks and cemeteries; 3) Key geographic locations (KGLs), e.g., apartment buildings and factories. Polygon features: 1) Geographic entity codes for areas used to tabulate the 1990 census statistical data and current geographic areas; 2) Locations of area landmarks 3) Locations of KGLs. The line features and polygon information form the majority of data in the TIGER/Line files. Some of the data/attributes describing the lines include coordinates, feature identifiers (names), CFCCs (used to identify the most noticeable characteristic of a feature), address ranges, and geographic entity codes. The TIGER/Line files contain point and area labels that describe landmark features and provide locational reference. Area landmarks consist of a feature name or label and feature type assigned to a polygon or group of polygons. Landmarks may overlap or refer to the same set of polygons. The Census TIGER data base uses collections of spatial objects (points, lines, and polygons) to model or describe real-world geography. The Census Bureau uses these spatial objects to represent features such as streets, rivers, and political boundaries and assigns

The TIGER/Line documentation defines the terms and definitions used within the files.
