TIGER5---Extraction of geographic information from the TIGER system
The need for geographic information in digital form is becoming apparent in many areas, including Emergency Response Planning and Management. The Bureau of Census recognized this need and developed an automated geographic data base, known as Topologically Integrated Geographic Encoding and Referencing (TIGER) System, to produce the geographic products for the 1990 census. The Bureau makes the information available to the public on CD-ROM disks. As distributed, the geographic information is not directly visible, and a program is needed to display the information in a graphic form. MapInfo is a commercially available program that has the capability to display maps and allows the user to perform certain geographic analyses. MapInfo runs on a variety of low-cost platforms that may be found in an average office environment, as well as on high-performance work stations. The TIGER5 program developed by the Emergency Management Information Systems (EMIS) project at Oak Ridge National Laboratory reads files directly from the Census Bureau TIGER/Line CD-ROM and creates MapInfo Exchange Format Files that can be directly imported into MapInfo. The standard default values for scaling parameters are used, and the resulting map is in the same coordinate system as the world and state maps distributed with MapInfo.
