The Census TIGER/Line files are, in total, an extract of selected geographic and cartographic information from the Census Bureau's TIGER (Topologically Integrated Geographic Encoding and Preferencing) database. The TIGER/Line files are a digital database of geographic features, such as roads, railroads, rivers, lakes, legal boundaries, census statistical boundaries, etc. covering the entire United States. These files contain information about these features such as their location in latitude and longitude, the name, the type of feature, address ranges for most streets, the geographic relationship to other features, and other related information. These files are not graphic images of maps, but rather digital data describing geographic elements found in every county and statistically equivalent entity. To make use of these data, a user must have mapping or Geographic Information System (GIS) software that can import TIGER/Line data.
