TIGER/Line Shapefile, 2019, Series Information for the All Lines County-based Shapefile
Description
The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected
geographic and cartographic information from the U.S. Census Bureau's Master
Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database
(MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts,
however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they
can be combined to cover the entire nation.
Edge refers to the linear topological primitives that make up MTDB. The All Lines Shapefile contains
linear features such as roads, railroads, and hydrography. Additional attribute data associated with
the linear features found in the All Lines Shapefile are available in relationship (.dbf) files that
users must download separately. The All Lines Shapefile contains the geometry and attributes of each
topological primitive edge. Each edge has a unique TIGER/Line identifier (TLID) value.
