Published by U.S. Department of Commerce, U.S. Census Bureau, Geography Division, Spatial Data Collection and Products Branch | U.S. Census Bureau, Department of Commerce | Catalog Last Checked: May 05, 2026 at 11:02 PM | Dataset Last Updated: January 01, 2018 at 12:00 AM
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. Linear Water Features includes single-line drainage water features and artificial path features that run through double-line drainage features such as rivers and streams, and serve as a linear representation of these features. The artificial path features may correspond to those in the USGS National Hydrographic Dataset (NHD). However, in many cases the features do not match NHD equivalent feature and will not carry the NHD metadata codes. These features have a MAF/TIGER Feature Classification Code (MTFCC) beginning with an "H" to indicate the super class of Hydrographic Features.
