TIGER/Line Shapefile, 2016, Series Information for the Area Hydrography 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 File is designed to stand
alone as an independent data set, or they can be combined to cover the entire nation. The Area Hydrography Shapefile contains the
geometry and attributes of both perennial and intermittent area hydrography features, including ponds, lakes, oceans, swamps (up to the
U.S. nautical three-mile limit), glaciers, and the area covered by large rivers, streams, and/or canals that are represented as
double-line drainage. Single-line drainage water features can be found in the Linear Hydrography Shapefile (LINEARWATER.shp). Linear
water features includes single-line drainage water features and artificial path features, where they exist, that run through
double-line drainage features such as rivers, streams, and/or canals, and serve as a linear representation of these features.
