TIGER/Line Shapefile, 2012, county, St. Martin Parish, LA, Current Area Hydrography Shapefile
Dataset Identification:
Resource Abstract:
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. 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.

ConceptualConsistency
measure Description
The Census Bureau performed automated tests to ensure logical consistency and limits of shapefiles. Segments making up the
outer and inner boundaries of a polygon tie end-to-end to completely enclose the area. All polygons are tested for closure.
The Census Bureau uses its internally developed geographic update system to enhance and modify spatial and attribute data
in the Census MAF/TIGER database. Standard geographic codes, such as FIPS codes for states, counties, municipalities, county
subdivisions, places, American Indian/Alaska Native/Native Hawaiian areas, and congressional districts are used when encoding
spatial entities. The Census Bureau performed spatial data tests for logical consistency of the codes during the compilation
of the original Census MAF/TIGER database files. Most of the codes for geographic entities except states, counties, urban
areas, Core Based Statistical Areas (CBSAs), American Indian Areas (AIAs), and congressional districts were provided to the
Census Bureau by the USGS, the agency responsible for maintaining FIPS 55. Feature attribute information has been examined
but has not been fully tested for consistency. For the TIGER/Line Shapefiles, the Point and Vector Object Count for the G-polygon
SDTS Point and Vector Object Type reflects the number of records in the shapefile attribute table. For multi-polygon features,
only one attribute record exists for each multi-polygon rather than one attribute record per individual G-polygon component
of the multi-polygon feature. TIGER/Line Shapefile multi-polygons are an exception to the G-polygon object type classification.
Therefore, when multi-polygons exist in a shapefile, the object count will be less than the actual number of G-polygons.
