TIGER/Line Shapefile, 2019, Series Information for the Area Landmark State-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.
The Census Bureau includes landmarks in the MTDB for locating special features and to help
enumerators during field operations. Some of the more common landmark types include area landmarks
such as airports, cemeteries, parks, schools, and churches and other religious institutions. The
Census Bureau added landmark features to MTDB on an as-needed basis and made no attempt to ensure
that all instances of a particular feature were included. The presence or absence of a landmark
such as a hospital or prison does not mean that the living quarters associated with that landmark
were geocoded to that census tabulation block or excluded from the census enumeration. The Area
Landmark Shapefile does not include military installations or water bodies because they each appear
in their own separate shapefiles, MIL.shp and AREAWATER.shp respectively.
