TIGER/Line Shapefile, 2016, Series Information for the Topological Faces-Area Landmark State-based Relationship File

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 Topological Faces / Area Landmark Relationship File (FACESAL.dbf) contains a record for each face / area landmark relationship.
                             Face refers to the areal (polygon) topological primitives that make up MTDB.  A face is bounded by one or more edges; its boundary
                             includes only the edges that separate it from other faces, not any interior edges contained within the area of the face.  The face to
                             which a record in the Topological Faces / Area Landmark Relationship File (FACESAL.dbf) applies can be determined by linking to the
                             Topological Faces Shapefile (FACES.shp) on the permanent topological face identifier (TFID) attribute.  The area landmark to which a
                             record in the Topological Faces / Area Landmark Relationship File (FACESAL.dbf) applies can be determined by linking to the Area
                             Landmark Shapefile (AREALM.shp) on the area landmark identifier (AREAID) attribute.  A face may be part of multiple area landmarks.
                             An area landmark may consist of multiple faces.
