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 Topological Faces / Military Installation Relationship File (FACESMIL.dbf) contains a record for each face / military installation
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 / Military Installation Relationship File (FACESMIL.dbf) applies can be determined
by linking to the Topological Faces Shapefile (FACES.shp) on the permanent topological face identifier (TFID) attribute. The military
installation to which a record in the Topological Faces / Military Installation Relationship File (FACESMIL.dbf) applies can be
determined by linking to the Military Installation Shapefile (MIL.shp) on the military installation identifier (AREAID) attribute. A
face may be part of multiple military installations. A military installation may consist of multiple faces.
