Houston County TX Topological Faces with Census Geocodes

Topological polygon data for Houston County, Texas, extracted from the U.S. Census Bureau's 2023 TIGER/Line database. It contains face primitives with unique identifiers and key geographic area codes for Census tabulation. The data is designed to be combined with other shapefiles to create seamless national coverage.

Use Cases

• Dissolve face geometries on key geographic area codes like Census Tract Number or Block Group to build geometries for specific administrative boundaries.
• Analyze spatial relationships between topological faces and their attributes, such as County Fips Code or Congressional District Code, for demographic mapping.
• Integrate the Topological Faces Shapefile with other TIGER/Line extracts using the unique topological face identifier (TFID) to create a comprehensive national geographic database.

Strengths

• Data originates from the authoritative U.S. Census Bureau Master Address File / TIGER Database (MTDB), ensuring national consistency.
• Each topological face includes key geographic area codes for all geographic areas tabulated in the 2020 Census and subsequent surveys.
• The shapefile is part of the 2023 TIGER/Line series, providing recent geographic boundaries and codes.

Limitations

• The dataset is limited to Houston County, Texas, requiring combination with other county files for broader regional or national analysis.
• Specific metrics like row count, file size, and column details are unavailable, complicating assessment of data volume and structure.
