Oswego County Topological Face Polygons With Census Geocodes

U.S. Census Bureau provides a TIGER/Line shapefile of topological face polygons for Oswego County, NY. The data includes key geographic area codes used for building Census geographic area geometries. It is part of a seamless national system with no overlaps or gaps.

Use Cases

• Dissolve face geometries on County Fips Code to build county-level boundary maps for Oswego County.
• Analyze spatial relationships between Census Tract Number and Block Group using the topological face primitives.
• Join face attributes using the unique topological face identifier (TFID) to other Census demographic datasets.
• Build geometries for 5 digit zip code tabulation area code by dissolving face polygons on the appropriate ZCTA code.

Strengths

• Data originates from the authoritative U.S. Census Bureau Master Address File / TIGER System.
• Topological structure ensures a seamless national file with no overlaps or gaps between geographic parts.
• Each face includes key geographic area codes for all areas used in 2020 Census and annual surveys.

Limitations

• Specific row count, column count, and file size are unknown from the provided input.
• Data is limited to a single county (Oswego County, NY), requiring combination with other files for broader analysis.
• The description does not specify the coordinate reference system or spatial accuracy of the geometries.
