Tattnall County GA Topological Faces with Geocodes 2022

U.S. Census Bureau provides topological face polygons for Tattnall County, Georgia, from the 2022 TIGER/Line database. These faces are the areal primitives used to build all Census geographic areas, each containing key geographic area codes for data tabulation. The dataset is part of a seamless national file designed to stand alone or be combined for national coverage.

Use Cases

• Dissolve face geometries on the County Fips Code to reconstruct the county boundary polygon.
• Build Census Tract geometries by dissolving face polygons on the Census Tract Number attribute.
• Analyze the spatial composition of Block Groups by aggregating faces using the Block Group code.
• Create a map of 5 digit zip code tabulation area code boundaries by dissolving the topological faces.

Strengths

• Data originates from the authoritative U.S. Census Bureau Master Address File/TIGER Database.
• Each topological face has a unique identifier (TFID) and contains codes for all Census geographic areas.
• The dataset is part of a seamless national file with no overlaps or gaps between parts.

Limitations

• Data is specific to a single county (Tattnall County, GA) and year (2022), limiting broader temporal or geographic analysis without combining other files.
• The exact row count, column count, and file size are unknown, making it difficult to assess the dataset's scale and structure prior to download.
