Topological Faces polygons from the U.S. Census Bureau's TIGER/Line database for Pope County, Illinois, containing all geographic area codes used for 2020 Census tabulation. Each polygon face has a unique topological face identifier (TFID). The data is designed to stand alone or be combined with other counties to create a seamless national file.

Use Cases

• Dissolve face geometries on key geographic area codes like County Fips Code or Census Tract Number to build the boundaries of specific administrative units.
• Analyze spatial relationships between faces using the unique topological face identifier (TFID) to understand adjacency and contiguity.

Limitations
