Shelby County Texas Road and Hydrography Linear Features 2023

2023 TIGER/Line shapefile from the U.S. Census Bureau containing linear geographic features for Shelby County, Texas. The dataset includes roads, railroads, and hydrography lines, with each edge identified by a unique TLID value. It is designed to be used independently or combined with other county files for national coverage.

Use Cases

• Analyze road network density and connectivity in Shelby County using the TLID-identified linear features.
• Map hydrography features like streams and rivers for environmental or land use planning in this Texas county.
• Integrate railroad line geometry with separate attribute files for transportation infrastructure analysis.
• Combine this county's All Lines Shapefile with others to build a seamless national linear feature dataset.

Strengths

• Data is topologically integrated with no overlaps or gaps, ensuring geometric consistency.
• Derived from the authoritative U.S. Census Bureau MAF/TIGER Database (MTDB).
• Each linear feature edge has a unique identifier (TLID) for precise referencing.

Limitations

• Critical attribute data for linear features is stored in separate relationship files that must be downloaded and joined.
