2021 Armstrong County Texas Road Network Shapefile

2021 geographic data from the U.S. Census Bureau's TIGER/Line database provides a seamless, non-overlapping extract of all road and path features for Armstrong County, Texas. The shapefile includes primary roads, secondary roads, local streets, vehicular trails, ramps, alleys, bike paths, walkways, and other transportation features classified under the 'Road/Path Features' super class.

Use Cases

• Calculate road network density and connectivity metrics using the linear feature geometry for infrastructure planning.
• Geocode addresses by joining this street centerline data with address range information from related files.
• Analyze the distribution of road types (e.g., city streets vs. rural roads) using the MAF/TIGER Feature Classification Code (MTFCC).
• Integrate this county-level shapefile with others to build a seamless national road dataset for cross-regional routing analysis.

Strengths

• Data originates from the authoritative U.S. Census Bureau Master Address File/TIGER Database (MTDB), ensuring national consistency.
• The MTDB is designed as a seamless national file with no overlaps or gaps between geographic parts.
• Includes a comprehensive range of road and path types, from primary highways to bike paths and walkways.

Limitations

• The dataset is specific to a single county (Armstrong County, TX) and year (2021), limiting broader temporal or geographic analysis without combining other files.
• As a shapefile extract, it may require GIS software (e.g., QGIS, ArcGIS) or specialized libraries for full utilization, unlike simple tabular data.
