A geospatial dataset from the City of Seattle, last updated March 2026, representing the city's transportation network as linear segments and intersections. It includes features such as Freeways, Highways, Streets, Alleys, Railroads, Walkways, and Bike lanes, with attributes for street names, address ranges, and segment characteristics. The data serves as the city's official address range repository and defines topological connections between network features.
Use Cases
- Cartography and map labeling based on street names and address ranges.
- Address validation and geocoding reference based on the address range repository.
- Network route tracing and pathfinding based on topological segment connections.
- Associating thematic data to specific streets or intersections based on unique, stable identifiers.
- Defining polygon boundaries for other feature classes based on coincident transportation network lines.
Strengths
- Includes multiple segment types: Freeways, Highways, Streets, Alleys, Railroads, Walkways, and Bike lanes.
- Provides unique, stable identifiers for each linear and intersection feature for data association.
- Serves as the City of Seattle's official address range repository.
- Available in multiple file formats including CSV, JSON, KML, and GeoPackage.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
- The description states it does not contain polygon features, limiting certain spatial analyses.
