Seattle's Department of Transportation (SDOT) provides a geospatial data model linking street use permits to impacted street segments. The dataset is derived from dissolving line segments by permit number to show all impacts for a given permit, while maintaining relationships to drill down to specific segments. The data is updated nightly and is constructed for use in the Right of Way Map.
Use Cases
- Visualize all street segments impacted by a specific permit based on the permit-to-impact relationship.
- Analyze spatial patterns of street use permit impacts across Seattle based on the geospatial line segments.
- Drill down from a permit's aggregated impacts to inspect specific use impact segments based on the hierarchical data model.
- Integrate permit impact data into a Right of Way mapping application based on the service construction description.
Strengths
- Data model explicitly defines relationships between permits and impacted street segments, enabling hierarchical analysis.
- Dataset is updated nightly, suggesting regular maintenance.
- Service is constructed for a specific application (Right of Way Map), indicating practical utility.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
