GENBKGRND: Seattle Roadway Channelization and Markings Data

Seattle's channelization data represents roadway paint lines, curbs, and other markings that delineate traffic lanes, bike routes, and bus zones. The dataset is owned by the SDOT Transportation account and was last updated on March 22, 2026. It is described as a dynamic layer updated via AutoCAD, with no scheduled refresh cycle.

Use Cases

• Model traffic lane configurations based on longitudinal and transverse markings data.
• Plan bicycle and bus route infrastructure based on delineated bike routes and bus zones.
• Analyze public safety infrastructure based on vertical elements and panel markings.
• Create base maps for urban planning based on the general background layer.

Strengths

• Data is described as dynamic, updated via AutoCAD, suggesting potential for current representations.
• Contains multiple structured layers including vertical elements, lane widths, and various marking types.
• Last update timestamp is provided (2026 03 22 03:38:18.403903).

Limitations

• Row count, column definitions, and sample data are unavailable, limiting suitability assessment.
• Description metadata is limited; actual data quality and schema require manual inspection after download.
• The 'None, Dynamic' refresh cycle description is ambiguous for understanding update frequency.
