UK Travel to Work Areas Super Generalised Boundaries from December 2011

Five vector boundary files for UK Travel to Work Areas as of December 2011, provided by the Office for National Statistics. The dataset includes full-resolution, generalised (20m), super generalised (200m), and ultra generalised (500m) versions, each clipped to the Mean High Water coastline. File sizes range from 382 KB for the ultra generalised version to 68 MB for the full-resolution clipped version.

Use Cases

• Map commuting zones based on the super generalised (200m) boundaries for national-level analysis.
• Integrate boundary data into GIS software using the provided ArcGIS REST feature service URLs.
• Perform spatial joins with census data using the December 2011 TTWA geography.

Strengths

• Provides five distinct boundary generalisation levels, from full resolution (68 MB) to ultra generalised (382 KB).
• Contains intellectual property rights from both Ordnance Survey and the ONS.
• Offers multiple access methods including direct file download and ArcGIS REST services.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data reflects a specific snapshot from December 2011 and may not reflect current boundaries.
