Cancer Alliances in England: Ultra Generalised Clipped Boundaries from February 2017

Five versions of digital vector boundaries for Cancer Alliances in England as of February 2017, ranging from full resolution to ultra generalised (500m). The dataset contains Ordnance Survey and Office for National Statistics intellectual property rights and is provided by the Office for National Statistics. File sizes for the different boundary versions range from 71 KB for the ultra generalised version to 15 MB for the full resolution version clipped to the coastline.

Use Cases

• Map Cancer Alliance administrative regions for health service planning based on the provided vector boundaries.
• Perform spatial joins with health outcome data using the ultra generalised (500m) boundaries for simplified analysis.
• Visualise regional cancer service structures in England based on the February 2017 snapshot.
• Compare different boundary generalisation levels (20m, 200m, 500m) for cartographic or computational efficiency.

Strengths

• Provides five distinct boundary versions with specific file sizes, such as a 71 KB ultra generalised version for lightweight use.
• Includes direct REST service URLs for programmatic access and download.
• Contains boundaries clipped to the Mean High Water mark, offering a consistent coastal definition.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data is from a single snapshot in February 2017; temporal coverage is limited.
• Row count is unknown, which may limit suitability assessment for large-scale statistical joins.
