OS MasterMap Sites Layer: Key Infrastructure Access Points in Great Britain

The OS MasterMap Sites Layer provides a detailed view of the extents and access locations of important sites across Great Britain. It is produced by the Government Digital Service and includes polygon features for airports, schools, hospitals, and transportation terminals. The dataset is designed to help identify main points of access quickly in emergency situations and to reduce the impact of planned works on these key sites.

Use Cases

• Emergency response route planning based on documented access locations for key sites.
• Assessing the impact of construction or events on critical infrastructure based on site extents and access points.
• Mapping and analyzing the distribution of public service locations like schools and hospitals based on polygon features.
• Logistics planning for transportation networks using routing information for stations and terminals.

Strengths

• Focuses on key public infrastructure sites including schools, hospitals, and transportation hubs.
• Includes polygon features representing site extents along with name and routing information.
• Designed for practical applications in emergency response and planning.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
