Ordnance Survey: OGC Spatial Data Infrastructure Modernisation Project 2025 – 2026 


Ordnance Survey (OS) proposes to contribute content and examples highlighting real-world implementations that reflect the principles of a modern Spatial Data Infrastructure (SDI). Drawing on decades of experience in international SDI forums (e.g., UN-GGIM, INSPIRE), OS emphasizes the importance of improving data access, diversity, governance, and community engagement. This is illustrated through two flagship initiatives: the National Underground Asset Register (NUAR) and the OS Data Hub.

Key Features

  • Improved Data Access
    • NUAR: Secure access to underground infrastructure data across the UK.
    • OS Data Hub: API and web-based access to authoritative national geographic data.
  • More Diverse Data
    • NUAR: Includes gas, water, electric, telecom, and local authority assets.
    • OS Data Hub: Offers new thematic data (e.g., building materials, heights) and third-party data (e.g., BGS).
  • Open Data Standards
    • Both platforms use OGC standards (e.g., NGD APIs, MUDDI model).
  • Data Transformation and Interoperability
    • NUAR uses a harmonized data model derived from MUDDI. OS Data Hub supports both legacy and modern OGC APIs.
  • Efficient Governance Structures
    • Clear data stewardship roles (owners, custodians, stewards). Transparent data lifecycle management from collection to delivery.
  • Legal and Policy Frameworks
    • NUAR backed by the UK Data Bill (2025), with upcoming consultations on mandating participation. Flexible data sharing agreements for both platforms.
  • Public–Private Collaboration
    • 300+ signed data sharing agreements in NUAR. Broad engagement with both sectors to ensure trusted access.
  • Diverse Communities of Users and Providers
    • NUAR enables new use cases and stakeholders in safe excavation.
    • OS Data Hub has expanded reach to developers, SMEs, and researchers.
  • Training and Guidance
    • OS shares principles for successful data sharing initiatives and promotes skill development through its projects.

Benefits & Impact

  • Improved Infrastructure Safety and Efficiency
    • NUAR reduces excavation risks and project delays by consolidating buried asset data.
  • Scalable, Real-Time Data Access
    • Both platforms deliver up-to-date, mobile-friendly access to key infrastructure and mapping data.
  • Increased Participation and Interoperability
    • Demonstrates how public and private data can be harmonized and governed effectively in a federated SDI model.
  • Standards-Based Modernization
    • Advances adoption of OGC APIs and conceptual models, improving cross-border compatibility and future-proofing SDI services.
  • Model for Other Nations and Regions
    • Provides best practice examples in SDI design and implementation that can be adapted globally.

Use Cases

  • Infrastructure and utility management
  • Public access to authoritative data
  • Cross-sector data sharing
  • SDI governance modeling
  • Knowledge sharing and capacity building
