National Spatial Referencing Infrastructure
– Benefits & Opportunities
• Provides Ireland with a consistent authoritative spatial referencing system for
the integration and management of national spatial information.
– Common RW objects, unique ID’s referencing, consistent geographic positioning
• Prime2 is a foundation for a modern National Spatial Data Infrastructure.
• Provides users with high quality high intelligence reference data in an easy to
use industry standard data format.
• The standards based intelligent data storage model enables the generation of
products and services via data schemas designed for user requirements.
• The Prime2 data model enables INSPIRE Directive compliance.
• Provides solution developers and data integrators with a robust framework for
integrating 3rd party data.
• Enables OSi to develop enhanced Web Services (Web Feature Services)
