Europe & Global

The vision of p2d2 is a worldwide, federated Spatial Data Infrastructure for open data.

Europe

INSPIRE as Foundation

p2d2 builds on INSPIRE:

• Interoperability: Harmonized data models
• Services: View, Download, Discovery
• Metadata: ISO 19115/19119

Pilot Countries

Netherlands

• Strong OpenData culture
• Very active OSM community
• data.overheid.nl as central portal

France

• data.gouv.fr as OpenData portal
• Cooperation with OpenStreetMap France

Poland

• Growing OpenData movement
• EU funding available

Multilingualism

UI Translation

// i18n-Config
const translations = {
  de: {
    'feature.create': 'Feature erstellen',
    'qc.submit': 'Zur QS einreichen'
  },
  en: {
    'feature.create': 'Create feature',
    'qc.submit': 'Submit for QC'
  },
  fr: {
    'feature.create': 'Créer une entité',
    'qc.submit': 'Soumettre au contrôle qualité'
  }
};

Data Multilingualism

{
  "type": "Feature",
  "properties": {
    "name": {
      "de": "Kölner Dom",
      "en": "Cologne Cathedral",
      "fr": "Cathédrale de Cologne"
    }
  }
}

Federated Architecture

Instance Directory

# registry.yml
instances:
  - id: de-nrw-cologne
    url: https://cologne.data-dna.eu
    language: de
    country: DE
    state: NRW
  
  - id: nl-amsterdam
    url: https://amsterdam.data-dna.eu
    language: nl
    country: NL

Cross-Instance Queries

User in Aachen searches for cemeteries within 50km radius
→ Query to de-nrw-aachen
→ Recognizes: 50km reaches into NL
→ Federated query to nl-maastricht
→ Merge results

Global Scaling

Developing Countries

p2d2 can particularly help in countries with weak SDI infrastructure:

• Low entry barriers: Only browser and internet needed
• Community-driven: Local knowledge is utilized
• Open Source: No license costs

Disaster Response

After natural disasters:

• Rapid mapping: Record damaged infrastructure
• Coordination: Aid organizations use common data basis
• HOT: Integration with Humanitarian OpenStreetMap Team

Technical Challenges

Performance

• Tile caching: Globally distributed CDNs
• Database sharding: Geographic distribution
• API rate limiting: Protection against overload

Data Sovereignty

• National sovereignty: Each country controls its data
• GDPR: European data protection regulations
• Local laws: Country-specific requirements

Partnerships

OpenStreetMap Foundation

• Data exchange: Bidirectional synchronization
• Community: Joint events and mapathons

WikiData

• Linked Open Data: Linking with WikiData items
• Multilingualism: Use of WikiData labels

OGC (Open Geospatial Consortium)

• Standards: Participation in OGC standards
• Certification: OGC-compliant implementation

By 2030:

• 10,000+ municipalities worldwide
• 1,000,000+ users
• 100,000,000+ features recorded

Think Global, Act Local

Global infrastructure, local data, community-driven.
