2. Supra-National Geo Collaboration

Geospatial data exchange across country borders

Need for Supra-National Data Sharing

• Natural disasters and as well as other environmental phenomena (e.g. earth quakes, river pollution, forest fires, smog) do not stop at national borders

• 20% of the EU citizens (115 million) live within 50 Km from a border

• 70% of all fresh water bodies in Europe are part of a transboundary river basin

Need for Supra-National Data Sharing

• Cross boundary transporta-tion networks (road, rail, rivers, air) need to be aligned

• Cross border geology Oil and Gas fields (exploration and production) and Water Aquifers

Need for Supra-National Data Sharing

• High quality data is needed for cross-border decision making and sustainable development across countries

• Data needs to be uniform across countries for comparison

Supra-National Data Issues

1. Data is NOT SHARED between countries• Islands of Information

2. QUALITY OF DATA differs across countries (not uniform)• Different semantic definitions (meaning) of objects

• Different attribute and domain value definitions

• Differences in data capture (scales, level of detail, method)

• Geometries not match at borders (edge matching problems)

• Cartographic differences (styles, symbols)

Example – Administrative Units

• Edge Matching problems due to different data definitions and capture rules

Example – Transport Networks

• Differences in level of detail and edge matching issues

Example – Protected Sites

• Differences in cartographic representations

Example – Elevation

• Different geodetic datums (hor. + vert.) used by countries

3. Best Practice EU INSPIRE (Supra-National SDI)

INfrastructure for SPatial InfoRmation in Europe

Goals of INSPIRE

1. Make data of countries discoverable (catalog)

2. Share data between countries (web services)

3. Harmonize geodetic reference frames between countries

4. Harmonize data models between countries

EU INSPIRE Directive

• Directive 2007/2/EC of the EU Parliament and of the Council of 14 March 2007 establishing an INfrastructure for SPatial InfoRmation in Europe

• Scheduled to be completed in 2021

INSPIRE Architecture

• Reference document register• Theme register• Layer register• Application schema register • Code list register• Metadata code list register• Enumeration register• Feature concept dictionary• Media-types register• Glossary

Service Oriented (Publish-Find-Bind)

• Currently many countries only share data through geoportals Barrier for System to System exchange of geospatial information

• INSPIRE Create a services catalog and disseminate geospatial data As-A-Service

• Quality of Service of INSPIRE web services very well defined

Roadmap AS Geoportal implemenation

# Steps Responsible

1a DESIGN a (web service oriented) AS Geoportal Tunesia

1b Each country provides 1-3 DATASETS (e.g. Highways, Provinces, Geonames) as a VIEW service (WMS) + decribed with metadata in a CATALOG service (CSW)

All Arab States Countries

2a Develop Service Oriented Arab States Geoportal Tunesia

2b Host Operational Arab States Secure Geoportal Saudi Arabia

3a Connect the VIEW service and CATALOG of each country to the AS Geoportal Tunesia + Saudi Arabia

3b Maintain Content of the Arab States Secure Geoportal (update the dataset) All Arab States Countries

4 Each country provides 1 dataset as download service (e.g. country border) All Arab States Countries

5 Repeat for other Fundamental Datasets

6. Conclusions

Conclusions1. Don’t forget the WHY of supranational collaboration Cross-Border use cases

and being able to compare and aggregate data across countries

2. Current problemsa. Data is NOT SHARED between countriesb. QUALITY OF DATA differs across countries (not uniform)

3. Make country data discoverable through METADATA CATALOG SERVICES

4. Make country data directly accessible as GEOSPATIAL DATA SERVICES

5. Analyze geodetic differences between countries HARMONIZE geodetic reference models

6. Analyze data differences between countries HARMONIZE data models + cartographic visualizations

7. INSPIRE provides best practices for Arab States' supra-national data sharing initiative(s)

8. Integrate data from AS NSDI’s in the Arab States Geoportal using web services

9. Use International Geospatial Standards (W3C|ISO|OGC|HSO) for web services interoperability
