2. . Supra-National Geo Coll llaboration Geospatial data exchange across country borders
Need for Supra-National Data Sharing • Natural disasters and as well as • 70% of all fresh water bodies in other environmental phenomena Europe are part of a (e.g. earth quakes, river transboundary river basin pollution, forest fires, smog) do not stop at national borders • 20% of the EU citizens (115 million) live within 50 Km from a border
Need for Supra-National Data Sharing • Cross boundary transporta- • Cross border geology Oil and tion networks (road, rail, Gas fields (exploration and rivers, air) need to be production) and Water Aquifers aligned
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
. Best Practice EU IN 3. INSPIRE (S (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
Service Levels (QoS) • Quality of Service of INSPIRE web services very well defined

UN GGIM Arab States Members
Arab States Geo Collaboration Examples of Geo Collaboration between countries 1. Cross-border applications 2. National applications that use data from other country/countries 3.

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 All Arab States VIEW service (WMS) + decribed with metadata in a CATALOG service (CSW) 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
Conclusions Don’t forget the WHY of supranational collaboration Cross-Border use cases 1. and being able to compare and aggregate data across countries 2. Current problems a. Data is NOT SHARED between countries b. 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 Analyze geodetic differences between countries HARMONIZE geodetic 5. reference models Analyze data differences between countries HARMONIZE data models + 6. 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
