3 The GeoShare Project  Collaboration of 4 partners in the North Sea Region Sogn og Fjordane (Norway) Groningen (Netherlands) Edinburgh (Scotland) Bremen (Germany)  Mostly administration, plus technical experts  Project is funded through the EU Interreg IIIB North Sea Region programme  Duration: 12/02 – 12/05

4 Objectives  Improve exchange and usage of geospatial data and other spatially related information  Establish a transnational cooperation in 3 thematic areas: Spatial planning Labour and education Tourism and cultural heritage  Develop a transnational (technical) infrastructure for the exchange of geospatial data and information

5 Technical Approach to GeoShare  The GeoShare Network is a transnational, OGC compatible and service- based geodata infrastructure  Distributed services, accessible to all project partners  Concept is tested and proven (e.g., GDI-NRW)  Two types of services: Basic services (basic functionality needed by all partners) Advanced services (specialized functionality needed by one or more regional applications)

6 GeoShare Network: Implementation-Phase I  Intelligent Catalog Service (ICS) provides centralized registration, search, and metadata management services  Applications in the partner regions remain independent  Applications are hosted and maintained by the partners  Applications are accessible through customized clients

7 GeoShare Network: Implementation-Phase II  A common WMS is made available for all project partners  Basic web services (e.g., WMS, WFS), and geodatabases are implemented in partner regions  Project partners are able to integrate individual applications in common WMS configure map representations remotely  Common WMS accesses remote data through WMS (cascading), WFS, or OGC geodatabase interface

8 GeoShare Network: Implementation Phase III  All data will be accessible through web services hosted by the partners  Additional “advanced services” (ADS) will be hosted by the partners  All available services can be linked together to complex applications through service chaining

9 Software Solutions  Applications use software from different vendors  Common infrastructure based on OGC compatible (conforming or implementing) software  Focus is on OpenSource software and in-house developments  For first prototype: UMN Web Map Server (Minnesota University) with ArcSDE and PostGIS Intelligent Catalog Server (ICS) based on BUSTER tool (Universität Bremen)

10 The Intelligent Catalog Service  Manages metadata descriptions for all registered data and services in GeoShare Network  Search over terminological, spatial, and temporal domain  System maintains formalized knowledge (ontologies) for these domains  Intuitive queries, logic conclusions, mapping between ontologies

11 Step 1: Selection of Thematic, Spatial and Temporal Domains

12 Step 2: Selection of Keywords, Regions and Time Periods

13 Step 3: Query Results

14 Water Quality Data on WMS 1 (SBU)

15 Background Data on WMS 2 (Catastre Office)

16 Integrated View through Cascading WMS

17 Summary and Discussion  Project still in initial phase  Overall objective: Building a transnational geodata infrastructure  Regional objective (Bremen): Initializing geodata infrastructure for Bremen  Basic infrastructure will be available in September 2003  Advanced services will be available by summer 2004  Focus on the use of OpenSource software  Intelligent Catalog Service  Integration of thematic applications in the partner regions  Thematic focus in Bremen: Implementation of WFD
