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 theEU Interreg IIIB North Sea Region programme
Duration: 12/02 – 12/05
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
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)
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
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
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
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)
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
Step 1: Selection of Thematic, Spatial and Temporal Domains
Step 2: Selection of Keywords, Regions and Time Periods
Step 3: Query Results
Water Quality Data on WMS 1 (SBU)
Background Data on WMS 2 (Catastre Office)
Integrated View through Cascading WMS
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
