GRID-Europe is extending and developing its filed of activities using Spatial Data Infrastructure (SDI), the state-of-the-art information technology, to make the extensive archive of geo-spatial and tabular databases compiled over the years available to public.
An SDI could be defined as the base collection of technologies, data, human resources, policies, institutional arrangements, and partnerships that enable the availability, exchange of and access to geographically-related information using common practices, protocols, and specifications. SDI consists of a framework that enables users with different mandates and disciplines to operate in a cooperative and cohesive manner to acquire access, retrieve, analyze and disseminate geospatial data and information in an easy and secure way. It particularly helps to improve the efficiency of development, management, use and maintenance of geospatial databases.
The concept of SDIs reside in “working smarter, not harder” by reusing data, technical capabilities, skills, intellectual effort and capital, through the sharing the costs of people, technology and infrastructure. SDIs rely on the development of policies, technologies, data, common standards, standard practices, protocols and specifications such as those of the Open GIS Consortium (OGC).
Based on a long experience in managing data and metadata from many international programs through the Internet, GRID-Europe has a good knowledge and skills the following areas:
- Standards: OGC (WMS, WFS, WCS, WPS, CS-W), ISO (19115, 19139), Dublin Core
- Metadata: Geonetwork
- Databases: PostgresSQL, MySQL, Access
- Spatial Engine: PostGIS, ArcSDE
- Web Mapping: UMN Mapserver, ArcIMS
- GIS Server: ArcGIS Server, GeoServer
GRID-Europe SDI aims to support and serve data through the main international/transnational initiatives:
- UNSDI (http://www.ungiwg.org/unsdi.htm)
- GEOSS (http://www.earthobservations.org)
- INSPIRE (http://inspire.jrc.ec.europa.eu/)
The PREVIEW Global Risk Data Platform is the first Geo Portal supported by the GRID-Europe SDI.
The added value of the GRID-Europe SDI is that it will benefit of distributed computational technology, allowing the user, not only to find and discover data in a standardized and interoperable way but also to analyze and process large amount of high resolution data.
This technology will be explored in the context of the enviroGRIDS EU research project, managed by GRID-Europe.
