Spatial data infrastructure

As spatial data infrastructure (SDI ) is a complex network for the exchange of spatial data is referred to in the research data infrastructure in which spatial data producers, are service providers in the Geo - range and spatial data users on a physical data network, usually the Internet, linked together. The overall architecture follows the SOA thoughts.

Specifically, it consists of basic geodata and geodata based on spatial data servers ( database) are stored, standardized services ( Geoservices ), which allow access to and editing of spatial data and provide geo-portals (or other clients ), the corresponding user interfaces available. The ISO 191xx series and published by the Open Geospatial Consortium implementation specifications play a key role in this context.

A spatial data infrastructure to enable the multidisciplinary access to all available spatial data, the present separately otherwise in the individual institutions. You can apply to different spatial regions to be limited (eg city, nature reserve, ...) or hierarchical levels (community, state, country, continent, world).

A spatial data infrastructure consists of both a technical infrastructure for data provision, on the other hand also mandatory for legal, organizational and technical regulations.

At the European level, that is, the European Union, the European Geodateninfrastrukur ESDI is ( European Spatial Data Infrastructure) built, which is significantly influenced on the initiative and with the same EU directive INSPIRE ( Infrastructure for Spatial Information in the European Community ).

With the Spatial Data Infrastructure Germany (GDI -DE), as it is built up of federal, state and local governments since 2003, not only created the conditions for the implementation of INSPIRE in Germany, but also joint projects in the interest of the public administration and the geoinformation industry forward. The common rules for the construction and operation of the GDI -DE are regulated in an administrative arrangement between the federal government and the states.

The hierarchical structure of the public administration in Germany includes the following projects:

  • GDI - DE, at the level of the Federal Republic of Germany
  • GDI - state, at the level of the federal state
  • GDI - local, at the level of each local authority area

The hierarchical structure of the public administration in Switzerland includes the following projects:

  • NSDI ( National Spatial Data Infrastructure ), at the level of federal administration of Switzerland, Swiss cantons, municipalities and third parties
  • FSDI ( Federal Spatial Data Infrastructure ), at the level of Switzerland the federal

The spatial data infrastructures of the public administration are complemented by the numerous contributions of the local and global economy as well as applied research.
