Goals



Geodata – Geoinformation

Geographical or geospatial data (geodata) and geoinformation, obtained through combinations of geodata, reproduce or describe a territory and its characteristics by means of spatially referenced data such as coordinates, postal addresses, place namesor similar criteria.



Geodata services (Geoservices)

Geodata services or geoservices are electronic services or network applications which facilitate and simplify the use of geodata and allow access to structured geodata.



Spatial Data Infrastructure SDI

• In order to use geo-information effectively, it must be up-to-date, compatible and available on a broad basis.

• Coordinated policies as well as uniform standards and technologies are essential on global, national and local levels.

• A Spatial Data Infrastructure is a public access system

of (political) measures, institutional facilities, technologies, data and people allowing a common exchange and efficient use of geographical information

• The goal of a SDI is to provide users direct access to geodata, geoinformation and geoservices from a variety of suppliers.



Spatial Data Infrastructure SDI

• SDIs exist on different levels:

- the Global Spatial Data Infrastructure promotesinternational cooperation since mid 1990’s

- the National Spatial Data Infrastructure includespublic organisations as well as private enterprises on the national level

- the Federal Spatial Data Infrastructure concerns the geodata of the Confederation

- cantons set up Cantonal Spatial DataInfrastructures



Federal strategy for geoinformation

Interdepartmental GI&GIS-Coordination Group: • National Spatial Data Infrastructure for the whole

country• Basic geoinformation shall be available easily

and on easy terms• Coordination with the cantons and communities• New legal bases if needed• Personal data protection, copyrights, liability, etc.

are taken into consideration• Standards for data production and data transfer

(metadata, modelling, formats)



The federal strategy for geoinformation

passed by the federal council in June 2001



The National Spatial Data Infrastructure

• The Federal strategy demands the implemen-tation of a user-friendly, decentralised but networked national spatial data infrastructure (NSDI), including political, legal, organisational, financial and technical components.

• The implementation concept focuses on - political and economical profit (added value for public sector, organisations, citizens)- a positive impact on the use of geoinformation- a well functioning SDI on the national level

Includes a system of procedures, institutional facilities, technologies, data and manpower which can make the efficient application of geodata possible.



Partners and sponsors of the network e-geo.ch are:

• Federal government, federal offices• the cantons,• cities and municipalities, • the Swiss Organisation for Geographic Information

(SOGI), representing the private industry, educational institutions and non-governmental associations and organisations.

The implementation of the NSDI was one of the triggers for the

• Federal Act on Geoinformation (GeoIG) (effective 1.07.2008)- Geodata/geoinformation: data access and data use- National Survey- Cadastral Surveying- Swiss Geological Survey

• … together with various ordinances

Art. 40 Advancement of education1 The Confederation and the cantons shall encourage

education in the field of geoinformation.2 They shall ensure that the education curriculum

and final qualifications at all levels correspond tothe latest state of science and technology.

Art. 42 Advancement of researchThe Confederation and the cantons shall encourage research in the field of geoinformation.

Basic or official geodata are spatial data which are produced and needed in public interest and with public funds and which are under responsi-bility of public body. (see catalogue in the ordinance GeoIV)

Network e-geo.ch

Basic geoservices are of great interest to the clients of the NSDI. On the federal level, swisstopo has developed a geodata portal using a web technology which enables applications to communicate with each other over standardized interfaces. Different geographical services can interact and geoinformation can now be networked. The portal is used by various federal offices. Similar services have been established by cantons for their data. Eventually they shall all work together.



swisstopo runs the infrastructure for more than 20 thematic federal geoservices



e.g.: Location of radio transmitters (OFCOM)



GISGeol (Database of geological reports)



Geological Data Viewer (swisstopo)

• quality, accuracy, reliability• integrity, coverage• consistency, compatibility, combinations• easy access, simple use• visualisation• actuality, updating• time series, archives• costs, tariffs, prices• education, training, research• publications, user groups



Let’s make it a success!

To reach the goal "establishing a National Spatial Data Infrastructure", it is essential to include all partners and to establish a network of all parties interested in geoinformation.

The more suppliers and users participate in the NSDI, the more effective, successful and useful it will become.
