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 names
or 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 promotes
international cooperation since mid 1990’s
- the National Spatial Data Infrastructure includes
public 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 Data
Infrastructures

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 implementation 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

National Spatial Data Infrastructure (NSDI)
Includes a system of procedures, institutional facilities,
technologies, data and manpower which can make the
efficient application of geodata possible.

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

and final qualifications at all levels correspond to
the latest state of science and technology.
Art. 42 Advancement of research
The 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 responsibility of public body.

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.

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.
