Towards Spatial Data Infrastructures in Germany and Europe

1
3rd Cambridge Conference 21 - 25 July 2003
The decentralised approach to mapping of the
Federal Republic of Germany a model for
establishing the European Spatial Data
Infrastructure (ESDI)?

Kartographie und Geodäsie www.bkg.bund.de

• Official Surveying and Mapping is the task of the
  16 federal states each being responsible for its
  state territory in terms of
• Geodetic reference frames
• Real estate cadastre,
• Topographic mapping.

3

• Collaboration of the states organised by AdV
  (since 1949)
• Common specifications for
• Geodetic framework
• Real estate cadastre
• Topographic mapping
• IT-based projects (AFIS,
• ALKIS, ATKIS)
• Pricing policy
• Sharing experiences and technologies

Decisions of the Federal Government with respect
to improving coordination of the provision and
use of geoinformation in Germany

• 1996 Establishment of the national geodata
  centre (GDZ) assigned to IfAG

• 1997 Establishment of the Bundesamt für
  Kartographie und Geodäsie (BKG) (Federal Agency
  for Cartography and Geodesy) as successor of the
  research institute IfAG

• 1998 Establishment of the Interministerieller
  Ausschuss für Geoinformationswesen IMAGI
  (Interministerial Committee for Geoinformation)

5
National Geodata Centre (GDZ)

• Partner of the state mapping agencies
• Technical coordinator for country-wide
• topographic datasets
• Service centre
• Quality assurance of the ATKIS data sets
  delivered by the state mapping agencies
• Providing the AdV metadata information system
  (AdV-MIS)
• Online delivery

6

• BKGs mission
• to provide a geodetic and cartographic
• infrastructure taking account of the
• responsibilities of the states and the
• overall responsibility of the federation
• (e.g. the national geodata centre)
• to carry out applied research and
• technological development
• to represent geodesy and
• geoinformation on the international
• level

7
Mapping Germany in a decentralised approach
Common reference data sets for Germany

• Geodetic reference frames
• including a network of 260 GPS
• permanent stations

• Official multipurpose cadastre
• Automated Real Estate Map ALK
• Automated Real Estate Register ALB
• (in the future ALKIS, the new ISO- based
  Real Estate Cadastre IS)

• The Authoritative Topographic-
• Cartographic Information System
• ATKIS

• The national gazetteer

Interministerial Committee for Geoinformation

• established in 1998 by the Federal Government
• Objective Coordinating the German SDI ?
  GDI-DE?

Tasks of IMAGI - Conceptual framework for GDI-DE

• Development of GeoPortal.Bund?, starting with
  GeoMIS.Bund?

• Coordinating pilot projects of the Federal
  Government
• and States to investigate the resources needed to
  build
• the homogenised NGDB and to develop the GeoPortal

10
German Spatial Data Infrastructure (GDI-DE)
GDI-DE NGDB, network, services,
standards
National Geo Data Basis NGDB reference data,
thematic data, metadata
GeoPortal.Bund the central point of entry to
GDI-DE
11
Evaluation of the German approach to national
mapping

• According to criteria suggested by the GINIE
  project
• Sustainable political support at the highest
  level

• Co-ordination

• Phased implementation

• Selling the benefits

12
Resolution of the German parliament 15th
February 2001

• Federal Government is asked
• to push ahead the implementation of the Spatial
  Data Infrastructure for Germany as a public
  infrastructure
• to promote the interdepartmental use of GI in
  public services
• to coordinate the GI activities of the Federal
  Government, and to support the Länder (states)
• to promote collaboration with the private sector
  and academia

13
Resolution of the German parliament 10th April
2003

• Acknowledgement of IMAGIs achievements
• Federal Government is requested to increase the
  efforts devoted to the establishment of the
  GDI-DE
• Underlining the necessity of coordination of the
  GDI-DE process by the Federal Government

14
Lessons learned for the set-up of the ESDI

• Strong political support is needed on the
  European level (EP, Council, EC) as well as in
  the Member States

• Need for a common process of specifying the
  various components that belong to the ESDI
  ?Eurogeographics Eurospecs

• Need for a unit on the European level charged
  to coordinate the development and implementation
  of
• ESDI

• Need for culture of sharing strategies, (pricing
  and licensing) policies, experiences, and
  practical solutions
