Demand for geodata
General demand

• all spatial planning and decision making needs
• a description of geotopography of the earths
  surface
• a connection to the earths surface
• the description of geotopography consists of
• pictorial and objectoriented planimetric
  information
• height information
• as geobasis

• the connection is given
• as georefence

Global Responsibility

• We may not be affected directly by climate change
  with life destroying droughts, floods, storms and
  other disaster
• ... but we - and life of future generations -
  will not escape uneffected !!!
• We have a global responsibility.
• Developing our understanding of these issues is
  extremely important.
• All sectors need to play an equitable part.
• GIS-technologies will have a key role to play in
  both monitoring impacts on our enviroment and in
  identifying solutions
• by Mr. Dan Wallace, Minister of State, Ireland,
  2000

• accuracy by aeroplane
• up to one meter resolution and some
• meter accuracy by satellite
• (e.g. IKONOS)

• Photogrammetric measurement

Opening of geodata treasury

• is the political will, see Use of geoinformation
  in the Federal Repuplic of Germany, February14th
  (enclosed paper)
• is part of federal cabinets program from 20.
  October 1998 (part Information and Communication
  policy)
• means
• making all geodata available
• making geodata available for everyone
• by fast access
• by reasonable prices
• by same conditions

- Opening geodata treasury -

Opening of geodata treasury

• Requires
• a series of step by step actions
• of and between government
• Consequences
• creation of a Commitee for Geodata with heads
  from government and business
• initiation and encouragement of qualified SDI
  projects from government and business

Geobasis NRW

• Topic
• realization of freedom of information for
  public geobasis data of NRW
• public cadastre and topographic data
• with first priority for business
• and then for business and enduser
• that enables to integrate thematic geodata
• because of systemindependence and
  interoperability
• to get an extensive governmental informationsystem

Geobasis NRW

• Problems
• old concepts for cadastre (ALB/ALK) and
  topographic (ATKIS) information systems
• no systematic object-related view in ALB/ALK
• strong differences between ALB/ALK and ATKIS
• no consistant data modelling between cadastre and
  topography
• difficulties in realisation of cartographic
  aspects
• no standard notation of the data models
• no concept to integrate metadata (data quality)

ALKIS-Concept

• integration of the graphical data and the
• attribute data
• A L K I S / A T K I Snew
• integrated Data Modelling
• Standardized notation
• Integration of metadata
• ALKIS enable to manage historical data
• Enable to manage cartographical data
• possibility of integration of cadastral and
• mapping data (vertical integration of data)

Geodata infrastructure NRW(GDI NRW)

• Topic
• linking all puplic and private geodata of NRW
• conception
• as well as the physical link
• based on OGC strategies
• for government, business and enduser

• Problems
• up to now there exists no real market for
  geodata
• because geodata are available extensivly and
  in
• different formats
• without enough geodata server and meta-
  information-system solutions
• and without a connection between them

• Barriers
• no standards
• project oriented data capturing
• restrictive and intransparent rules for access
• missing meta information
• redundant capturing and value adding

- Situation geodata market -

Geodata Market

• Activities
• situation is not really known
• to realize geodata market investigations have to
  be done to capture and analyze the situation
• next step is to look for suited activities to
  overcome the barriers
• a study is done as one part of GDI NRW
• it can be used as basis for product design, value
  adding and delivery

Interoperability

• Topic
• for realization of a SDI and geodata market with
  reasonable and economic use of geodata an
  interoperable geoprocessing is required
• Open GIS Consortium serves the inter ...
• ...rests of all sectors of the industry to
  realize a component - based infrastructure for
  geodata and develop such a SDI and geodata
  market.

- Interoperability -

36
Interoperability

• Interoperable Geoprocessing
• geodata integration
• maximized benefit from legacy geodata
• geographic feature semantics translation
• network-based geoprocessing
• better use of databases
• componentware
• geoprocessing integrated into workflow
• new non-expert users and market growth

Interoperability

• Open GIS is
• transparent access to heterogeneous geodata and
  geoprocessing resources in a network environment
• Open GIS needs
• a comprehensive open interface specification
  which enables developers to write software that
  provides these capabilities
• Open GIS enables
• to build task-specific geoprocessing functions
  into any information system
• to bring new capabilities to a wide variety of
  user environment.

Transparency on Geodata Market

• Topic
• transparency is required to stimulate geodata
  market
• is given by a meta information system and a
  meta meta information system that inform about
  data availability and address and conditions for
  access
• is given by certificates for homogeneous data
  description and conformity with data quality

- Transparency geodata market -

Transparency on Geodata Market

• Meta information system for geodata
• is in preparation by DDGI
• based on a consistent and harmonized description
  model
• will be implemented in 2001 at Geoforschungszentru
  m Potsdam
• enables geodata owner to present products

Transparency on Geodata Market

• Certification of geodata
• is realized by DDGI

• consist of a conformity check
• of data description with DDGI quality model
• of data with data description

  cooperate between
• all geodata relevant disciplines
• public and private sector

• producer, owner, vendor and customer
• all nations worldwide
• all public levels

- Co-operation geobase -

  linking
• (OpenGis)
• easy and fast data access and access for
• reasonable prices
• and...

- Improved Conditions -

Improved Conditions for Spatial Activities

• ... no more barriers hinder geodata use,
• because
• data are harmonized
• data are up-to-date
• data are compatible

- Improved Conditions -

44
Increased Economy of Spatial Activities

• because of the improved conditions
• an increased real use of geodata
• therefore a more economic and
• high-class work overall
• therefore new and high-class
• working fields and jobs
• and a better planning and protection
• of our living space
• and therefore a better...

- Increased economy -

... Quality of Life ...
... as already mentioned ...
so lets stimulate the community to invent new
