Arnold Bregt From GIS-application to geo- knowledge infrastructure
Two Developments Two from data to knowledge From vertical to horizontal information systems
Data Information Knowledge Wisdom

Geo-data Collected with geographical phenomena in mind e.g. water, soil, topography One responsible organization From 1960 conversion from analog to digital In NL government geo-datasets
Framework VerticalHorizontal DataGeo-data InformationGeographical information system (GIS) Knowledge
Geographical Information systems (GIS) GIS applications for a specific problem or question Started around 1980 Special software (e.g. Esri) Applied within one org. Development and maintenance of applications expensive Problem: changing questions
Framework VerticalHorizontal DataGeo-data InformationGeographical information system (GIS) KnowledgeSpatial Decision Support system (SDSS)
Spatial decision support systems Started around 1990 Data, processing and knowledge Data integration and for specific domains Problems: not really used by decision makers Decision making is complex
condition suitability scenario quality

Spatial data infrastructure Started around 1991(Canada) Clinton order in 1994 The same data for many applications (horizontal) GI becomes a policy and organization issue Standards are crucial (ISO, OGC, W3C) Problem very data driven
Definitions of SDI Utility view: SDI is a network facility for accessing and sharing spatial data. Component view: spatial data, standards, policies and service technology and institutional framework Utility and goal: a network facility for advancing knowledge in a given context through accessing and sharing spatial data

Geo-knowledge infrastructure Still on the drawing board! Technical component: Knowledge components for certain functions (knowledge agents) Human component: training experience, collaboration experiments
