Spatial Data Infrastructure Frameworks to Support Decision Making for Sustainable DevelopmentMary-Ellen Feeney Abbas Rajabifard Ian Williamson Department of Geomatics, University of Melbourne, Australia
Overview • Decision making for Sustainable Development • SDI Concept and Decision making • Brief Introduction to the concept of DSS • The DSS & SDI context • Impacts for Developing SDIs to support DSS • Exploratory Case Studies of different SDI • Models for DSS support - regional Australia

The SDI concept & Decision Making The principle objective for developing SDI is to achieve better outcomes from spatially related economic, social and environmental decision-making.

How do SDIs support Decision Making? • Through facilitating the provision of standardised, interoperable datasets and information that are accessible, useable, exchangeable • But, are data and information enough to support decision making?
1 Decision Space Solution Space 2 Spatial Data Information 3 Processing Decision Support The Nature of Decision Making?
Generally computer-based information systems Support decision-making activities in the exercise of judgement Do not actually make the decision Characterised by integrated modeling and analysis facilities, including … Decision Support Systems (DSS)
Decision Support Systems (DSS) • tools for obtaining, analysing & presenting information • modeling & simulation tools • multi-criteria modeling for selecting from a set of defined alternatives • Expert systems for rule-based decision making in defined situations • Life-cycle analysis & green design tools.
Aid rather than replace decision makers Decision Support Systems • Generally combinations of ‘SYSTEM’ tools • Can restrict or expand decision options • May facilitate user-directed change • Can be for specific decision environments/ generic tool
Decision Support Systems vs Tools • = complexity ie. • number of criteria; • incorporate preferences & values; • number of decision-makers • decision-making model; • support existing data & ‘gaps in data’; • generation of alternative (prioritised) solutions
Why What How When DSS & SDI : CONTEXT Relevance and Significance ?
Why What • Questions are we trying to answer • - sustainable development objectives • Data do we require to answer them DSS & SDI : CONTEXT • Capability to validate data quality, • Process data quantity quickly & effectively & • Model new and more variable decision making
To ask the necessary Questions How When • To model data to achieve satisfactory answers • To better manage spatial information towards Sustainable Development Objectives • Need to incorporate time-frames into decision making processes • e.g.. multiple stages, time-frames for criteria • Need for temporal data modeling developments (time series data analyses) DSS & SDI : CONTEXT
Developing SDIs to support DSS ... • understanding of other’s data needs/resources • awareness of data availability, quality & limitations • Improved data by publishing & standards coordination. • Increased confidence in data use - consistency • Precipitant for collaborative data-sharing agreements. • data availability, collection, storage, access, • users with differing expertise in the GI use • incentives to integrate social, environmental, economic & spatial data • transfer of R&D to stakeholders
Classification of Different SDI Models • 1. motivation for development • 2. expected outcomes • 3. management • 4. participants • 5. measures of progress • 6. political/administrative function • 7. time frame-committment
Herbert River Information Centre- QLD Developing SDI using a Product Model: 1. Sharing/modification existing datasets, collection of key additional datasets 2. integrated databases of region 3. unincorporated partnerships between 11 agencies 4. private & public sector (3 tiers) 5. Completion of the Mapping Project on time 6. Regional (Sub-State) 7. fixed project period - 3 years
Herbert River Information Centre- QLD Developing SDI using a Process Model: 1. Resource that supports spatial decision-making & planning for natural resource management 2. Resource Information Centre- GIS facilities, consultation, project management, data access & coordination 3. HRIC Management - Independednt of partners, 4. 6 partners - private & public sector (3 tiers) 5. Financial & Objective Sustainability - 3 years-10 6. Regional (Sub-State) 7. 10 year + (period after which partnerships reviewed)
Integrated Information Management System - NSW & QLD Developing SDI using a Process Model: 1. Facilitate discovery & use of resources for Catchment Management Decision-making 2. Information Management Systems incorporating access to data & Modeling Systems 3. University & Government Partners, Govt. Funding 4. 3 partners - 2 State public sector, University QLD 5. Establishment, Prototype testing & Feedback 6. Regional (Sub-State) particularly Catchment-oriented 7. Dependent on Community & Agency Uptake
vs Conclusions in decision support for sustainable development... • Process Models for SDI development: • offer access networks to data • forums of consultation (web-based or service centres) • DSS to support the application & modification of data • Product Models for SDI development: • improved data availability, coordinated collection, cross-agency data collaboration • integrated data products with defined quality & maintenance time-frames
Acknowledgements These findings are from exploratory case studies in ongoing PhD research. They provide a broad-brush review of initiatives central to State SDI developments in Australia. They result from pilot-work in selecting & testing criteria for the comparison of SDI & DSS developments that is undergoing continuing development & refinement. • Land Victoria of the Victorian Government • Land & Property Information Centre of NSW • Department of Technology & Management NSW • Australian Research Council • Spatial Data Infrastructure Research Group, Department of Geomatics, University of Melbourne
