The SDI concept & Decision MakingThe 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 How do SDIs support Decision Making?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?

Decision Support Systems (DSS)

• 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)

• tools for obtaining, analysing & presenting information

• modeling & simulation tools

• multi-criteria modeling for selecting from a set ofdefined alternatives

• Expert systems for rule-based decision making in defined situations

• Life-cycle analysis & green design tools.

Decision Support Systems

• Aid rather than replace decision makers

• Can restrict or expand decision options

• May facilitate user-directed change

• Can be for specific decision environments/ generic tool

• Generally combinations of ‘SYSTEM’ tools

Decision Support Systems vs Tools = complexity ie. = 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

DSS & SDI : CONTEXT

• Why• What• How • When

Relevance and Significance ?

DSS & SDI : CONTEXT

• Capability to validate data quality,

• Process data quantity quickly & effectively &

• Model new and more variable decision making

Why

What•Questions are we trying to answer

- sustainable development objectives

• Data do we require to answer them

DSS & SDI : CONTEXTHow• To ask the necessary Questions

• To model data to achieve satisfactory answers

• To better manage spatial information towards Sustainable Development Objectives

When

• 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)

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

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

Developing SDI using a Product Model:

Herbert River Information Centre- QLD

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)

Developing SDI using a Process Model:

Integrated Information Management System - NSW & QLDDeveloping 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

Conclusions

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

in decision support for sustainable development...

AcknowledgementsThese 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.
