2. Spatial Decision Support (SDS) Knowledge Portal Systematic representation of body of knowledge of SDS
Promotes semantic clarity of concepts commonly used in spatial decision support
Organizes and facilitates access to commonly used resources that aid in solving spatial decision problems
Developed and maintained by the Spatial Decision Support Consortium
http://institute.redlands.edu/sds
3. Definition of Spatial Decision Support (SDS) Spatial decision support is the computational or informational assistance for making better informed decisions about problems with a geographic or spatial component. This support assists with the development, evaluation and selection of proper policies, plans, scenarios, projects, interventions, or solution strategies.
Often multiple stakeholders or decision makers with conflicting interests
Virtually all decision problems involving Earth science data are spatial-related.
Even global change is spatially dependent
4. Community Needs for Spatial Decision Support
Re-usable, modular tools/services that can be put together easily to form a spatial decision support system (SDSS)
most SDS systems and tools developed to date are not reusable
typical approach is to develop from scratch for specific project or application
many components may be common across projects, decision problem types, and application domains
Evaluate existing spatial decision support systems and tools in terms of their appropriateness and interoperability
Understand and formalize the fundamental granules of the spatial decision process and related phenomena
Common vocabulary and framework for semantic clarity
5. Complexities of Spatial Decision Making
Variability (uncertainty) of geophysical inputs
Complex multi-dimensional and heterogeneous data and models describing decision situations
Multiple formats, including: numerical, map, image, text, and other forms;
Large number of available alternatives or a need to generate decision alternatives "on the fly" according to the changing situation
Multiple participants with different and often conflicting interests;
Multiple categories of knowledge involved, including expert knowledge and layman knowledge.
6. Knowledge-Base Approach
Organize the knowledge in SDS to represent/formalize the meanings and relations of SDS components
Enable easy access to the SDS components
Improve the robustness of the framework
Facilitate interoperability with other existing conceptual models through standardization of terms
Spatial decision process, phases and steps, workflows
SDS related concept definitions and inter-relations
Describe SDS resources using concepts in the ontologies
Partition of concepts into a set of ontologies
7. Canonical Decision Process Steps
Decision context
Assessment, planning, legal/institutional aspects
Decision processes
Phases
Methods and techniques
Algorithms
Data, models, and domain knowledge
Software and other technology
People, participation, and collaboration
Resources
