CONSTRUCTS–ASPECTS
* Characterizing geospatial decision problems in terms of two basic
dimensions, ranging from simple to complex, then from content
to context. Solving complex decision problems motivates the use
of GIS. More complex decision problems are likely to require
more complex workflows.
* A general assessment level provides insight an at overview level,
focusing on convening, process, and outcomes of the decision
situation.
* In slightly more detail is an assessment by phase to describe the
overview categories, but for each of the phases involved.
* The third level, a construct assessment by phase, details
constructs for each of the phases. The fourth level, a
construct–aspect assessment by phase, details aspects of all
constructs by phase in a decision problem.
