personal GIS = spatial PIM (Personal Information Manager)
Andrew U. Frank, Geoinformation TU Wien
The modeling of process is a long-standing research question in GIScience:
- space - time - process ontology
- modeling process semantics
- integration of plans and observations (i.e. future and past) in a
Many of us use a Personal Information Manager (PIM) software, often
found in a mobile phone, to register contacts, maintain the daily
schedule etc. These systems are often time, but seldom space aware. A
spatial PIM should be a special kind of personal GIS.
Spatial PIM is a good case study for GIScience, because it is simple and
we understand the desired behavior well; we can use it ourselves and
correct misconceptions quickly; our own use leads to simplifications but
not simpler than possible.
Two research questions are currently addressed:
- logical connection between the process models of the three tiers. How
to link a Partial Differential Equation to a algebraic model of physical
objects? how to connect operations on physical objects to the meaningful
interactions with social constructed objects?
- modularization of process models to allow combinations and to achieve
a hierarchical structure to avoid the combinatorial explosion when planning.
The combination of different categorical models of processes and
planning with a 'shortest-path algorithm' is given by an elegant and
implementable formula. This may serve as a model how to achieve the
