2.4. Conclusion
In these examples, we have resolutely assumed a “semantic” positioning rather
than a “computer science” oriented one. We have tried to enlighten the
developments presented with respect to different categories introduced in the
Chapter 1. They are not always explicitly expressed, but clues are scattered all along
the text. Priority was given to addressing in a comprehensive and detailed manner
the different stages of the processing chain, and the choices which are associated.
Indeed, the objective of this chapter was to enlighten and illustrate the stages of
an analysis process in an interdisciplinary context, where a number of points of view
coexist (geomatician, computer scientist, geographer, statistician, modeler, etc.).
Different conceptual frame, methods and tools are chosen according to disciplinary
practices and cultures. This does not exclude the fact that there is a commitment to
respond to the same question. It is the interpretation of the question, through the
specific methodological competences, that makes a difference: the disciplines are
rare where only the formal aspects filter the question and decompose it in a single
frame of reference, without interference from technical systems.
Chapters 3 and 4 deepen two of the four challenges presented in this chapter: that
of the analysis of the evolutions of statistical and spatial relationships and that of the
exploration of processes underlying change. The emphasis will be placed on how
time and space are taken into consideration to account for social and environmental
systems' dynamics. Chapter 3 concerns changes in spatial configurations and
evolution of the spatial entities making up these systems. In chapter 4, the focus will
be on the spatial interactions and their role in driving these systems' dynamics.
