English abstract:
Space and time are the most prominent features of our everyday experience. While we can move
relatively freely within and interact with space, time imposes stricter restrictions on us. We are
mere bystanders to the ever-changing flow of time. Close observation of our environment reveals
that nothing stands still and everything changes constantly.
It is generally acknowledged that GIS need to account for the dynamic aspects of the world.
The almost exclusive depiction of static phenomena (spatial configurations) in GIS reveals its
close historical ties to Cartography. A first call to move beyond the "map metaphor" and focus
on "spatial processes, changing the spatial configuration" can be found in Abler et al. (1971). An
integration of processes in GIS will help to answer questions related to "When something
happened or will happen" (Frank 1998). For a thorough review focusing on the dynamic aspects
in GIS research see Worboys (2005). The vision of a fully dynamic GIS requires a simple,
combinable, and scalable formal application-independent approach (Weiser and Frank 2010).
In this work we present our ongoing research on (1) how to represent processes over multiple
levels of detail, (2) their combination, and as a result (3) reasoning over processes. We build
upon the notion of "processes over multiple levels of detail (LoD)" we have formalized
previously, using partial function application (Weiser and Frank 2012). We now focus on the
challenges that arise from combining those processes.
