A central aspect of the research pursued at the research group for Geoinformation is the use of formal methods in GIS. The formalism and the automatic checking of syntax combined with the possibility to observe the functioning of the described mechanism helps to assure that one has a correct description of the situation of interest. Much effort is spent on honing our tools to describe objects and operations (Frank, Kuhn et al. 1997).
Formal methods are applied to a variety of topics. They are used for the formalization of laws related to land administration (Navratil 1998), for the formalization of children’s mental models (Twaroch and Frank 2004), and for the development of agent-based models for passenger transportation (Pontikakis 2004, Pontikakis 2005). Other topics of interest are navigation: wayfinding (Grum 2005), decision making and spatial reasoning (Achatschitz 2005), as well as spatial optimization modeling and spatio-temporal analysis (Shirabe 2004, Shirabe 2005).
