A domain specific language for spatial simulation scenarios

Spatial Simulation in the context of Geographic Information Systems (GIS) is used primarily to assess the evolution of spatial variables over time. Since the 1990s two main techniques have been applied to perform this sort of spatial analysis: Cellular Automata [1] and Agent-based modelling [2]. The simulation models produced with these methods tend to be quite specific, only usable within the particular field of application, largely due to the multi-dimensional and heterogeneous character of spatial data. Mainly for this reason, modern multi-purpose GIS packages, such as GRASS or ArcGIS, largely lack tools dedicated to this technology.
