Integrating dynamic environmental models in GIS: The development of a Dynamic Modelling language

An integrated, executable mathematical modelling language for environmental and ecological applications has been developed to create and run Dynamic Models in a GIS. The modelling language is embedded in the GIS, providing the ability to model complex space-time systems free from the technical burdens of database management and algorithm optimization. The spatial modelling language uses a structured script, which is illustrated here by an example of a model of plant dispersion.
