Integration of heterogeneous software components in a pesticide decision support system

The paper presents a project called GIMMI (Geographical Information and Mathematical Model Inter-Operability), which is funded under the 5th European Framework Program. GIMMI will develop a middleware based system which is used for the pesticide impact assessment domain. This paper does neither look into the modelling aspects of the system nor into the GIS-related issues. It focusses entirely on an overview of the system architecture which has been developed during the first project year. The goal of this architecture is to make GIMMI available for different distributed environments, as they may occur in practice.
