A Method for the Integration of Existing GIS and Modelling Systems

The integration of existing modelling and geographic information systems (including GIS) is an important activity that enhances the value of these systems. In this paper, we present a simple and comprehensive approach for the integration of separately developed software systems. Any information system can be integrated using our methodology without the complexities introduced by providing an interpretation of a universal language. The design of our integration methodology consists of four separate components , the protocol for communication, a message queuing system, wrapping software and an integration manager. Relevant conceptual models and implementation techniques are discussed in the paper. We also describe some examples of the software we have successfully integrated and present an example script for managing a simple integration activity.
