GIS-application development with GEOOOA
We stress the need of a domain-tailored requirements engineering method for the development of GIS-applications. To this end, we discuss three GIS-application scenarios we have frequently encountered in real life projects. Our investigation reveals that conventional RE-methods like Coad/Yourdon`s Object-Oriented Analysis (OOA) are not capable of modelling GIS-specific requirements appropriately. To overcome the deficiencies of conventional OOA we introduce GEOOOA which extends OOA by domain-tailored primitives and allows for a more adequate treatment of GIS-specific requirements. We provide GEOOOA-models of three application scenarios which serve as first validation steps for the usefulness of the approach. Finally, we propose some methodological advices for a proper application of GEOOOA and sketch the GEOOOA-tool environment.
