Supporting Requirements Engineering for SMALLWORLD-Applications

method with geo-primitives which are specially suited for GIS-specific requirements. Since the applicability and success of any software engineering method depends heavily on appropriate tool support, we propose the GEOOOA-tool, a CASE-tool supporting the development of GEOOOA-models. In this paper, we briefly report on the editors, browsers, validators, and documentation aids of the GEOOOA-tool and show how GEOOOA-models can be processed by the SMALLWORLD GIS. Major parts of the tool and the SMALLWORLD interface have already been implemented. A first commercial version will be available in January, 1998
