Analysis methodology and modeling of a shared Spatial Reference Information System: SIREME

Abstract

SIREME project, lead by the research center Cemagref, aims to put in place geographic information systems able to support environmental and quality processes at the production scale. This paper describes the methodology used for GIS analysis and modeling and its testing on a pilot project. This methodology is based on systemic analysis and on the implementation of an analytical process of information systems. Classical method and modeling tools (MERISE) have been used, improved by object-oriented approach like: · An approach reinforcing preliminary studies and employing prototypes. · Use of object-oriented tools as UML: inheritance relations, use cases, specialized design case tool for spatial database. · Metadata definition able to support generic models and future evolutions of the system. An important point of the approach is to integrate modeling data standards in the purpose to develop EDI (Electronic Data Interchange) between information systems used in agriculture. An example will support the presentation: The conceptual modeling of a shared geographic information system related to field crop productions under environmental and quality management system (AgriconfianceÒ) binding co-operatives and farmers.
