Extending the individual formalism for a more complete modeling of urban spatially referenced data
AbstractThe modeling formalisms currently used to design Spatial Information Systems (SIS) databases provide designers with limited possibilities in the modeling and processing of data. Besides being inefficient in describing spatial reference, these formalisms neglect temporal reference (existence and evolution of objects), give rise to complex models, and isolate processes from the data. In the case of large urban organisations, these limitations create technical difficulties when SIS are being designed. Designing can be facilitated by improving the expressive richness of these models. The goal of this paper is to present an extension to the Individual Formalism (used in the MERISE method) which permits a better description of spatially referenced databases. After having summarized the current problems with existing formalisms, we will present the different solutions elaborated and integrated into a new formalism called MODUL-R. Certain elements of MODUL-R which are particularly useful in urban environment applications are emphasized. These elements will be illustrated with examples taken from an urban SIS prototype, to be followed by a consideration of the potential of MODUL-R.
