AbstractConsidering the costs and the effort associated with the construction of geographic databases, it is important to search for instruments that increase GIS usefulness through data sharing among different user groups, each one of them with a particular set of applications. However, distinct applications often have diverse perceptions of reality, and therefore work with different sets of concepts about the same geographic entity. These differences often require more than one representation for each geographic entity. Thus, if several applications share the same geographic database, the GIS must take over the responsibility to allow multiple representations for each geographic entity, each one of them adequate for a group of applications. This need is particularly important in the case of urban GIS applications, in which there is a wide variety of information classes and potential users, each with its particular needs regarding the representation of the objects. This article presents an analysis of the multiple representations problem in GIS, indicating the need for this feature in urban applications through examples. Alternatives are discussed, and potential problems for the implementation of this feature in GIS are indicated.
