Managing multiple representations of georeferenced elements

Abstract

The paper presents a framework for the management of multiple representations of georeferenced elements in a GIS environment. This solution is presented from a database perspective, and is based on extending the DBV version approach with view facilities. Given this environment, users can build consistent views of their modelled world, creating and combining different representation frameworks. The environment dissociates the logical dimension from the physical dimension, liberating users from concerns about implementation details.
