The problem of managing multiple representations of the same spatial data at different levels of granularity is widely recognized as a relevant one in the spatial database community. We focus our attention on the phase of conceptual design. We provide (conceptual) spatial data models with two distinct, but related, granularity dimensions, namely, a purely spatial one and a semantic one, and we show that they allow us to capture scale as well semantic changes and to constrain the relationships between them. We give an account of the resulting (conceptual) representation formalism, called Granular GeoGraph, and we exhibit its potentialities by applying it to a real-world case study, taking advantage of a JAVA tool we developed for graphically synthesizing Granular |
