In this paper we outline an interaction model for spatial databases, based on the exploitation of the topological invariant, a topological annotation of the spatial database. In particular, we consider zooming primitives suitable for browsing in massive sets of spatial data visualized in a fish-eye view fashion, and present their implementation in terms of manipulations of the topological invariant.

Abstract
In this paper we outline an interaction model for spatial databases, based on the exploitation of the topological invariant, a topological annotation of the spatial database. In particular, we consider zooming primitives suitable for browsing in massive sets of spatial data visualized in a fish-eye view fashion, and present their implementation in terms of manipulations of the topological invariant.File in questo prodotto:
