Imprecision arises through limitations on semantic and geometric resolution of data representations.
Generalization, and in particular modeloriented generalization, is an important process in this context, because it enables translation between different levels of precision. This paper provides a formal approach to multi-resolution in spatial data handling. It arranges the views such that they correspond to a level of detail. In this context it should be possible to develop a notion of a family of BCAs which vary over a lattice of levels of detail. Doc 2 A topological model for spatial databases - Egenhofer, Frank et al.
