Title: Geometric Modeling of Spatial Entities at Multiple Levels of Resolution

Abstract. The representation of spatial data at different resolution is a topic of relevant interest in spatial information theory. In particular, we consider applications within geographic systems, where representations of topographic maps at different levels of accuracy/detail is a major issue. We will describe a few models proposed in the literature as well as a new model in which metric aspects concerning changes in accuracy can be controlled separately from topological aspects related to changes in detail.
