Spatial database access methods

ACM SIGMOD Record, 1991
In the discussion of research issues in spatial databases (SIGMOD Record vol. 19, no. 4, Dec 1990) we stated the need for a robust framework for analytical comparison of a broad range of spatial access methods. The utility of such a comparison, even of very closely related access methods, was shown in [FALO87]. A necessary precondition for a meaningful

Topological Relations in Spatial Databases

2002
Various models for the representation of topological relations have been developed. The aim of this chapter is to propose a comprehensive view of state-of-the-art models for topological relations in spatial databases. A prominent role is assumed by the CBM (calculus-based method), which offers a small set of topological relations with high ...

Vague Relations in Spatial Databases

2010
While qualitative relations (e.g. RCC8 relations) can readily be derived from spatial databases, a more difficult matter is the representation of vague spatial relations such as 'near-to', 'next-to', 'between', etc. After surveying earlier approaches, this paper proposes a method that is tractable, learnable and directly suitable for use in natural ...

On the Estimation of Spatial Database Performances.

2014
We discuss the results of experiments on spatial databases, aiming to empirically derive parameters for estimating disk occupancy and performances since from the conceptual stages of the design process. This opens the way to the definition of an estimation methodology, which should let a designer evaluate the quality of alternative design choices based
