Approximations for a multi-step processing of spatial joins,alse hits from the set of candidates. For this purpose, we investigate various types of conservative and progressive approximations. The performance of the approximation approach is evaluated with data sets from real cartographic applications. The results show that this approach considerably reduces the total execution time of the spatial join.

First experiences with GEOSTORE, an information system for geologically defined geometries,visualization of horizontal and vertical intersections with 3D-faces. GEOSTORE has first been realized on top of a relational DBMS and secondly on top of an ODBMS. For the 3D-visualization of the geological layers and faults a coupling with GEOCON, a 3D-construction and modelling tool for geological surfaces, is realized via remote procedure call.

A storage manager for the development of spatial data structures,ple spatial data managers can be significantly increased. Our results lead to a new I/O cost model for storage managers, and this can be used to provide new design criteria for spatial data structures.

Multiple representation modelling and querying, finally given. Although motivated by spatial applications, this extension is useful for a variety of other applications such as cooperative query answering . In particular it allows querying without exact data knowledge.
