Random Fibre and Surface Systems,rged within .(.) steps giving .(.). This result implies that for a large class of metrics . in the plane the .-Voronoi diagram of . points can be computed within optimal .(. log .) time. Among these metrics are, for example, the symmetric convex distance functions as well as the metric defined by the city layout of Moscow or Karlsruhe.

Random Tessellations and Cox Processes,iderable savings in storage space, without losing efficiency in any other relevant aspect. This is shown to hold for typical operations in a variety of practical situations. To better grasp the inherent power of twin grid files, variations of crucial parameter settings are studied in detail.

,Using graphical information from a grid file’s directory to visualize patterns in Cartesian productsing as they apparently lack a common ground. By example of a region directory, a particular directory for the grid file, we show how an elementary measure, namely data density, can usefully serve data management and data visualization by providing the basis for a common structure. The region direct

Twin grid files: A performance evaluation,tilization, even for independently and uniformly distributed points. We evaluate the performance of two types of space optimizing access schemes, the optimal static and the suboptimal dynamic twin grid files. It turns out that in comparison with the (standard) grid file, twin grid files achieve cons

,Internal and external algorithms for the points-in-regions problem — the INSIDE join of geo-relatioeprocessing is allowed. This problem arises in geometric database systems. More specifically it is equivalent to computing the . join of geo-relational algebra, a conceptual model for geo-data management. We describe efficient algorithms for solving this problem based on plane-sweep and divide-and-c

Geo-relational algebra: A model and query language for geometric database systems,emantics, expressive: allow to express with ease all desired query and data manipulation task, efficiently implementable..To achieve these goals we propose to extend relational database management systems by integrating geometry at all levels: At the conceptual level, relational algebra is extended
