Lecture Notes in Computer Sciencehe use for query processing of the proposed representation in conjunction with indexing. It is demonstrated how queries involving uncertainty may be answered using the standard filter-and-refine approach known from spatial query processing.

While both algorithms can reduce the amalgamation cost significantly, the occupancy-based algorithm is particularly attractive because: 1) it retrieves a smaller amount of data than the adjacency-based algorithm; 2) it is based on a simple extension to a commonly used spatial indexing mechanism; and 3) it can handle fuzzy amalgamation.

Algorithms for Joining R-Trees and Linear Region Quadtreesrent, access methods. Two of the algorithms are based on heuristics that aim at minimizing I/O cost with a limited amount of main memory. We also present the results of experiments performed with real data that compare the I/O performance of these algorithms.

Hojin Cho,Hyunjoon Lee,Seungyong Leend the paper provides a formal framework in which simplifications can be computed (for example, as compositions of other simpliffcations). A detailed case study is presented to illustrate the techniques developed, and directions for further work are discussed.
