....apply immediately to any other type of object represented by a simplicial piecewise linear complex. For example, given two local planar straightline graphs, we can overlay them in O(n log n) time either by using the standard sweep line algorithm, or by merging a graded (semi )R tree for each graph [5, 27]. Similarly, given two local finite element meshes, we can find all pairs of overlapping elements in near linear time using recursive bisection. In particular, this technique is e#cient for the well shaped meshes produced by Delaunay refinement algorithms. These and other algorithmic applications ....

In Section 6.2 we will give experimental results on choosing # # . 4.2 Finding Object Pairs within # # We want to find all those object pairs whose new distance is within this new threshold # # . Similarity joins over multidimensional spaces have been studied in [1, 6, 9, 21, 22, 24, 28, 33, 32]. Many algorithms can be used in this step. In this paper we use a simplified version of the algorithm in [16] as an example. We could instead have chosen any of those algorithms for our purpose. We chose the algorithm in [16] due to its simplicity and availability of the code. This approach ....

....case. A lot of work has been done on 2 way spatial joins. Most previous work focused on joins with the predicate region intersection. The intersection spatial join algorithms can be roughly divided into two categories: ones that use spatial index structures and ones that do not. Algorithms of [BKS93,HJR97] use spatial index structures such as R trees, R trees, R # trees. Interval B trees [ZSI99] and external segment trees [Arg95] can also be used. Algorithms without using index structures were reported in [PD96] LR96] and [APR 98,Vit98] PD96] and [LR96] used a partition based ....

....queries involve two or more (see e.g. 9] sets of spatial data and combine pairs (or tuples) of spatial objects that satisfy a given predicate. For instance, one might be interested in finding all the pairs of objects that intersect with each other (intersection join) Brinkho# et al. present in [10] a very detailed analysis of di#erent implementation strategies for an intersection join. They show that a spatial sort merge based join based on a plane sweep technique outperforms a nested loop one. However, the plane sweep technique proposed for an intersection join cannot apply for the purpose ....

....performs a spatial join on approximations of the objects; and (2) a refinement step that checks whether the objects discovered by the filter step actually intersect. A great deal of research has been done to speed up the filter step and to reduce the size of the result it produces. Many algorithms [16, 18, 17, 20, 3, 7, 1, 19, 22, 15, 11, 2, 25] focus on the filter step and use the minimum bounding rectangle (MBR) the smallest rectangle containing a spatial object, as an approximation of the object. In this paper, we call these algorithms rectangle join algorithms. Rectangle join evaluation has been the focus of the study on spatial ....

The algorithm in [20] uses join indices [24] that are actually partially precomputed join result.
