Descripción: Query imprecision may be frequently caused by the nature of many applications including location based services. The problem of capably computing range aggregates in a multidimensional space is examined in this paper when the query location is unsure. Specifically, for a query point P whose location is uncertain and a set X of points in a multi-dimensional space, we want to calculate the aggregate over the subset S of X such that for q each  ∈ S, P has at least probability θ within the distance γ to q.  Novel efficient techniques are proposed to solve the problem following the filtering-and-verification paradigm. Especially, to efficiently and proficiently remove data points from verification two novel filtering techniques are proposed
