The kth-order Voronoi diagram of a set of points in E2 (called sites) subdivides E2 into maximal regions such that each point within a given region has the same k nearest sites. Two versions of an algorithm are developed for constructing the kth-order Voronoi diagram of a set of n sites in &Ogr;(n2logn+k(n-k)log2n) time, &Ogr;(k(n-k)) storage, and &Ogr;(n2+k(n-k)log2n) time, &Ogr;(n2) storage, respectively.
