We discuss in this paper a method of finding skyline or non-dominated points in a set P of n points with respect to a set S of m sites. A point pi∈P is non-dominated if and only if for each pj∈P, $j \not= i$, there exists at least one point s∈S that is closer to pi than pj. We reduce this problem of determining non-dominated points to the problem of finding sites that have non-empty cells in an additively weighted Voronoi diagram under convex distance function. The weights of the said Voronoi diagram are derived from the co-ordinates of the points of P and the convex distance function is derived from S. In the 2-dimensional plane, this reduction gives a O((m+n)logm+n logn)-time randomized incremental algorithm to find the non-dominated points.
