The distance computation also finds a pair of points in the input geometries which have the minimum distance between them. If a point lies in the interior of a line segment, the coordinate computed is a close approximation to the exact point.
The algorithms used are straightforward O(n^2) comparisons. This worst-case performance could be improved on by using Voronoi techniques or spatial indexes.
