Abstract
Some embodiments of the invention provide a method that computes an estimated distance between an external point and a set of points in a region. This method initially identifies a non-Manhattan polygon that encloses the set of points. It then identifies a distance between the external point and a point on the boundary or within the first non-Manhattan polygon. Finally, it uses the distance to identify the estimated distance.
