Zusammenfassung
The line simplification problem is an old and well studied problem in cartography. Although there are several algorithms to compute a simplification there seems to be no algorithms that perform line simplification in the context of other geographical objects. This paper presents a nearly quadratic time algorithm for the following line simplification problem: Given a polygonal line, a set of extra points, and a real $\epsilon > 0$, compute a simplification that guarantees (i) a maximum error $\epsilon$; (ii) that the extra points remain on the same side of the simplified chain as on the original chain; and (iii) that the simplified chain has no self-intersections. The algorithm is applied as the main subroutine for subdivision simplification and guarantees that the resulting subdivision is topologically correct.
