description A navigation system (NS) may include a processor that can retrieve geographic map data from a database, where the geographic map data includes polygonal chains. The processor can determine a straightness value, a length ratio, and/or an angle-to-length ratio for each of the polygonal chains based on segments and/or vertices of the polygonal chain. Also, a first class and a second class of the polygonal chains can be determined based on one or more of the three determined values for each of the polygonal chains. The first class may represent roads that are less winding than the second class, and such an attribute may be beneficial in selecting an optimal route.
