This situation has more the existing ring road with crossing at many highways, and as shown in Figure 5, a part (D51 part) of highway D5 is passed under highway D6, and another part (D53 part) passes on D6.
So in the embodiment of the present invention, the hierarchical identification in the coordinate information of two affiliated respectively for D51 and D6 crossed nodes can be arranged to different numerical value or symbol, be that mark D51 and D6 intersects but is not communicated with (also can be used for mark D51 under D6).Meanwhile, also the hierarchical identification in the coordinate information of two affiliated respectively for D53 and D6 crossed nodes can be arranged to different numerical value or symbol, be that mark D53 and D6 intersects but is not communicated with (also can be used for mark D53 on D6).
So when road network is played up, the road network that first can carry out D51 place layer is played up, and then carries out playing up of D6 place layer, finally carries out playing up of D53 place layer.
Because section D52 is only connected with section D51 with D53, but non-intersect with D6, and therefore, section D52 can play up with layer with section D51 or section D53, also can play up with layer with D6.
