PURPOSE: A 3D link storing method of a navigation and a matching method thereof are provided to match a link to enable a road link line to be accurately corresponded with a modeled 3D link line by generating a link which is suitable for 3D modeling. CONSTITUTION: A road link of map data suitable for 3D link is generated(S210). A specific point longitude and latitude coordinate value of the road link, which is corresponded with a starting point of the 3D link is extracted(S220). The extracted road link longitude and latitude coordinate value is saved with a 3D link ID(S250). The road link of the map data is implemented two-dimensionally. The road link longitude and latitude coordinate value is used as the intrinsic link coordinate. |
