The VWorld Data Center of South Korea provides the latest high-definition 3D national spatial information. In this paper, we propose a 3D terrain object generation method using VWorld data. A tile-based 3D map has gap problems when elevation change is large like mountainous terrain. Since different level tiles are adjacent to each other, the elevation of boundary of tiles does not match, resulting in empty space or the border area are exposed between tiles. Our proposed method considering the characteristics of tiles provided by VWorld Data Center enable to minimize gaps between tiles. We enable to minimize gap problems by making the size of the outer cell equal to the adjacent high-level tile. We describe the 3D terrain generation method and experimental results. The proposed method could be used on other tile-based 3D map platforms.
