- Abstract
- Rep. of Korea's Ministry of Land, Infrastructure and Transport provides the high-quality 3D spatial information such as aerial images, digital elevation models or 3D structure models through the VWorld data center. This paper proposes a quadtree-based 3D spatial information open platform based on WebGL. WebGL is a web-based graphics library and has the advantage of being compatible with various web browsers. We performed the visualization of 3D spatial information with the quadtree data structure according to the characteristics of the VWorld data model. Therefore, the large amount of national spatial information data can be effectively displayed according to the position and direction of the camera position. We also provide an executable site for implementation of the proposed 3D open platform.
