VWorld Data Center (VDC), operated by the Ministry of Land, Infrastructure, and Transport of South of Korea, provides the latest high-quality spatial information of South Korea. VWorld data include aerial images, digital elevation models, 3D buildings, 3D bridges, roads, administrative information, etc. We present a 3D spatial information platform that uses VWorld data. This platform is based on the web browser environment and supports cross platform by complying with WebGL and web standards. The 3D-terrain tile structure has a quadtree-based detail level for high-resolution rendering. When rendering different tile levels or sizes simultaneously, abnormal gaps occur between the tiles. We propose the use of a specially shaped 3D terrain object model to minimize these gaps. This model can be used and verified using the service site of the WebGL-based VWorld spatial information platform. Our platform has a limited environment and runs in a web browser while requesting real-time spatial information data from VDC. VWorld data cannot be stored locally by policy. We improve the frame rate in such way that it can easily be used in a limited web browser environment or even a computing environment without a graphics processing unit. We intend to officially present the proposed method to the VDC and apply it. We expect our platform to be used for various web-based geospatial applications.
