Workflow for Developing High-Resolution 3D City Models in Korea

Recent advanced 3D technologies have increased availability of 3D geospatial data. With this trend, new opportunities for creating geospatial-based realistic 3D digital contents are emerging. Among the various options, 3D city models are in particular demand from various domains. Many developed countries have transitioned from 2D to 3D city models including Korea. 3D city models using high-resolution geospatial information can be constructed simulating the real world by incorporating into them virtual reality or augmented reality. In this paper, we seek to understand the methodologies currently used to create 3D city models and present our planned research directions based on current trends. In addition, we briefly present our current implementation of Web 3D service (W3DS) according to the Open Geospatial Consortium (OGC) standards, as part of services essential to develop high-resolution 3D city models.
