During the last decade, spatio-temporal database have become increasingly important in many application areas such as GIS, engineering information systems, CAD/CAM, remote sensing and environmental modeling. An important research issue in the field of GIS is the spatio-temporal analysis of huge geographical features with time such as buildings, roads, and so on. We propose a unified visualization framework for spatial and temporal analysis in 4D GIS. We also introduce a novel interoperable geographical data service concept; so-called, Virtual World Mapping (VWM) that can map 3D graphic world with real-world video. Our proposed method can easily retrieve geographical information in various views such as 2D, 3D views and videos. Our proposed system architecture also has an advantage that can provide video geographical information service without any processing such as frame segment trees construction and image segmentation.
