This paper introduces an interactive browsing system that efficiently supports the reliable distribution of 3D GIS data including 3D urban models with texture, attributes and aerial/satellite images. Our approach uses the view-dependent simplification to reduce the number of primitives distributed and rendered. We apply to make preparations for only visible primitives concerning with each 3D viewpoint and direction in advance. This approach will make it possible to distribute only the visible data, that is, no occlusion culling in rendering. Additionally, we suggest a compression concept to control the increase in the supposed view sets. Experimental results show that our approach is stable and reliable enough to make the distribution and rendering of 3D GIS data possible.
