Abstract

To design and implement web-based 3D GIS, the strategic linkage of Java and VRML is first regarded: 3D feature format definition in the passion of conventional GIS including aspatial attributes, 3D feature indexing, 3D analytical operations such as selection, buffering, and near, metric operation such as distance measurement and statistical description, and 3D visualization. In 3D feature format definition, the following aspects are considered: aspatial attributes, spatial information for 3D primitives, multimedia data, visualization information for VRML specification. "Lantern operator" is newly introduced in this 3D GIS. Because this system is implemented by Java applet, any client with Java-enable browser including VR
