Legacy application systems have been widely used by user communities, and by individual users. They are currently providing a variety of functions required by system development requirements. For the development of a new 3D system using such legacy systems, we need both (i) the migration of legacy systems into a new 3D system environment, and (ii)(More)
There is an increasing demand for 3D geographic simulation systems. Most systems currently available are closed and based on fixed architectures. Some systems allow us to develop and customize a 3D geographic simulation system, but this usually requires the writing of extensive program code. Especially in 3D geo-disaster simulations, for example, we need to(More)
