The evolvement of hardware technologies leads the growth in development of Geographical Information System (GIS) applications that represent the geographic space in a digital environment. The conventional GIS are unable to handle the complex nature of the spatial data. Migration and transition from 2D to 3D emerge some problems in order to construct robust GIS applications. Two core obstacles, that is, database management and fast real-time visualization are main difficulties that encounter nowadays. However, the performance of data operation on the huge multi-dimensional database is still a difficult subject, especially involve in real-time visualization. Users and developers perspectives have to be considered and fulfilled in order to remedy the problems. A number of researchers have proposed their own optimization algorithms, techniques and approaches which attempt to reduce the complexity of the problems. A survey has been made to review the current issues related to the development of 3D Virtual GIS.
