The modeling of large-scale vernacular houses in South-east China is a challenging work. In this paper, we implement an urban modeling system, using a production-based recursion grammar system to generate all the vernacular houses and the arrangement of the urban district. This grammar system is found on the basic elements of the vernacular houses' components, such as windows, gates, walls, roofs etc, which is regarded as a term in productions. Furthermore, to avoid the disadvantage (hard to control) of the grammar system and to ensure the coherent architecture styles of ancient vernacular houses, we also design a verifying system, which can check out those invalid house combination and regenerate them.
Most of the current popular GIS software only has solved the connection between the static data and map data in landscape planning and evaluation, but they seldom concern that the time plays a very important role in the landscape planning and evaluation system. In this paper, according to the multi-hierarchical dynamic property existing in the landscape planning and evaluation system, a concept of dynamic interaction is introduced, a kind of three-dimensional dynamic GIS model for landscape planning and evaluation system (it is named 4D-GIS-Model) is proposed, methods for the realization of the system based on this model are discussed, and a simple application of this dynamic GIS model is given finally.
