Abstract

Public participation in the planning of great significance. On the one hand, the general public, especially for Planning and residents, for planning decisions to bring important information on local conditions (including historical background, social and cultural, geographical, and other information), these valuable information is often involved in planning experts can not be fully equipped. On the other hand, so that more members of the public to participate in the planning of their own living environment can effectively enhance the sense of belonging to the citizens, increase public satisfaction. There are many ways of public participation in the planning. Depending on the type of public participation in the planning activities, the public participation can be divided into two types: the way of the evaluation and design. In the evaluation, the public is mainly to express their views on the existing plan; design, public planning design and modification. Both compared to the participation of the evaluation is mainly aimed at the general public, and the design of participation is more focused on the public with some professional background and relevant experience. With advances in technology, media and tools to support the above two modes of participation are also changing. For the evaluation of participation, the public no longer need to use paper correspondence, but can express their evaluation on the project plans via email or website. Gradually replaced the traditional drawings and pencil for the participation of the design, geographic information systems and computer-aided design tools, so that the public can more easily design plan. In addition, in both public participation in the planning, 3D visualization technology is increasingly used in the display of the plan, in order to help the public more intuitive understanding of the visual effects of the program. However, the existing support public participation in planning tools and systems there are two shortcomings. First, although many systems can use three-dimensional scene to show planning program, but also allows the public via the Internet on the program design or reviews, but these systems does not make public in different locations via the Internet in the three-dimensional scene together planning and design. Secondly, many systems and not the evaluation and design of both public participation in the planning and effective combination. Since the evaluation and design for a different group of the public, if you can not be active at the same time support both participatory approach, we will not be able to fully collect the views of the public. This design has a support public participation in the planning of the three-dimensional GIS. The inadequacies of the above two points has been improved. First, the Virtual Earth technology, Internet technology, socket technology and multi-threading technology combined participants (including public and experts) planning in different locations via the Internet for collaborative planning and design in the three-dimensional scene . Second, the system uses the Gemini system (discussion of program design subsystem and program evaluation subsystem) mode effectively combine the two public participation in the planning up. Discussion of program design subsystem so that the public has a professional background and planning experts and remote work together and design a draft plan; program evaluation subsystem draft is planning to publish show for the public to browse and Reviews. The twin mode can take to collect the views of the public, thus better supporting planning decisions. This paper describes the design ideas and methods of the three-dimensional GIS, and through a hypothetical case illustrates how the system is to help the public and experts in different locations in the three-dimensional scene collaborative planning, and how to effectively support the design and evaluation of both public participation in the planning.
