[Termes IGN] Pékin (Chine)Résumé : (Auteur) We developed a CA-based urban growth simulation model to emulate the city growth before 1997 and simulate possible change scenarios after that. An adaptive Monte-Carlo method was used to automate the calibration of factor weights used in the CA transitional rules. We used one scene of Landsat MSS imagery from 1975 and three scenes of TM imageiy from 1984, 1991, and 1997 to classify the land-use patterns, and we used the results to calibrate the CA model. We applied the model to assess the general urban development plan entitled "disperse polycentric urban development plan" of Beijing City and found that the plan failed to meet its objectives.

[Termes IGN] utilisation du solRésumé : (Auteur) This paper presents a new method to simulate the evolution of multiple land uses based on the integration of neural networks and cellular automata using GIS. Simulation of multiple land use changes using cellular automata (CA) is difficult because numerous spatial variables and parameters have to be utilized. Conventional CA models have problems in defining simulation parameter values, transition rules and model structures. In this paper, a three-layer neural network with multiple output neurons is designed to calculate conversion probabilities for competing multiple land uses. The model involves iterative looping of the neural network to simulate gradual land use conversion processes. Spatial variables are not deterministic because they are dynamically updated at the end of each loop. A GIS is used to obtain site attributes and training data, and to provide spatial functions for constructing the neural network. The parameter values for modelling are automatically generated by the training procedure of neural networks. The model has been successfully applied to the simulation of multiple land use changes in a fast growing area in southern China.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) Geographic information systems (GIS) were introduced into China (Mainland) in the 1970s. This paper provides an overview of the advances in GIS in Mainland China (not including Taiwan, Hong Kong, and Macau) during the post more than 20 years. It covers the developments of operational application systems, national geospatial databases, and technical systems. It also reviews the advances in research, education, and institutional development.

[Termes IGN] VRMLRésumé : (Auteur)Distributed virtual environments (DVE) are environments that ore not only used for managing and delivering m multi-source, multi-dimensional, geographical information, but also enable geographically distributed users to navigate in a 3D space, and to interact with objects and with other online users. In this paper, we design DVES to disseminate 2D and 3D data and to implement public participation in the management of the country parks in Hong Kong. The system framework, geo-data model, and user's interface are discussed for designing DVES. Based on the Virtual Reality Modeling Language (VRML), Java, and VRML External Authoring Interface (EAI) classes, a balanced client/server architecture is employed. In view of multi-source and multi-dimensional data, the object-oriented approach is utilized to design 3D geo-object models for web-based distribution. Considering the Internet bandwidth and performance of client computers, we adopt multi-block and multi-level approaches to the design of 3D geo-objects. The user's interface provides capabilities for implementing 2D and 3D view, data query and analysis, object addition/removal, and 3D avatar-based and text-based communication. This paper presents a case study of the Shing Mun Country Park in Hong Kong, where a prototype DVE, called "VirtualPark", was developed.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) There are three requirements for improving the efficiency of a collaborative decisionmaking process. They are (1) an agile communication and interactive methods, (2) reliable information, and (3) effective processing and visualizing tools. The GISbased Computer Supported Collaborative Work (CSCW) system is a powerful assistant for achieving these requirements. It has been successfully applied to the Urban Planning and Land Administration Bureau of Changzhou Municipality in Jiangsu Province. This paper presents the method used in developing the CSCW system, which has been in operational use since 1997. With the assistance of the system, the efficiency of collaborative decision making has been significantly improved by reducing duplication of effort, minimizing redundant data collection and analysis, and maximizing information sharing. More reasonable decisions have been made based on the integrated information from the federated database and various analysis tools. The Bureau has become more "just and open," as the public admits. Some suggestions for further work are discussed.
