Study On Theories And Application Of Urban Spatial Information Engineering

Based on the investigating and practice, and the principle of data dynamic stability and information shearing, an approach on theory and application of urban spatial information engineering is made with the guidance of conception and methods of engineering system management, supporting by the 3S and the computer network technologies. The emphases are establishing an integrative technical flow of urban spatial information engineering, a dynamic stable flowing mode of framework-database and a shearing flowing mode of urban spatial information by means of application and problem-oriented so that a system frame of theory, method, technique and application of urban spatial information engineering has installed primarily. The key contents are included as below:1. the significance put forward of urban spatial information engineering, the analysis on some exiting problems, the evaluation the developing direction of surveying to spatial information science and the means, system and course of study;2. the theory exploration of urban spatial information engineering by using of spatial philosophy and methodology, the collective construction policy in the property of staging, betimes and permanence in the engineering;3. the dynamics process mechanism of urban spatial information system and the dynamic stable flow mode of framed-database by basing on the systematic dynamics principle and method, the analyzing on process mechanism of urban spatial information system and the establishing of dynamic stable flow mode of framed-database.4. the shearing method of urban spatial information and the shearing mode and ensuring system in organization, management and technology based on systematic dynamics and parallel process principle;5. the practice in urban spatial information engineering, the design on integrative technique flow of spatial information engineering and the conclusion about the theory and technical results for urban spatial information infrastructure.
