Abstract:

National Development and Reform Commission declared that the eleventh five-year planning would put emphasis upon the spatial information integration. In regional planning, the spatial information is dynamic and complicated, so it is very essential that we should find an effective way to organize and manage all kinds of spatial information. Object-oriented method is a promising technology to help us with creating spatio-temporal data model, which gives us an idea to integrate the spatial information in regional planning. This paper suggests an object-oriented spatio-temporal data model for the spatial information in regional planning based on object-oriented theory and method; furthermore, it brings forward the definition and description of geographical feature classes structure. Object-oriented technology has comprehensive meaning in language, and it can express every spatial entity around us vividly and exactly. This spatio-temporal data model can inspect and record the changing of spatial information, so we can prosecute spatio-temporal analysis, forecast the development trend of regional economy, and establish reasonable implementary blue print in regional planning. Therefore, spatio-temporal data model is perfect in contrast with others.

Key words: object-oriented, regional planning, spatio-temporal data model
