The Construction And Application Of The Urban And Rural Integrative Model Of The Modern Cadastral

This paper is the generalization of theories and technologies based on several urban and rural integrative modern cadastral information systems practices. With the development of our economy, the gap between the urban and the rural has been narrowed. The urban and rural disjunctive cadastral model has showed its shortcomings in numerous aspects. In the vast developed area especially whose little towns were greatly developed, the bureau of cadastral look urgently forward to use a unified model to administrate the urban and rural cadastral, and implement the integrative cadastral management.After the researches on several cadastral information systems and the references to relative technologies, rules and the new developments in relative fields , this paper bases on several key technologies of the urban and rural integrative cadastral management, and puts forward the meaning and purpose of itself.The main body of this article begins at the lacks of the urban and rural disjunctive cadastral model, and then presents a series of problems that the urban and rural integrating cadastral faces, and then analyses these problems one by one. Based the spatial concepts of cadastral feature, this paper abstracts the urban and rural cadastral objects and discusses the relationship among them. After this the paper extends the concepts of the established cadastral management cells, and presents "general block" and "general land parcel". Based on them it presents the urban and rural integrative cadastral model. Based on the model and combined with Geodatabase of ESR1, this paper discusses the design of the urban and rural integrative cadastral database. At last the urban and rural integrative modern cadastral management information system of Jiangyin is recommended in order to introduce the application of the model and design that this paper has presented.The innovation of this paper can be explicated as the following:First, based on the spatial concepts of cadastral feature this paper presents "general block" and "general land parcel".Second, based on "general block" and "general land parcel" this paper presents the urban and rural integrative cadastral management model, and then combined with Geodatabase it introduces design of the urban and rural integrative cadastral database, and based on this the urban and rural cadastral data can be stored in the same database by the same way.Third, based on the first and the second the author designs and constructs a successful instance, the urban and rural integrative modern cadastral management information system of Jiangyin, and then this paper presents the methods to classify the cadastral data by layers and the feature coding in the urban and rural integrative cadastral system, the method to administrate the user's privilege in the urban and rural integrative cadastral system, the method to output the production in the urban and rural integrative cadastral system, and the method to update the cadastral data in the urban and rural integrative cadastral system.
