The Research And Design Of The Land And Resources "One Map" Central Database Of Yunnan Province Based On Information Resource Planning

With the rapid development of land resource Information construction in Yunnan Province, the Yunnan Provincial Department of land and resources has accumulated massive valuable land resources data, including a large number of basic surveying and mapping data, thematic data and mineral resources environmental data. But because the source of these data is different, some data are in different formats, the data storage location is dispersed, some of these data have already been in existence for a long time, and some of these data has no uniform standards when build the database, all these reasons lead to a very complex data situation. Multi-sources, multi-formats and multi-scales data seriously affected their comprehensive analysis and application, so it is difficult to play their great value. It is urgent to resolve that how to integrate disperse land resource information in order to sake of managing decision-making service, and provide network service. Therefore this paper started from formulating relevant standards, choosing the Information Resource Planning method to analysis, induce, integrate, storage the massive, multi-sources and heterogeneous different categories and professional data around land and resources application of demand management and the actual situation, building standardized data updating and sharing mechanism, and at last build the land and resources "one map" central database of Yunnan province.This paper first made a research on the current situation of land resources information construction of Yunnan Province, combed the existing land resources data and information management system. Then established standards of land resources data of Yunnan province according to the national standard, the provincial standard and the industry standard; Referencing to the standards, integrate the land resources data of Yunnan Province, turn the integrated Multi-source, multi-scale and multi-period data into an unified standard data resources. Using the method of Information Resource Planning to top-down comb land business processes based on the practical application and the demand of the administrative management and complete the data flow diagram, using the method of Enterprise Architecture to design the framework model of land and resources "one map" central database of Yunnan province, and then put the integrated data into the database and build standardized data updating and sharing mechanism for supporting all other information system of land and resources. Finally, take the E-government system of Yunnan Province as an example to indicate that the central database is how to provide good data support.To sum up, this paper based on fulfilling the management of the actual application of land and resources of Yunnan Province as the main line, through analysis the existing land resources data, propose the standards of land resources data of Yunnan province, and using the top-down design method to build the database, using the method of Information Resource Planning to model the land resource data, finally realization the construction of the land and resources " one map" central database of Yunnan province, and has practical significance for promoting information construction of land resource.
