Land Resources Integrated Management System Data Service Module Research And System Design

"Digital city" is an important development direction of social informatization construction,city building "digital city" geo-spatial framework of the root is established in time and space information data in the data resource sharing unicom technology system interaction and service.As an important national situation,the data of land elements is in a particularly critical position in the course of economic development and social progress.In the years of land and resources management business,it has accumulated a large number of data resources including mapping geographic information,land use data,geological conditions,mining mineral status and satellite image.Because the business system of the municipal bureau of land and resources was built at different times,it is only for each department's own daily work service,lack of interconnection.The system construction is not carried out according to the unified standard and standard,the business system is isolated and developed,the data is not matched,the interface is not interrelated,and the data quality is not compatible with each other,and it is difficult to realize the sharing.In the context of the national planning and construction of the big data platform of land and resources,the elimination of "information isolated island" is the first problem to solve the aggregation and sharing of data in the industry.The thesis put forward according to the construction of "digital changzhi" geo-spatial framework as an opportunity to set up based on the network service in the form of the data resource sharing solution,research designs and implements a "digital changzhi comprehensive management information system of land and resources".Will "digital city" of basic geographic information database,and the department of all kinds of business system data,through the service module,data conversion for the OGC standard web services,loading guide system,to realize data aggregation and unified management.All data requests through the system of the data service module,eliminate the data integration between the business system and affect a lot of work,to reduce data integration,other business application system data reconstruction can be ignored and so on,and the data access services need to be based on their data.
