Multi-source Geological Data Integration Based On ArcGIS Research On Management Method

Geological data is the main form of geological survey,and it is also an important carrier for geological work to serve the public,even an essential component of geological archive resources.Geological data is not only widely used in geological work in various fields,but also serves all aspects of economic society.Therefore,the rational development and utilization of geological data is conducive to the promotion of major breakthroughs in the field of geosciences,and has far-reaching significance for the development of economic and social services and the reduction of geological resources waste.In order to continuously promote geological data to give full play to its important role,save the cost of management,improve the efficiency of data management,and improve the service capacity of data,the relevant national departments has began to informationalize the geological data accumulated over a long period of time.At present,a large amount of manpower,material resources and financial resources have been invested in this aspect,and many scientific research and practical work have been done,and a series of research results have been obtained.However,geological data has the characteristics of large amount of data,diverse structure,and scattered storage,which hinders the development of geological data informatization to a certain extent,making it difficult for existing data management service capabilities to meet the growing demand for management services.From a broad perspective,geological data can be abstracted into multi-source geoscience data,and integrated management of geological data is the integrated management of multi-source geoscience data.At present,the main problems facing the current multi-source geoscience data integration management work is how to ensure the standardization of management methods,the centralization of storage methods and the efficiency of management platforms.To this end,this paper has completed the following research,firstly carried out feature analysis of multi-source geoscience data,and defined the essential characteristics of multi-source geoscience data from three aspects: data feature overview,data technology specification and data organization form,laying the data foundation for the design of its integrated management method.Secondly,according to the data characteristics,this paper put forword the multi-source geoscience data integration management method from the two dimensions of management process design and integration method design.This method solves the problem of data storage dispersion through ArcSDE,and at the same time,it designs and describes three processes of data processing specification design,data management platform construction and shared service data foundation.Each process has been strictly regulated to ensure the feasibility of the method.Then,according to the actual work needs,this paper carried out the overall design of multi-source geoscience data integration management platform,and it conducted the analysis from the construction of the platform architecture,the selection of key technologies,the establishment of the operating environment,and the design of the database 4 aspects,providing platform support for the integrated management of multi-source geoscience data with strong operability,good expansibility and easy interaction;finally,this method is applied to actual work,realizes the digitization of geological data,improves the data service capability,and solves the difficulties in the current geological data integration management process.
