Design And Implementation Of Geological Interpretation Spatial Database Based On IRP

With the development of Geographic Information System technology and the continuous improvement of the data collection method.GIS combined with geological industry for business processing of geological industry has brought great convenience,at the same time also produced a large number of spatial data in the practical application.Spatial data is the core of GIS application,it carries on the effective management of spatial data is becoming more and more important.At present,spatial information resources construction,management and application of the remain independent,lack of unified planning and standards,low level of spatial data sharing,unable to realize unified management problems such as spatial data,eventually lead to can't for comprehensive utilization of existing spatial data information and intelligence analysis.Information resource planning(IRP)can process data and use of resources in a reasonable manner,the purpose is to increase the utilization level of information.From industry by information resource planning can be highly overall planning data storage,and the development and utilization of information resources,improve the utilization efficiency of data,effectively reduce the data redundancy and the maintenance cost of the data.It is based on the information resource planning theory has the advantage of data management,to solve the problem that create your own data and use them.In this paper based on the theory of information resource planning put forward design of remote sensing geological interpretation spatial databaseThis article based on the theory of information resource planning of subject database put forward the geological interpretation subject database.On the basis of geological interpretation industry business classification divide the different themes.According to the national standards of geological interpretation industry decides each type contains data.Enterprise Architect software build theme database,to ensure that data has a unified standard and good interoperability,so as to improve the level of sharing.The general data programming model of information resource planning put forward the remote sensing geological interpretation different database,such as the subject database,the business database,the results database,the achievements data pool and design the conceptual model,logical model and physical model of each database.According to geological interpretation of the overall data programming model is put forward data sharing function module,data portable function module,data scalability function module and data scalability function module,implementation and the corresponding functional modules.
