The Design And Implementation Of Integrated Management Subsystem For Remote Sensing Users

With the rapid development of satellite remote sensing technology,remote sensing technology has been widely used from the initial military field to the current civilian areas.Domestic and foreign industries and scientific research institutions have gradually gained and accumulated a large amount of remote sensing data,in order to meet the data needs of industry users and realize the sharing of remote sensing data fusion,Scientific Information Service Platform came into being.This paper combines the comprehensive management of scientific information service platform to carry out relevant research.Scientific information service platform is the portal of remote sensing information product production platform,and it is the carrier and working platform of the internal and external information exchange.This platform involves a large number of users,so we must develop an integrated management subsystem which includes user management,log management and task management for remote sensing users to achieve centralized and efficient system management.The main work of this paper is as follows:(1)In terms of system user rights,taking into account the scalability of the system,the role based access control(Role-Based Access Control,RBAC)model is used to maintain and manage the relationship between users,roles and permissions.(2)In terms of log management,the system realizes the record of system log information and controls the level of log information,output,record time,output format and so on.Log management supports retrieval words used in conjunction with “and” or “not”,and implements custom retrieval,classified view and regular cleaning.(3)In terms of task view,according to the completion of various tasks and tasks submitted by system users,the system provides a visual retrieval interface which is convenient for users to view the task of implementation.It also supports setting diverse retrieval conditions and querying target tasks.Through the research of the above work,this paper uses C/S mode,Java programming language and MySQL database to design and implement a visual centralized management system for remote sensing users.Through the actual application of the system,this system meets the design requirements and achieves the desired results.
