Research And Implementation Of Online Workflow Customizotion Of Remote Sensing Product Production Based On MxGraph

The National Medium and Long Term Planning for Civil Space Infrastructure(2015-2025)was officially released in 2015.According to this plan,the National Civil Space Infrastructure Land Observation Satellite Common Application Support Platform Project(hereinafter referred to as the "Space-based Project")will establish a national civil space infrastructure common application support system to meet the basic and common application support needs of the land observation satellites established by the National Civil Space Infrastructure Project.As an important part of the space infrastructure,the project will provide common and basic services and support facilities for the application of nine satellites deployed during the 12 th Five-Year Plan and subsequent satellites,effectively docking with different levels of applications,realizing common information product inspection,common technology evaluation and basic resources sharing of payloads of operational satellites and scientific research satellites,and providing remote sensing applications for satellites.Business Departments and Regional Applications Provide Business Services.In In order to meet the requirement of visual customization function of remote sensing product production in application technology sharing service subsystem,this paper designs and implements a workflow-based visual customization platform for remote sensing product production,and describes in detail the establishment of workflow model,the design of data structure of atomic algorithm,the specific method of realizing atomic algorithm componentization and visualization technology.(1)Research the use of mxGraph technology to make up for the shortcomings of traditional desktop process customization program in cross-platform.Traditional desktop applications based on C/S mode require users to download clients and install them before they can be used.If an upgrade occurs,all client programs need to be changed.The user's ease of use and cross-platform performance are poor,and the cost of development and maintenance is high.In this paper,we use mxGraph technology to solve these shortcomings on-line process customization platform based on B/3 slam design,and give the solutions of dragging and dropping of self-defined process atomic algorithm components,drawing of connection relationship,attribute configuration of algorithm components and generating custom process files.(2)According to the requirement of process visualization customization,the data structure and storage structure of atomic algorithm components are established.By analyzing the characteristics of the existing atomic algorithm and the data structure and storage structure of the basic workflow model,the corresponding data structure is designed for the atomic algorithm in the process of building the workflow model,which is prepared for the Componentization of the atomic algorithm,and the solution of the algorithm component and the flow belong configuration is proposed.(3)The application value and validity of this work are tested by applying it to practical projects.According to the requirement of online common basic service subsystem,the work done in this paper has been successfully applied to the visual customization platform of remote sensing product production process.The related research content of this paper has been verified.The practical application shows that the platform can effectively improve the customization efficiency of remote sensing product production process.
