Design And Implementation Of One-stop Management Platform For Surveying And Mapping Data Archives

Surveying and mapping data archives have many sources,complex structure,large amount of data,and large spatial location data also show exponential growth.Efficient management of Surveying and mapping data archives is a technical problem that managers have to face.In view of the above problems,this paper designs and implements a one-stop management platform for surveying and mapping data archives.The main work is as follows:(1)The whole stack system framework is designed,including user layer,suite layer and data layer.Suite is a modular unit that can be assembled flexibly in the suite layer.The design of the suite layer supports the efficient and flexible assembly of functional modules,improves the scalability and scalability of the system,realizes the loose coupling of the system architecture,and supports the reusability,flexible combination of functional modules and the extensibility of the system.(2)Based on the OAIS reference model,a reference model framework for long-term preservation of data and information,and combined with the actual business processes of Surveying and mapping units,the relevant functional modules of the surveying and mapping data archives management platform are designed,which realizes the integrated management of the access and access of Surveying and mapping data archives.(3)The spatial data organization form based on geographic blocks is designed."Geographic Block" is a continuous division of geographic space according to certain principles,forming a grid unit.Aiming at complex spatial data with data structure,the "Geographic Block" is adopted as the basic geographic unit to realize the integrated organization and efficient management of large-scale,multi-source and heterogeneous geographic information,such as image,three-dimensional model,especially unstructured geographic information.(4)A one-stop management platform for surveying and mapping data archives has been developed,which realizes one-stop management for data archives access,data browsing,update and inspection,query and statistics,and record backup,and has been applied in practice.
