| In recent years,with the rapid development of informationization and networking,Shared thinking has become a hot and cutting-edge concept.In surveying and mapping geographic information industry,we should learn from the Shared thinking mode,and the space geography data should be Shared with everyone in the premise of ensuring information security.In view of the problem of geographic data sharing,the WebGIS provides a good solution.Global land cover data includes rich geographical knowledge and ecological change rules,it is a geospatial data with significant value.From the point of view of data sharing,this paper designs and implements an online statistical mapping system based on the global land cover data.during the process,the paper discusses and analyzes the online raster data real-time processing of related technology and Web graphical technique based on statistical data.Meanwhile,combined with cartography theory and method,the online statistical cartography system is realized.Finally,in order to solve the problems of high concurrency and load balancing,the public cloud platform was introduced,and the cloud deployment of online statistical cartography system was explored.This paper firstly makes a detailed systematic analysis,and based on the analysis results,the development framework based on B/S architecture is adopted as the overall framework of the system.then,The detailed system development and implementation technical proposal is designed.using the technical proposal.On this basis,the whole system is constructed by using the corresponding development language.At last,it successfully completes the deployment of aliyun platform of the system and discusses the dynamic expansion based cloud platform. |
