时空数据转换服务系统设计与应用

Design and Application of Spatio-temporal Data Conversion Service System

目前时空大数据的应用越来越广泛,但在非时空数据转换为时空数据时,存在人工依赖程度高、转换效率低等问题,且实现异构海量时空数据高效存储也是当前亟待解决的问题之一。通过重庆市时空大数据服务平台的建设实践,总结提出了4种时空数据转换模式;并通过研究流程转换自动化、时空大数据存储、时空大数据计算、时空大数据分析等关键技术,实现了从数据接入、转换、管理、分析、服务到数据应用的自动化全流程服务。

At present,the application of spatio-temporal big data is more and more widely,but in the process of converting non-spatio-temporal data to spatio-temporal data,there are many problems to be solved about high manual dependence,low conversion efficiency,spatio-temporal data big efficient storage.In this paper,through the construction practice of Chongqing spatio-temporal big data service platform,we summarized and put forward 4 kinds of spatio-temporal data conversion modes.And then,we realized the automatic whole process service consists of data access,conversion,management,analysis,service and application by studying the key technologies,such as process conversion automation,spatio-temporal big data storage,spatio-temporal big data calculation,spatio-temporal big data analysis.
