摘要
近年来,地理空间大数据引起了产学研及政府部门的高度关注,甚至引发了许多变革。面向电子政务的地理空间大数据技术为政府信息管理和决策提供了新的手段。本文在阐述政务地理空间大数据的内涵及特点的基础上,重点梳理了政务地理空间大数据处理的关键技术,包括政务地理空间大数据整合、存储与管理、挖掘与分析、可视化以及决策支持服务技术,最后分析了当前和未来政务地理空间大数据所面临的机遇和挑战。
In recent years,geospatial big data have attracted great attention from industry,academia,research and government sectors,and even have triggered a lot of industry changes.Geospatial big data for E-government provide new means for government information management and decision making.This paper analyzes the concepts and characteristics of geospatial big data for E-government,mainly reviews the key technologies in geospatial big data for E-government,including data integration,storage and management,data mining and analysis,visualization,and decision support service technologies.Finally,the bottleneck problems and technical challenges of geospatial big data for E-government are discussed.
