Abstract:
With the development of the Internet, big data and diversification of mobile
terminals, based on the geospatial information of modern mapping, geographic
information systems, remote sensing, satellite navigation and positioning technologies.
The acquisition method, application mode and service direction of big data are
undergoing fundamental changes. Starting from the influence of big data on geospatial
information, this paper mainly discusses the change of geospatial information service
mode, interprets the connotation of knowledge service, and discusses the key strategies
for realizing knowledge service of geospatial information, so as to provide reference
for studying the deep application of geospatial information under the background of
big data.
随着互联网、大数据的发展以及移动终端的多样化,基于现代测绘和
地理信息系统、遥感、卫星导航定位等技术为基础的地理空间信息,其数据的
采集方法、应用模式及服务方向都发生着根本的变化,本文从大数据对地理空
间信息影响出发,主要讨论地理空间信息服务方式的改变,对知识服务的内涵
进行解读,并对地理空间信息实现知识服务的关键策略进行探讨,为研究地理
空间信息在大数据背景下的深层次应用提供参考。
