摘要
以3S集成技术为基础,面向水利应用服务给出1个水利数字地球基础平台的构建方法,解决GIS信息融合、影像金字塔构建等问题,构造1个具有互操作能力的一体化应用服务环境,完成对水利业务数据的进一步直观展示,并在调水移民工程的信息管理系统中加以应用,为水利信息化中数字地球技术的应用及虚拟现实平台建设提供一定的可借鉴经验。
Based on 3S integration technology, a construction method of hydrological digital earth basis platform was put forward oriented to hydrological application. The method solves the problem of GIS information fusion and image pyramid construction, establishes an integrated application service environment with interoperability, complements further visualization of hydrological business data, and applies in MIS of resettlement and immigrant project of water diversion, which provides some experience for application of digital earth and construction of virtual reality platform in water information.
