【摘要】 破坏性地震发生后,利用获取的灾区遥感影像资料进行灾情判断,可以为地震应急和救援指挥决策提供重要依据。通常,遥感影像要经过复杂的制图、传输、打印等才能提供给应急指挥部门,降低了实效性。数字地球显示平台不但操作简单,而且信息显示丰富。本文提出利用遵循OpenGIS软件规范的开源WebGIS服务器和开源数字地球客户端构建地震应急遥感震害信息发布系统的解决方案,并以2012年云南昭通彝良地震为例,实现了GIS数据和遥感影像的在线发布和三维显示,结果显著提高了地震应急遥感震害信息的浏览显示效果,为应急灾情判断提供了有用的工具,在地震应急救援工作中具有重要的应用潜力。更多还原

【Abstract】 After a devastating earthquake occurs,damage extraction and loss evaluation from the remote sensing image data in the disaster area can provide an important basis for the earthquake emergency management and rescue mission.However,the remote sensing images must go through complex mapping,transmission,print works,before they are applied to the emergency headquarter.Digital earth platform is not only convenient,but can provide rich information to users.This paper provides a solution to build a system to share the remote sensing images acquired in the disaster area.The system is built with the open source digital earth platform and open source WebGIS server which follows the OpenGIS specification.It has successfully published the post-earthquake remote sensing images in the disaster area of 2011 Yiliang-Zhaotong,Yunan earthquake on the Web and display them in three-dimensional style with the digital earth platform,the example significantly improves the effect of displaying of the remote sensing images.更多还原
