态势感知在灾害响应和应急管理中发挥着重要作用。在灾难事件中显示实时的基于位置的社交媒体信息以及视频、图片和标签，可以帮助急救人员提高他们的情况意识。开发了一款地理定位事件观察（Geo） Viewer，用于实时监测目标区域的社交媒体信息，主要有四个功能：(1)实时显示目标区域内的地理标记推文；(2)交互式映射功能；(3)使用关键词、空间边界或日期的空间、文本和时间搜索功能；(4)信息的人工标注和文本标注。与传统的web GIS地图不同，GeoViewer的用户界面设计提供了多媒体内容和地图的交互显示。可视化和查询tweet的前端用户界面是用使用服务器端MongoDB的开源编程库构建的。GeoViewer旨在通过跟踪灾害事件的影响、恢复活动和目标地区居民的需求，协助应急响应和灾害管理任务。
Situation awareness plays an important role in disaster response and emergency management. Displaying real-time location-based social media messages along with videos, pictures, and hashtags during a disaster event could help first responders improve their situation awareness . A geo-targeted event observation (Geo) Viewer was developed for monitoring real-time social media messages in target areas with four major functions: (1) real-time display of geo-tagged tweets within the target area; (2) interactive mapping functions; (3) spatial, text, and temporal search functions using keywords, spatial boundaries, or dates; and (4) manual labeling and text-tagging of messages. Different from traditional web GIS maps, the user interface design of GeoViewer provides the interactive display of multimedia content and maps. The front-end user interface to visualize and query tweets is built with open source programming libraries using server-side MongoDB. GeoViewer is built for assisting emergency responses and disaster management tasks by tracking disaster event impacts, recovery activities, and residents’ needs in the target region.
