SGER: Addressing the Data Management Challenges of Disaster Information Management Within the Context of a Pilot National Data Center (NDC) for Sri Lanka

2004年12月26日的苏门答腊-安达曼地震和随后的海啸导致了两个关键情景的发现。印度洋沿岸的政府部门国家内部缺乏信息管理系统。在全球范围内，还没有能够处理各种灾害信息管理需求的灾害管理软件。这个项目在Sahana的背景下探讨了数据管理的智力挑战，Sahana是一个开源的灾害信息管理系统，在灾难发生后几天内就在斯里兰卡部署了。第一个挑战是灾害信息管理数据管理部分的设计。虽然数据库设计不是一项挑战，但理解灾难期间和灾难后应该访问的信息的范围是一项挑战。第二个挑战是斯里兰卡国家数据中心范围内的数据获取、数据清理、整合和质量计划。虽然文献中报道了对类似挑战的解决办法，但斯里兰卡缺乏计算机化的信息管理系统，这使这项任务成为一项挑战。这个美国研究团队在广域数据库管理(Raschid)和开放源码开发和Web服务(Weerwaana)方面拥有专业知识。科伦坡大学计算学院(UCSC)的Karunaratne和斯里兰卡Moratuwa大学的Madurapperuma提供领域专业知识。通过开发开放源码的全球灾害管理系统和为斯里兰卡设计国家信息基础设施来满足产生更广泛影响的需要。项目网站http://www.umiacs.umd.edu/labs/CLIP/Handle/SGERtsunami.html将用于交流探索性项目和传播成果。

The December 26, 2004 Sumatran-Andaman earthquake and subsequent tsunami led to the discovery of two critical scenarios. There is a deficit of information management systems within the government sector countries on the coast of the Indian Ocean. Globally, there is no disaster management software that can handle a variety of disaster information management needs. This project explores intellectual challenges of data management, in the context of Sahana, an open source disaster information management system that was deployed in Sri Lanka within days of the disaster. The first challenge is the design of the data management component for disaster information management. While database design is not a challenge, understanding the scope of information that should be accessed during and after a disaster is a challenge. The second challenge is a plan for data acquisition, data cleaning, integration and quality, in the context of a National Data Center (NDC) for Sri Lanka. While solutions to similar challenges have been reported in the literature, the lack of computerized information management systems in Sri Lanka makes the task a challenge. This US research team has expertise in wide area database management (Raschid) and open source development and Web services (Weerawarana). Karunaratne from the University of Colombo School of Computing (UCSC) and Madurapperuma from the the University of Moratuwa in Sri Lanka provide domain expertise. The need for broader impact is met via the development of open source global disaster management systems and the design of a national information infrastructure for Sri Lanka. The project Web site http://www.umiacs.umd.edu/labs/CLIP/Handle/SGERtsunami.html is to be used for communication about the exploratory project and for disseminating results.
