COSMOS Virtual Data Center

该行动支持COSMOS虚拟强震数据中心（COSMOS VDC）的持续发展，这是一个不受限制的、基于网络的、交互式的强震数据资源，适用于实践地震工程、应急响应、研究和其他地震专业社区。虚拟数据中心（VDC）的主要目标是扩大和显著改善越来越多的美国和国际组织收集的所有强震记录的可访问性和使用。VDC在强震观测系统组织联盟（COSMOS, www.cosmos-eq.org）的指导下运作，这是一个致力于地震安全的公益非营利组织。其使命是大大扩展强震数据的获取和应用，并使其现代化，以提高公众对地震的安全。COSMOS结构使VDC能够对收集数据的组织和数据的用户（学术和专业）做出响应，并确保VDC的发展，使其始终对工程师、科学家和其他强震数据用户社区做出响应。这一行动将通过进一步发展虚拟数据中心的成熟概念及其在协调强震数据的获取和传播方面的重要作用，提高COSMOS VDC的能力。它将：1)推进与先进国家地震系统（ANSS）数据管理系统的基于网络的接口；2)改进现有VDC元数据数据库的扩充方法；3)推进基于web的方法，促进对各种事件、站点和处理过的时间历史信息的高效查询和检索；4)根据用户可选择的格式、处理和可视化，开发基于网络的信息传播方法；5)促进发展COSMOS的数据格式和处理标准；6)改进与其他数据库的基于web的接口，以增强地震元数据、记录站点特征和VDC的其他相关信息；7)加强复制网站的网络界面和链接；8)推进基于web的岩土工程数据库接口。虚拟数据中心提供了一种极具成本效益的方式，以利用所有参与机构和组织的数据处理和管理资源。它在最先进的关系数据库中不断开发、更新和维护复杂的参数元数据环境。这一方法在改善研究、实践和应急反应界为减轻地震危害而获取数据方面向前迈出了重要一步。

Abstract0201264, Archuleta, U. California-Santa Barbara"COSMOS Virtual Data Center"This action supports the continued development of the COSMOS Virtual Strong-motion Data Center (COSMOS VDC), an unrestricted, Web-based, interactive strong ground motion data resource for the practicing earthquake engineering, emergency response, research, and other earthquake professional communities. The major goal of the Virtual Data Center (VDC) is to expand and significantly improve the accessibility and the use of all strong-motion records collected by the ever-growing number of US and international organizations. The VDC operates under the direction of The Consortium of Organizations for Strong-Motion Observation Systems (COSMOS, www.cosmos-eq.org), a public-interest nonprofit corporation for earthquake safety. Its mission is to expand and modernize significantly the acquisition and application of strong-motion data in order to increase public safety from earthquakes. The COSMOS structure enables the VDC to respond to both the organizations that collect the data and the users of the data (academic and professional), and ensures that the VDC evolves so that it remains responsive to the community of engineers, scientists and other users of strong-motion data.This action will advance the capability of the COSMOS VDC by further developing the proven concept of a virtual data center and its important role in coordinating the access and dissemination of strong-motion data. It will: 1) advance Web-based interfaces with the Advanced National Seismic System (ANSS) data management system; 2) advance methods for augmenting the existing VDC metadata database; 3) advance Web-based methods to facilitate efficient query and retrieval of a variety of event, station, and processed time history information; 4) develop Web-based methods for dissemination of information according to user selectable format, processing and visualization; 5) facilitate development of COSMOS standards for data formats and processing; 6) advance Web-based interfaces with other databases to enhance the metadata on earthquakes, recording site characteristics, and other relevant information for the VDC; 7) enhance Web-based interfaces and links for replication sites; and 8) advance Web-based interfaces with geotechnical databases.The VDC provides a very cost-effective way to leverage the data processing and management resources of all of the participating agencies and organizations. It continually develops, updates, and maintains a sophisticated parameter metadata environment in a state-of-the-art relational database. This approach provides a major step forward in improving accessibility of the data to the research, practicing, and emergency response communities for purposes of earthquake hazard mitigation.
