International Workshop on Bathymetry and Coastal Topography Data Management

9803834这一行动是为了支持1998年3月在西雅图举行的为期两天的研讨会，讨论水深和沿海地形数据的全球共享、整合、标准化和管理。与其他与海洋相关的主题不同，海啸(地震海浪)分析需要整个海洋盆地的综合数据，以及干燥的沿海信息；例如，从10,000米深的海沟到海拔50米的海沟。准确和高分辨率的数据不仅对数值模拟很重要，而且对其他类型的海啸研究也很重要。讨论的主题将是：现状和数据审查、数据系统的长期和最终目标、近期目标、标准化高程和深度基准以及数据点的坐标，并与其他研究小组协调。这些议题将在研讨会之前按区域进行讨论。预计这次讲习班将改进水深测量数据，从而在减少海啸灾害方面取得重大进展。***

9803834 Yeh This action is to support a two-day workshop in Seattle, March 1998, to discuss global sharing, integration, standardization, and management of bathymetry and coastal-topography data. Unlike other ocean-related topics, tsunami (seismic sea wave) analyses require the integrated data for the entire ocean basin, plus dry coastal information; for example, from 10,000 meter deep ocean trenches to 50 meters above sea level. Accurate and high-resolution data are important not only for numerical simulations, but also for other types of tsunami research. Discussion topics will be: present status and the data review, long-term and ultimate goals for the data system, near-future goals, standardize the datum of elevation and depth, and the coordinates of data points, and coordinate with other research groups. The topics will be discussed regionally prior to the workshop. It is expected that this workshop will lead to improvements in bathymetry data, thereby leading to significant advancement in tsunami hazard mitigation. ***
