IPS在格陵兰冰川与海洋气象地理信息门户的设计与开发中的应用
Abstract
Completed and planned metocean and ice measurement programs off Greenland's eastern and western coasts result in large and varied datasets characterizing physical phenomena such as icebergs, sea ice, seabed scours, weather, surface waves, ocean currents, and water properties. Future planned measurement programs will expand on the spatial and temporal breadth of these datasets. Other datasets support the analysis of the measurement data including license area locations, bathymetry, glacier calving areas, and notable submarine features. In order to plan measurement programs, manage the acquired datasets, and use the data for characterization of the physical environment, a web-based geoportal was designed and developed. The geoportal aids scientists and engineers in their discovery and use of metocean and ice data. The geoportal development required balancing two aspects.
Firstly, scientists and engineers have extensive needs to upload, organize, search, visualize, analyze, and download large and varied datasets. Secondly, there are inherent limitations of web technologies due to bandwidth, latency, and security constraints. Many design decisions were focused on balancing these issues and are presented here.
摘要：
拓展这些数据集的空间与时间覆盖范围。其他数据集则为监测数据的分析提供支撑，包括许可区域位置、海底地形、冰川断裂区及显著的海底地貌特征。为规划监测项目、管理采集的数据集并利用数据表征物理环境特征，我们设计并开发了一个基于网络的地理门户。该门户辅助科学家与工程师发现并利用海洋气象与冰情数据。在开发过程中需平衡两个方面。
首先，科学家和工程师需要频繁上传、整理、搜索、可视化、分析及下载海量且多样化的数据集。其次，由于带宽、延迟和安全限制，网络技术本身存在固有局限性。本文重点探讨了针对这些限制所做出的设计决策及其平衡方案。
