IPS在格陵蘭冰川與海洋氣象地理信息門戶的設計與開發中的應用
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：
拓展這些數據集的空間與時間覆蓋范圍。其他數據集則為監測數據的分析提供支撐，包括許可區域位置、海底地形、冰川斷裂區及顯著的海底地貌特征。為規劃監測項目、管理采集的數據集并利用數據表征物理環境特征，我們設計并開發了一個基于網絡的地理門戶。該門戶輔助科學家與工程師發現并利用海洋氣象與冰情數據。在開發過程中需平衡兩個方面。
首先，科學家和工程師需要頻繁上傳、整理、搜索、可視化、分析及下載海量且多樣化的數據集。其次，由于帶寬、延遲和安全限制，網絡技術本身存在固有局限性。本文重點探討了針對這些限制所做出的設計決策及其平衡方案。
