基于Web地理可视化分析系统的研究与设计

气候研究涉及海量时空数据集,其产生和存储在分布式计算资源中。科学家们需要一个直观且方便地工具去研究分布式时空数据。地理可视化分析工具可直观且方便地访问气候资料、探索各种气候参数之间的关系及交流研究成果。本文对基于Web的地理可视化分析系统的研究与设计做一些探讨,阐述该系统具有以下功能：①互联网上海量数据集管理;②时空数据的2D/3D可视化;③气候研究中各种时空统计分析;④交互式数据分析和知识发现。此外,本文也为管理、分发、分析大数据提供参考。

The Design of Geo-visual Analytical System Based on Web

Climate studies involve petabytes of spatiotemporal datasets that are produced and archived in distributed computing resources. Scientists need an intuitive and convenient tool to explore the distributed spatiotemporal data. Geo-visual analytical tools can provide an intuitive and convenient method to access climate data, discover the relationships between various climate parameters, and share the results across different research communities. This paper reports the research and development of a web-based geovisual analytical system to support the analysis of cfimate data generated by climate model. The system is able to （1） manage large volume datasets over the Internet; （2） visualize 2D/3D spatiotemporal data; （3） broker various spatiotemporal statistical analyses for climate research; and （4） support interactive data analysis and knowledge discovery. This research also provides an example for managing, disseminating, and analyzing Big Data.
