Design of Data Visualization Component for Ocean Environment Monitoring

摘要:

海洋环境监测对我国海洋经济的发展具有重要促进作用;针对当前海洋监测独有的数据可视化需求及软件复用度不高问题,提出一种基于ActiveX技术的数据可视化控件,在建立坐标映射模型基础上实现对多区域、异构海洋环境数据的标量场及矢量场展示,并提供鼠标漫游、图像放大、图像移动等丰富的界面交互手段;在实际应用中通过配置控件接口及属性便可将其复用在各类海洋监测系统中;实践表明该控件的引入满足了海洋环境监测需求,有效降低了海洋监测软件系统中数据可视化开发的复杂性。

Abstract:

Ocean environment monitoring plays an important role in developing the ocean economy in China. According to the unique ocean visualization requirements and low reusability problem, this paper designs a visualization component based on the ActiveX technology. Through constructing the coordinate mapping model, the proposed component implements the visualization of the heterogeneous monitoring data using scalar and vector fields, and provides the rich interactive methods like roaming, zooming and moving. Combining with the real requirements, it can be used in multiple ocean monitoring systems by setting the component interfaces. The results prove that the component reduces the software development difficulties and meets the visualization requirements efficiently. 
