时态信息可视化模型研究及实现

时间问题是地理学中一个基本的研究问题。随着空间技术和现代信息基础设施的飞速发展,使得空间信息具备了较强的时态特性,传统静态地图中的可视化表达方式已无法满足时态信息的动态表示需求,如何在空间格局上和基于时间维的动态演化过程中,提供时态信息模拟结果的可视化分析和表达,是不可忽缺的一个环节。针对当前时空数据模型较多,而可视化研究相对较少的现状,在充分研究时态信息特点的基础上,研究了可视化动态过程所涉及的相关模型,包括概念模型、时空耦合模型以及预测模型等。

The Visual Model of Temporal Operation Information and Its Realization

The problem of time is the basic task in geography.Spatial information has stronger temporal character along with the development of spatial technology and modern information infrastructure.The way of visual expression in traditional static map can't meet the need of dynamic expression for temporal information.It is the indispensable link how to provide the visual analysis and expression for the simulating result in the space pattern and dynamic evolution process based on time dimension.In order to solve the status of the fewer researches on spatio-temporal visualization in contrast with the more researches on the spatio-temporal data models,there designed the conceptual model,space-temporal coupled model and forecasting model that the visualization of temporal operation information needed based on the research of characteristics and usage of temporal information in missile operation system.There realized the dynamic visualization in missile operate system based on the correlative visual model which selected by the change characteristics of temporal information.
