中文摘要: 时空数据模型是多维动态空间信息可视化中需要重点研究的内容。然而,目前已经提出的时空数据模型大都只关注于时间、空间之间的关系,缺乏对空间对象连续变化的表达能力,忽视了运动目标另外一个基本特征- - 属性,而运动目标属性间的语义关系往往是用户最关注的内容,因此本项目将综合考虑空间要素、时间要素和属性要素,探讨既能表达空间对象的连续变化又能表达空间对象的离散变化的时空数据模型-运动目标时空对象模型(MODM),在此基础上,研究运动目标间语义关系的时空表达模型。本项目主要包括以下三个研究内容:基于快照和函数的面向对象运动目标时空数据模型、运动目标间语义关系的时空建模、运动目标及运动目标间语义关系的可视化技术研究。本项目的研究意义在于从基本理论和方法上解决空间运动目标的表达与表现问题,解决空间运动目标间语义关系的时空建模与可视化问题,为地理信息系统拓展新的应用领域。

英文摘要: Spatio-temporal data model is multidimensional dynamic spatial information visualization in the content which should be researched. Spatial-temporal data model has been proposed, however, are mostly focused on the relationship between time and space, the lack of a continuous changes of spatial object expression ability, ignored another basic characteristic of moving targets, attributes, and the semantic relations between motion target attribute is usually the most attention to the content of the user, so this project will be considering spatial factor, time elements and attributes, and both can express spatial object continuous change can express a discrete changes of the spatio-temporal data model of moving object model of time and space (MODM), and on this basis, study the target motion model of semantic relation between time and space expression. This project mainly includes the following three research content: snapshots based on moving object and function of object-oriented spatio-temporal data model and moving object semantic relationships between spatio-temporal modeling, semantic relations between moving targets and moving targets, the visualization technology of research. Objective to study the significance of this project is from the basic theory and method in solving the problem of space expression and performance of moving targets, solve the semantic relationship between space moving object modeling and visualization of space and time, for the geographic information system to expand new areas of application.
