摘要
时态GIS是GIS向多维化发展的产物。介绍了时态GIS的概念、特征、关键技术及主要时空数据模型。针对艾滋病传播的时空变化特性,提出了基于时态GIS的艾滋病时空分布动态监测的初步解决方案,较详细探讨了基于基态修正模型的艾滋病时空分布动态监测历史库与现时库动态更新方法。
Temporal GIS is the outcome of the multidimensional development of geographic information system. This paper gives a brief presentation about the concept, characteristic, main technique and spatial-temporal model of Temporal GIS. A primary solution based on spatial-temporal GIS has been proposed as to the dynamic inspection to the spatiotemporal distribution of aids, considering the fact that the diffusion of aids will change with the change of space and time. At the same time, a detailed discussion about how to update history database and nowadays database dynamically has been made. The discussion is based on the modification of ground state model.
