| 摘 要： | 随着GIS数据不断更新,大量的GIS历史数据也不断累积起来。本文即是着眼于如何有效利用累积下来的多个时期的数据,模拟地信时空过程,让人们能直观了解空间信息的发展变化过程。论文先介绍了由地理信息时空数据建立的三维时空数据库,然后阐述了在此数据库支持下的地信时空过程可视化的实现技术。本文的研究是一次时态GIS与3D-GIS结合应用的尝试,实现了4D概念下更为逼真和动感的地理信息服务方式。

| Abstract: | As the continuous updating of GIS data,large amount of GIS historical data has been accumulated.This paper is focused on how to effectively use the accumulated data of multiple periods,to inverse the Geo-information space-time process,so that people can intuitively understand the process of development and changes of spatial information.This paper first introduced the 3D space-time database found on the Geo-information space-time data,then described the technology of visualization for Geo-information space-... |
