将科学可视化技术应用于地理信息系统之中,增强地理信息系统对时空多维数据的显示、处理功能,是当前的研究热点之一。通过对现有地理数据组织、显示简要概述的基础上,提出一种基于体素的时空多维数据组织方式。并通过二维、三维显示及动画形式的研究,从技术上对科学可视化与地理信息系统的结合进行初步的探索。最后,通过对时空多维数据可视化算法的研究与实现,为在地理信息系统中进一步将可视化技术走向实用提供基础。

It is a hotspot for applying Visualization in Scientif ic Computing (VISC) to Geographic Information System (GIS). VISC is an effective and efficient method for promoting the capability of processing and visualizing the spatio temporal geo referenced data. In this paper, firstly, after review ing the current data structure and visualization, we focus on volume graphics an d provide a based voxel spatio temporal multi dimension geo referenced datab ase. Secondly, by studying two dimensional rendering, three dimensional renderin g and animation, we initially explore the method of integrating GIS and VISC. Fi nally, the results of the finished database and some methods of spatio temporal visualization will be regarded as the base of the further application of VISC in GIS.
