地质公园三维电子地图的设计与实现

结合三维建模和电子地图的基本理论,根据地质公园的特点,利用ERDAS实现大面积区域三维可视化,并结合3DS MAX丰富的建模技术及强大的动画制作功能,在地质景观演化方面做了初步探讨。采用“超地图”的形式来组织各种地图数据以及超媒体相关信息,从内容结构设计及特点进行论述,实现了伊通火山群的三维电子地图,展示出“伊通型火山”的特点。为科研、科普和旅游提供了方便、直观的信息表现形式,拓宽了电子地图的应用领域,同时也丰富了电子地图的研究内容。

THE DESIGN AND REALIZATION OF THE 3D ELECTRONIC ATLAS IN THE GEOPARK

The rapid development of the information technology is providing more and more conveniences for acquiring,processing,and analyzing and expressing of spatial information.As one kind of visual expressing products of spatial information,the electronic atlas is applied in the public and many other fields in various forms.In this paper,combining with the fundamental theories of 3D modeling and the electronic atlas and according to the features of geopark,we realize the 3D visualization of large area by modeling software ERDAS,by 3DS MAX and its strong animated pictures function,and from here we initially discuss the evolving of the geological sight we choose the "hyper-map" to organize various information of maps and hyper-media.And we realize the electronic atlas of the volcano group in Yitong,Jilin,China.The atlas provides direct and convenient expression patterns of information for scientific research,popularization of science,and tour.Moreover,it extends the application of the electronic map,and also enriches the research content of the electronic map.
