【摘要】：作为一门以计算机技术为核心的信息科学技术，GIS自诞生以来就成为众多学者研究的难点和热点问题，并广泛应用到社会的各个领域。目前，随着信息技术的飞速发展和GIS在各行业中应用的深入，人们对地理信息的关注、获取和使用的要求越来越高，传统二维GIS也越来越难满足市场需求。三维GIS由于表达地理现象时真实感强、可以提供更多空间信息，受到市场高度的关注并迅速发展，目前在可视化领域取得巨大的进步。尽管如此，目前的三维GIS在空间分析方面能力依然不足，尚不能称之为真正的三维GIS，而且在相当长的时间内，，三维GIS也不会完全替代二维GIS。因此，二维GIS和三维GIS的结合便是大势所趋。而如何高效的将这两者结合，实现二、三维GIS一体化，充分发挥各自的优势来服务社会将成为GIS近期发展的主流方向。 本文围绕二维GIS、三维GIS及其一体化理论展开并充分介绍了当前国内外二、三维GIS的发展与应用情况。在总结现有二、三维GIS的优势和不足之后，以笔者所在校园为例，重点探讨了结合SketchUp三维建模软件和SuperMap Objects组件式GIS开发平台如何构建二、三维GIS一体化的数字化校园系统。本文主要内容如下： 1.将常规的校园平面图数据经过配准获得准确的位置坐标，并以此为建筑物轮廓底图进行三维模型数据构建，保证后期对三维模型进行空间分析的精度。 2.对比了3款主流的三维建模软件3DMAX、SketchUp和AutoCAD，并分析了它们的优缺点。本文选择SketchUp软件对校园内场景进行三维建模，并拍摄照片作为模型的纹理。后期对模型进行优化，使系统运行更流畅。 3.利用SuperMap Objects二次开发平台，基于C#的消息机制，实现二维窗口和三维窗口的互操作响应，即二、三维联动，进而达到编辑和分析结果显示的一体化，同时实现二、三维窗口的切换，初步实现了二、三维一体化。 4.基于C#+SuperMap objects，结合Google Map API等开发完成数字化三维校园系统，初步实现了二、三维GIS一体化的校园生活平台。二、三维一体化可以很好的结合二维GIS和三维GIS的优势，很好的满足了用户对地理信息的需求。
[Abstract]:As a computer technology as the core of information science and technology, GIS has become a difficult and hot issue for many scholars since its birth, and has been widely used in various fields of society. At present, with the rapid development of information technology and the application of GIS in various industries, people pay more and more attention to geographic information, obtain and use it more and more, and traditional two-dimensional GIS is becoming more and more difficult to meet the market demand. 3D GIS can provide more spatial information because of its strong sense of reality in expressing geographical phenomena. It has been highly concerned by the market and developed rapidly. At present, it has made great progress in the field of visualization. However, the current 3D GIS is still inadequate in spatial analysis and cannot be called a true 3D GIS, nor will 3D GIS completely replace two-dimensional GIS. for quite a long time. Therefore, the combination of two-dimensional GIS and three-dimensional GIS is the trend of the times. How to combine the two efficiently, realize the integration of two and three dimensional GIS, and give full play to their advantages to serve the society will become the mainstream direction of the recent development of GIS. In this paper, the development and application of 2D GIS, 3D GIS and its integration theory are introduced. After summarizing the advantages and disadvantages of the existing two and three dimensional GIS, taking the campus of the author as an example, this paper mainly discusses how to construct the digital campus system with the combination of SketchUp 3D modeling software and SuperMap Objects component GIS development platform. The main contents of this paper are as follows: 1. The conventional campus plan data are registered to obtain the exact position coordinates, and the 3D model data are constructed for the building contour base map to ensure the accuracy of spatial analysis of the 3D model in the later stage. 2. Three popular 3D modeling software 3DMAXX SketchUp and AutoCAD, are compared and their advantages and disadvantages are analyzed. In this paper, SketchUp software is chosen to model the campus scene and take photos as the texture of the model. The model is optimized to make the system run more smoothly. 3. Using the SuperMap Objects secondary development platform, based on the message mechanism of C #, the interoperation response of two and three dimensional windows is realized, that is, two and three dimensional linkage, and then the integration of editing and analysis results display is achieved, at the same time, the integration of two, and three dimensional windows is realized. Three-dimensional window switching, the initial realization of two-dimensional integration. 4. Based on C # SuperMap objects, and Google Map API, the digitized 3D campus system is developed, and the two and three dimensional GIS integrated campus life platform is preliminarily realized. Second, 3D integration can well combine the advantages of 2D GIS and 3D GIS, and meet the needs of users for geographic information.
