摘要:
随着数字城市的发展,传统的二维 GIS 已经无法满足当前的需要,三维 GIS 在可视化、漫游、真实度等方面具有明的优势,正逐步替代二维 GIS。 三维 GIS 的核心就是三维空间数据库的设计,在三维空间数据库设计中面临三维空间的复杂性,三维模型建设周期长,二、三维数据联动性差以及浏览效果差等问题。 分析了三维空间数据库特点,对比了多种三维建模方法,深入研究二维三维数据联动技术,采用 SketchUP 批量处理二维 GIS 数据,实现快速三维场景建模,利用ArcGIS 平台驱动三维模型实现二维三维数据联动。 该方法设计的三维空间数据库保证了二、三维数据的无缝连接,实现了三维空间查找和全景浏览。 为三维空间数据库的建设提供了一种简单、高效、真实度高的技术方法。
Abstract:
With the development of digital city,the traditional 2D GIS has been unable to meet the current needs,and the 3D GIS has obvious advantages in visualization,roaming,authenticity and so on,which is gradually replacing 2D GIS. The core of 3D GIS is the 3D spatial database design which faces with these problems of the complexity in three-dimensional space,the long cycle of the three-dimensional model construction,the poor linkage between two and three dimensional data and the effect of poor browsing. For this,we analyze the characteristics of the three-dimensional spatial database,compare several kinds of modeling methods,and deeply study the 2D and 3D data linkage technology. The SketchUP batch processing is used for 2D GIS data in order to realize the three-dimensional scene modeling,and the 3D model is driven by ArcGIS platform to realize 2D and 3D data linkage. The three-dimensional space database designed by this method ensures the seamless connection between the two and three dimensional data,and realizes the 3D spatial searching and pano ramic browsing. It provides a simple and efficient technology with high fidelity for the construction of 3D spatial database.
