| 摘 要： | 研究目的:利用2DGIS中城镇地籍数据信息快速建立城市三维模型。研究方法:首先对城镇大比例数据进行归类,提取适合三维建模的点、线、面要素,然后对要素进行重新组织,利用ArcScene,依据三维表达的要求,对地形背景建立DEM并与DOM叠加处理,界址点、控制点等点状地物建立三维独立地物符号库,一般建筑物按高度进行拉伸,而对标志性建筑物采用三维建模软件按二维轮廓进行精细模型制作。研究结果:成功地对某市大比例尺城镇地籍数据进行三维可视城市三维模型构建。研究结论:利用2DGIS中城镇地籍数据信息建立城市三维模型方法可行有效,有利于推进三维地籍的发展。

| Abstract: | The purpose of this paper is to rapidly create 3D city model by using the cadastral data of towns and cities in 2D GIS.Research methods are designed as following:(1) classify the large-scale data of towns and cities;(2) select the factors of point,line and surface which are suitable for 3D modeling;and(3) according to the requirements of 3D expression,reorganize the factors in order to establish the DEM of the landform and then stack it with the DOM by using the Arc Scene software;(3) establish the 3D indep... |
