摘要
城市景观是轨道交通三维地理环境的重要组成部分。基于Google Earth软件批量获取城市空间坐标数据和数字正射影像图,实现城市三维地形重建。利用CityPlan建模软件快速建立多种样式建筑物模型,通过数据库实现对建筑物模型空间信息的有效管理。采用skyline软件的二次开发技术,将城市三维地形和各种建筑物三维模型统一集成,实现了用于城市轨道交通线路设计的三维城市景观的快速建立。
Urban landscape is an important part of the 3-di- mensional geographical environment for rail transit. Based on Google Earth, the urban space coordinate data and digit- al orthophoto map of the volume acquisition are obtained to renew urban dimensional topography, and through CityPlan software, both the building model and the effective man- agement of its spatial information are achieved. By using the secondary development platform of skyline API, an unified and integrated 3-dimensional terrain and urban 3-di- mensional model of buildings is realized, which helps to a- chieve the rapid establishment of 3-dimensional urban land- scape for rail transit design.
