摘要
针对当前二维地理信息系统不足,本文着重介绍了三维地理信息系统的基本功能,以及如何将三维地理信息系统GIS(Geographic Information System)系统应用到线路工程的设计中;对充分利用三维地理信息系统的高清晰影像、数字高程模型和二次开发的高级功能在路径选择、提取路径断面、辅助杆塔规划条件确定、辅助基础选型、三维建模技术等方面进行了深入探讨。在未来的输电线路设计领域,三维GIS系统将发挥它的巨大作用,设计人员也将面临不断更新的设计模式。
For the insignificance of current two-dimensional geographic information system, this article focuses on basic functions of the three-dimensional geographic information system, and how to use three-dimensional Geographic Information System-GIS （Geographic Information System）to design power line projects. It takes full use of high-resolution images of GIS,digital elevation models and secondary development of the advanced features to carry in-depth discussion in the path selection,path cross-section extraction,aided determination of tower planning conditions,aided selection of foundation type,three-dimensional modeling techniques and other aspects. In the future design of power lines,three-dimensional GIS will play a huge role in it,and designers will face constantly updated design patterns.
