摘要
本文首先介绍了开放DEM数据ASTER GDEM,然后阐述了使用Global Mapper软件和ASTER GDEM数据提取输电线路断面的技术方法,并以实际工程为例,分析ASTER GDEM数据提取输电线路的精度及其在输电线路设计初期的适用性,以期为相关研究者提供借鉴。
In this paper, free Dem ASTER GDEM first was introduced, also the technical method of extraction for transmission lines section based on Global Mapper and ASTER GDEM data were studied. Finally,extract values were compared to predicted ones, and explored applicability of this technical method in transmission lines early design stage. The author hopes that this paper can provide reference for the relevant scholars.
