摘　　要：目前线型工程勘测设计前期阶段确定线路方案的依据为1∶5万、1∶1万比例尺的地形图,其陈旧、新建地物缺失、时势差等缺点直接影响线路走向。提出利用奥维互动地图浏览器下载Google卫星混合图,并通过自编程序批量转换坐标达到辅助勘测设计线型工程的目的。结合驮英水电站110 kV线路工程实例分析其可靠性及高效性,为线型工程前期勘测设计提供一种便捷的方法。At the preparatory stage,route survey for linear project is mostly conducted based on1:50000or1:10000topographic map,which is usually old and short of new buildings,not in conformity with the current situation.It is put forward to download the Google satellite composite map by use of Ovey interactive map browser,and write pro?gram for batch coordinate conversion as auxiliary tool of survey.Taking the110kV power transmission line project as example,the authors analyze the liability and efficiency of this application,a convenient method for survey of linear project at preparatory stage.
