摘　　要：新建湘西某变电站工程工期紧、任务重。站址植被茂盛,交通不便,不利于传统测量手段进行数据采集。利用机载LiDAR技术对该站址进行初步测量。针对该技术在坡度较大地区精度较低的特点,采用普通航测手段进行修测。最终在较短时间内得到满足设计要求的DEM数据。Construction of the new substation had a tight schedule and heavy task in Xiangxi.Lush vegetation and the inconvenient transportation were not conducive to the traditional measurement methods for data collection in the station site.Airborne LiDAR was used to carry out the preliminary survey in the site.In view of the low accuracy of this technology in areas with the large slope,the ordinary aerial survey methods were used to carry out the correction measurement.Finally,DEM data meeting the design requirements was obtained in a short time.
