摘要
针对埃塞俄比亚德里达瓦-达瓦利铁路项目,结合测区环境及设计要求,采用了区别于传统测绘方式的高精度机载激光雷达技术,消除了基础测绘资料匮乏、气候、交通、安全等不利因素的影响。介绍了整个应用过程、机载激光雷达技术与传统测绘技术的比较情况和地形图、横断面等测绘成果的精度、质量分析,并就项目特点作了简要阐述。
Combined with regional environment and design requirements, the high precision airborne LIDAR surveying and mapping technology which is different from traditional surveying and mapping technology is adopted in Ethiopia Dire Dawa to Dawanle Railway Project, it can eliminate the impact of the insufficient basic surveying and mapping data, climate condi- tion, traffic inconvenience, insecurity and other adverse factors. In this paper, it introduces the whole application process, comparison between airborne LIDAR surveying and mapping technology and traditional surveying and mapping technology, accuracy and quality analysis of topographic map and cross section, and makes a brief exposition of the characteristics of project.
