基于机载激光雷达的滩涂测绘关键技术研究

摘要

高效、高质量的测绘成果是滩涂资源开发利用的重要前提。采用传统航空摄影测量与遥感手段存在像控点布设困难、影像间不易匹配、项目周期长等问题。因此，针对激光雷达点云数据高密度、高精度的特点，根据测绘地理信息部门和海洋与渔业部门的需求，研究适应于浙江省宁波市滩涂DOM 、DEM、DSM 和DLG生产的合理方案，为工程实践提供技术支持。%It mainly introduces the various intertidal zone surveying technology based on the LiDAR . Especially for the high densities and precision ,according to the requirement of Survey and Mapping and Geo‐information Departments , and Ocean & Fishing Departments , it gives an appropriate process technical proposal for the intertidal zone DOM ,DEM ,DSM and DLG production based on small‐sized aero‐plane ,w hich is applied to the practical project .
