摘要
传统的测绘技术采集处理大范围地理信息数据时效率较低,激光雷达作为一种主动遥感技术,快速获取地物目标三维信息的功能使其应用领域越发广泛,成为继GNSS之后,测绘及地理信息领域的又一项变革性技术。LAS和E57是目前最为常用的激光雷达点云数据格式,对这2种格式具体文件结构及区别的分析具有重要意义。
The traditional surveying and mapping technology has a low efficiency in collecting and processing largescale geographic information data.As an active remote sensing technology,Lidar has the function of quickly acquiring three-dimensional information of ground objects,which makes it more widely used in the field of surveying and mapping and geographic information after GNSS.LAS and E57 are the most commonly used Lidar point cloud data formats at present.It is of great significance to analyze the specific file structure and differences between the two formats.
