摘要
地理国情是重要的基本国情,是了解国情、把握国势、制定国策的重要基础,地理国情监测对象为地表自然和人文地理要素,地形与地貌是其重要的内容之一,基于LiDAR技术生产数字高程模型具有精度高、经济性强和效率高等方面的优势,本文对相关数据处理的工艺流程进行分析,对常态化地理国情监测工作提供了参考。
Geographic conditions is an important basic national condition, which is an important basis for understanding the national conditions, grasping the country and making national policy, geographical condition monitoring is one of the important contents of the earth surface natural and human geography elements. The production of DEM based on LiDAR technology has the advantages of precision, economy and efficiency. This paper analyzes the process flow of relevant data processing, hoping to provide reference for the normal geographic conditions monitoring.
