摘要
本文全面探讨了数字地形图测绘技术的发展历程、当前应用及未来发展方向。从20世纪60年代初步应用计算机技术到地形图制作的萌芽阶段,再到21世纪高分辨率卫星遥感、无人机航拍和激光雷达技术的广泛应用,数字地形测绘技术实现了质的飞跃。本文详细分析了激光雷达测量、无人机测绘和三维建模技术在地形测绘中的应用及其优势。在此基础上,探讨了数字地形图测绘技术面临的挑战,如数据处理的自动化、多源数据的集成应用及高分辨率测绘的需求,并提出了未来发展的方向,包括技术集成化、处理自动化和精细化测绘的趋势,以期为相关人员提供参考。
This article comprehensively explores the development history,current applications,and future development directions of digital topographic mapping technology.From the early application of computer technology in the 1960s to the embryonic stage of terrain map production,and then to the widespread application of high-resolution satellite remote sensing,drone aerial photography,and LiDAR technology in the 21st century,digital terrain surveying and mapping technology has achieved a qualitative leap.This article provides a detailed analysis of the applications and advantages of LiDAR measurement,drone surveying,and 3D modeling technology in terrain surveying.On this basis,the challenges faced by digital terrain map surveying and mapping technology were discussed,such as the automation of data processing,the integration and application of multi-source data,and the demand for high-resolution surveying and mapping.The future development direction was proposed,including the trend of technology integration,processing automation,and fine surveying and mapping,in order to provide reference for relevant personnel.
