摘要
传统的土地利用动态调查方法既费时又费力,难以应对当下城市发展过程中遇到的各种土地规划与利用方面的问题。随着低空摄影测量技术的不断进步,以无人机为平台的遥感数据采集和处理系统正逐渐受到遥感与测绘行业的青睐。该文以无人机倾斜摄影测量技术为数据获取手段,研究利用数字表面模型(Digital Surface Model,DSM)数据获取城市土地利用变化信息,并进一步应用到城市土地利用动态监测工作中的方法,为解决城市建设过程中面临的土地资源利用监测方面的问题提供了较好的解决方案。
The traditional dynamic survey method of land use is time-consuming and laborious,and it is difficult to deal with various land planning and utilization problems encountered in the current urban development process.With the continuous progress of low-altitude photogrammetry technology,the remote sensing data acquisition and processing system based on UAVs is gradually favored by the remote sensing and mapping industry.This paper takes UAV's tilt photogrammetry technology as a means of data acquisition,studies the use of DSM(Digital Surface Model)data to obtain the information of urban land use change,and further applies it to the dynamic monitoring of urban land use,which provides a better solution for solving the problems of land recourse use monitoring encountered in the process of urban construction.
