无人机测绘技术在年度国土变更调查中的应用探析

Application of UAV Flight Mapping Technology in Annual Land Change Survey

从时间成本、数据精度、地形限制和安全风险等方面,对年度国土变更调查工作中传统的人工调查方法与无人机测绘技术进行对比分析,结合龙岩市2023年度国土变更调查项目,介绍了无人机测绘技术在国土变更调查的应用。得出结论:无人机技术在实时动态监测、精细化数据分析、自动化与智能化测绘以及一体化多源数据融合等具有高效、科学的应用价值。

Through the detailed comparison and analysis of the specific problems in time cost,data accuracy,terrain limitation and security risk between the traditional manual survey method and UAV surveying technology in the annual land change survey work.Combined with the land change survey project of Longyan City in 2023,the application of UAV surveying and mapping technology in land change survey is introduced.The conclusion is drawn:UAV technology has high efficiency and scientific application value in real-time dynamic monitoring,fine data analysis,automation and intelligent mapping and integration of multi-source data fusion.
