信息化测绘技术在“三调”中的应用分析

Application Analysis of Information Surveying and Mapping Technology in Three Surveys

为保证重要信息调查的准确性和真实性,提高国土调查质量和效率,该文以“第三次全国国土调查”为应用场景,介绍信息化测绘技术相关概念,并结合第三次全国国土调查的目的与任务,将高分辨遥感影像技术、无人机倾斜摄影测量技术、地理信息系统技术、计算机自动比对技术、全球导航卫星系统等信息化测绘技术科学地应用于第三次全国国土调查中。结果表明:将信息化测绘技术有效地应用于第三次全国国土调查中,不仅可以提高测绘技术的精确性和可用性,而且可以保证调查数据成果的可控性,完全符合实际应用需求。

In order to ensure the accuracy and authenticity of important information surveys,improve the quality and efficiency of national land surveys,this article takes the"Third National Land Survey"as the application scenario,introduces the relevant concepts of information surveying and mapping technology,and combines the purpose and task of the Third National Land Survey with high-resolution remote sensing imaging technology,unmanned aerial vehicle oblique photogrammetry technology,geographic information system technology,computer automatic comparison technology Scientific application of information surveying and mapping technologies such as global navigation satellite systems in the third national land survey.The results show that the effective application of information surveying and mapping technology in the third national land survey can not only improve the accuracy and availability of surveying and mapping technology,but also ensure the controllability of survey data results,fully meeting practical application needs.
