摘要
全国土地调查是一项重大的国情国力调查,是查实查清土地资源的重要手段[1]。本文研究了无人机测绘在第三次土地调查中的应用,并通过以下3个方面进行研究:1)研究项目区状况; 2)无人机的航空摄影与第三次全国土地调查的要求对接; 3)不同无人机优势结合,通过无人机航摄测量技术快速得到该区域的符合调查底图精度要求的正射影像图和数字高程模型。本文以甘肃省第三次土地调查试点古浪县测绘为例,无人机测绘在第三次土地调查中具有十分明显的优势。
The national land survey is a major national and national strength survey,is an important means to verify and identify land resources.The application of UAV mapping in the third land survey is studied in this paper.And through the research on the following three aspects:1)research project area;2)for the third national land survey and docking of UAV aerial photography;3)different UAV advantages,through the key technology of UAV can meet the requirements of rapid orthophoto survey map accuracy map and digital elevation model the area measurement technology.This paper takes Gansu Province third land survey pilot Gulang County surveying and mapping as an example,UAV mapping in the third land survey has a very obvious advantage.
