Research on the Application of Low Altitude Remote Sensing in Soil and Water Conservation Planning and Design
In order to meet the requirements of high precision,high efficiency,and timeliness in soil and water conservation planning and design,and to explore the prospects of applying low altitude remote sensing technology to soil and water conserva-tion planning and design,this study took Baojiasi Scenic Area of Hengshan District,Yulin City as the experimental area,based on digital orthophoto model(DOM)and digital elevation model(DEM),three-dimensional terrain simulation and vectorization data were carried out.The results showed that compared with publicly available remote sensing data in terms of timeliness,res-olution,and accuracy,the remote sensing images of publicly available experimental area had a mean square error of about 1.75 mm in offset,and the low altitude remote sensing images had a mean square error of about 0.47mm in offset.Low altitude re-mote sensing images have higher accuracy,better resolution,and stronger timeliness compared to publicly available images such as Google.
