Acquisition and Application Analysis of Low Altitude Remote Sensing Data in Soil and Water Conservation Planning

Objective] To realize the conservation planning of the high precision and high efficiency and current requirements, and to explore the application of remote sensing technology in foundation and prospects in the planning and design of soil and water conservation.Methods] The Baojia Temple scenic spot in Hengshan District of Yulin City, Shaanxi Province was chosen to carry out the low altitude remote sensing experiment. Through the establishment of digital elevation model (DEM) and digital orthophoto model (DOM), this paper analyzed comparative advantage between low altitude remote sensing data and other data, and further explored the basic application of low altitude remote sensing in soil and water conservation planning.Results] By comparison and application analysis, low altitude remote sensing not only has the advantages of good flexibility, good timeliness, high data accuracy and other basic advantages, but also can easily and quickly extract the status quo information and soil and water conservation management information such as basic information of soil and water conservation planning by using other geographic information system software. It can improve work efficiency greatly, and meet the requirements of soil and water conservation planning.Conclusion] The application of low altitude remote sensing data to soil and water conservation planning has broad prospects.
