APPLICATION OF MULTILEVEL REMOTE SENSING IN SURVEY OF PIPELINE ENGINEERING GEOLOGY IN LOESS PLATEAU

The Loess Plateau is the core region of the Belt and Road strategy implementation in China. In the recent years, more and more traffic, pipelines, water conservancy and other infrastructure construction are carried out in this region, and the rapid period development of long-distance pipeline construction has been come. In this paper, interpretation keys of the engineering geological conditions such as topography, geological structure and geological disasters were established by use of LANDSAT OLI/TIRS 8,GF-1 and QuickBird data in the survey of Pipeline Engineering Geology in Loess Plateau, meanwhile, use of UAV remote sensing in key section. And, the application of multilevel remote sensing in pipeline engineering geology survey was studied from four levels, low, medium, high and ultra-high resolution. The research results show that the multilevel remote sensing will play an important role in survey of engineering geology in the Belt and Road region due to advantages of rapidity, high efficiency and economy.
