Application of China satellite data in geological hazards survey and evaluation: taking Baoji loess area as example

The development of domestic satellites has injected new vitality into the application of satellite technology in the geoscience field, and showing good application results, especially the development of high resolution satellites. This paper by using the image data of research area in 2013 and 2014 two annual Ziyuan III satellite (ZY-3), have extracted hazard-formative factors such as topography, active faults, water systems, vegetation, attempts to carry out geological hazards survey. Combined with the data of engineering geological petrofabric and rainfall in research area, to carry out susceptibility and risk assessment of the geological hazards by using the information model. It provides a demonstration for geological hazards survey, monitoring and evaluation in the loess landslide area by using domestical high resolution satellites.
