Abstract The development of domestic satellites, especially high resolution satellites, has injected new vitality into the application of satellite remote sensing to geological survey, and has shown good application results. By using the image data of 2013 and 2014 obtained from the ZY-3 satellite (ZY-3), the authors extracted hazard formative factors such as topography, active faults, water systems, vegetation and artificial engineering from, with the purpose of carrying out geological hazards survey in Baoji loess area. Combined with the data of engineering geological petrofabric and rainfall in Baoji area, the authors carried out susceptibility and risk assessment of the geological hazards by using the information model. The results provide a demonstration for geological hazards survey, monitoring and evaluation in the loess landslide area by using domestic high resolution satellites.
