Then, ortho-rectification was completed for disaster interpretation and analysis. QuickBird data, aerial photo, 1∶50 000 digital topographic data and DEM were taken as pre-and post-6.28 landslide remote sensing data and geographical control data respectively. Based on the analysis of formation factors of 6.28 landslide and hidden geo-hazard interpretation, suggestions are proposed for disaster prevention and mitigation.
