At 14:30 on June 28, 2010, continuous heavy rainfall caused enormous landslides at Gangwu of Guanling County, Guizhou Province. China Aero Geophysical Survey and Remote Sensing Center for Land and Resources immediately collected pre-landslide correlative satellite data. At the same time aerial data for the landslide whose resolution was 0.08m were obtained successfully on June 30. Using these high-resolution image data and digital elevation model, the authors adopted digital landslide technique to interpret the landslide information from the quantitative point of view on influence sphere, sliding direction, size, casualty loss and so on. At last, a series of quantitative data such as landslide area, slump scale, debris accumulation scale, damaged plantation area and buried building number, were obtained in time. The results can provide timely abundant and accurate data for front-line succor and disaster management. Based on these data, the authors hold that the Guanling landslide should be regarded as a rare large complex debris flow landslide, which had never happened before in Guizhou Province.
