云南鲁甸MS 6.5地震灾区滑坡提取方法研究
Landslide Extraction Method of the MS 6. 5 Earthquake Stricken Area in Ludian County of Yunnan Province
摘要
Abstract
Objective] To quickly and accurately extract the landslide in earthquake stricken area by remote sensing technology. [ Method] Using the earthquake stricken area in Ludian County as the study area, we adopted the high score 1 and Landsat8 satellite OLI multi-spectral image data. [ Result] The oriented object image classification and the band operation technology were used. Combing with the pre and post earthquake images, landslide in earthquake stricken area was extracted. Based on this, we summarized the key technology and the work flow in secondary disasters of earthquake. [ Conclusion] With Landsat8 satellite images as the data source, band operation iscarried out, which can produce better extraction of seismic secondary disasters.关键词
