| The Application of Remote Sensing to Investigation and Assessment of Geological Relics: A Case Study of Lianhuasi Landslides in Huaxian County, Shaanxi Province |
| The geological relics survey mainly relies on field survey, which has the disadvantages of low efficiency and high cost, and the resources are easily missed. In view of such a situation, this paper introduced high spatial remote sensing image in geological relics investigation and assessment. Firstly, the authors converted IKONOS multi-spectral image to nature color, then merged the multi-spectral image with high resolution band pan using multiplication, superposed the remote sensing data upon DEM data to form three dimensional remote sensing images and, on such a basis, interpreted landslide mass and provided the basis for the geological relic investigation and assessment of Lianhuasi landslide. The results show that it is very advantageous, practicable and economical to study geological relics with the high spatial resolution remote sensing data. Lianhuasi landslides is the rare geological relics of high speed and long distance landslides in the world, and hence it has extremely high value of scientific investigation research and popular science education for high speed and long distance landslides with international comparison significance. |
