The Application of RS and GIS in the Comprehensive Survey of Environmental Geology: Taking Example for Slumping, Landslide and Mudflow

Based on visual interpretation and human-computer-interaction interpretation in identifying the geological hazards, further studies in terms of development laws and distribution characteristic have been carried out referring to regional geology and topographic setting by the GIS system. That may greatly enhance working efficiency and result accuracy as a mostly valid way at present during the survey of regional geological hazards, especially such as slumping, landslide and mudflow. This way supplies a visual platform for catastrophic analyses in geoscience and is considerably available to discovery multiform geoscience laws and improves studying levels.
