The research area is located in the tropical rainforest region in Southwest China, with a humid and rainy climate, and there are many soils and vegetation in this area and few exposed rocks. These factors have brought great difficulties to remote sensing mapping. In order to minimize the impact of disturbances caused by tropical rainforest coverage areas, the authors used high spatial resolution remote sensing data, Radar remote sensing data, and elevation data. On the basis of conventional remote sensing geological interpretation methods, the authors used the correlation between vegetation and underlying bedrock, soil and underlying bedrock, topography and geological bodies, human engineering activities and lithology to summarize the interpreting marks of various geological bodies in this region such as hue, morphology, geomorphology, and human engineering activities and develop remote sensing geological interpretation and geological mapping of tropical rainforest coverage areas, thus achieving good results and providing relatively reliable remote sensing geological interpretation methods for similar regional geological surveys.
