A brief summary of some of the relevant concepts in 3D geosciences modeling and 3D geological modeling is presented firstly. Then, the main emphasis is placed on the problem of feature-based 3D geological modeling, instead of 3D spatial data model which has been discussed so much. Although some progress has been made in this area, the major obstacle, representation and modeling of complex geological...
Remote sensing images classification is one of important approaches for recognizing interesting ground object. It is because there are several problems for normal classification methods, for example more manual intervention influence effect of classification, neighborhood information couldn't be utilized adequately, there is bad robustness to environment and so on, that particle swarm classifying...
