Geographic knowledge map and its application in seismic knowledge representation

The paper proposes a concept of geographic knowledge map, which represents spatial-temporal knowledge, and dispalys our cognition about the geographic world. The conceptual framework of geographic knowledge map is described. It is structured diagram with semantics and syntax, and is computale. It is not only a way to visualize geographic knowledge, but also a form of graphic knowledge representation and a method of data mining and knowledge discovery. With computation, we can transfer the knowledge it represnts into foraml language description. Finally, an application of geographic knowlege map to seismic knowledge representation is studied.
