Implementation the sharing of hetegeneous fundamental geographic features based on concept lattice

In this paper, disparity between different basic geographical feature classification and code regulations will be handled. Each regulation is regarded as a conception model, and a common conception model for all the regulations is firstly constructed based on the conception lattice technology. And then, the mapping between the original conception model and the common conception model will be mined and represented as an association. In this way, the mapping relations between the conceptions in different regulations will be derived. This kinds of mapping relations can be used as the knowledge to support the consistent access to the different geographic data based on different regulations. Thus, based on the concept lattice theory, the sharing of heterogeneous fundamental geographic information data can be primary achieved.
