Semantic relation representation of geographic concept based on lattice

Geographic concept is spatial objects on or near the surface of the earth and they are typically complex. Semantic relation is an important problem in the description of concept. Attribute method is widely used to realize concepts' semantic representation in a great many subjects. According to the definition of geographic concept, we use ontology property to describe geographic concept instead of ordinary language description. Through analyzing the ontology property of all geographic concepts, a system of ontology property is formed to manage all ontology properties of geographic concept. Using concept lattice, the concepts' semantic relation can be expressed clearly. We give an example of few concepts in order to validate the correctness at last.
