LAND COVER CHANGE KNOWLEDGE REPRESENTATION USING TEMPORAL LOGIC AND OPERATION RELATIONS

Abstract. The knowledge representation model plays an important role in the dynamic extracting and web service for Land Cover Change. While former researches were mainly focus on the represent of Spatio-temporal data itself, fewer of them attended the relations of Land Cover Information associated with change. This paper focused on the Land Cover Representation Model, and presented a knowledge representation model for LCC using temporal logic and operation relations. Firstly, we analyses the new demanding of change information service for web publishing, secondly, we discuss the temporal logic of snapshots and increments; then we introduce a method to represent the operation relations between snapshots and increments; finally we construct a knowledge representation for Land Cover Change based on the temporal logic and operation relations.
