Structural hierarchy of spatial knowledge based on landmarks and its application in locality descriptions

Locality description is the most common spatial activity in everyday life, and is decided by the spatial cognition. In spatial cognition, spatial knowledge is often structured hierarchically and results in the hierarchical locality descriptions. In this paper, we propose the structural hierarchy of spatial knowledge based on landmarks and topological spatial relationship of disjoint, and present two types of structural hierarchy based on landmarks from the point view of spatial cognition. Cognitive and computational aspects are provided to generate hierarchical locality descriptions. Finally, we use three cases to demonstrate the proposed methods.
