This study proposes the general principles of hierarchical spatial reasoning. This theme belongs to the spatial information theory as it investigates hierarchical structurization of space and its use for reasoning.
Humans are able to organize and structure space in various ways to simplify spatial reasoning.
There is evidence that humans use here and in other similar cases hierarchical structures, which they impose on space to reduce the cognitive load and to improve performance. The impediment is an inadequate, insufficient, or not implementable formalization of human's representation of spatial knowledge and research in formalizing spatial hierarchical reasoning is necessary. Hierarchical spatial reasoning is any reasoning process, which applies hierarchy either to subdivide the task or space. A strategy of breaking the problem into manageable subproblems seems reasonable in the context of spatial memory. To understand how spatial hierarchies are formed and used is one of the most important questions in spatial reasoning research.
