Abstract
Symbolic projection includes some characteristics that makes it suitable for various forms of spatial reasoning and in particular for qualitative spatial reasoning. Qualitative spatial reasoning techniques allow deduction of complex object relation, and can be used as a means for cognitive modeling. Spatial reasoning must be “influenced by the concept of the underlying space,” which generally relies on euclidean geometry. However, the drawback with this type of geometry is that it cannot or does not serve as a theory for reasoning. Other methods need to be considered, which cannot go beyond euclidean geometry. This chapter proposes some approaches to qualitative spatial reasoning and presents an application of symbolic projection applied to route planning. Two alternative approaches to route planning include: one involves heuristic, symbolic processing based on symbolic projection; while the other employs geometric calculations. The chapter presents the former.
