Concepts of Spatial Similarity Relations in Multiscale Map Spaces

This chapter explores the fundamental theories of spatial similarity relations in multiscale map spaces and aims at the four subobjectives addressed in Chap. 1: (1) definitions of spatial similarity relations, (2) features of spatial similarity relations, (3) factors that affect humans’ judgments of spatial similarity relations, and (4) a classification system for spatial similarity relations in multiscale map spaces.
