ABSTRACT
The term “space” is difficult to define (see “What is space?” inset, page 84). We all have an intuitive idea about the concrete space in which our bodies move. In the context of GIS, we normally use the term “space” to refer to “geographic space”: the structure and properties of the relationships between locations at the Earth’s surface. In this chapter we examine space more carefully by considering the different ways of representing and reasoning about geographic space.
