Generalisation in the Context of Schematised Maps

In the last decade schematised maps have garnered substantial research interest from disciplines such as cartography, computational geometry and spatial cognition. More often than not, the approaches have been following their own specific goals, leaving the question of what they have in common relatively open. Most research has had metro maps and their automated creation as its focus. In this chapter we seek a more systematic treatment of what constitutes schematised maps. This chapter organises and differentiates the understanding of what schematisation is and how it relates to generalisation. Three cases studies variously explore and illustrate developments in the automatic generation of schematised maps.
