Study of semantics in the context of Geographic Information Systems (GISs) usually focuses on association of meaning with spatial data that constitute the input to these systems. The goal is to create new data models that enable richer interaction with GISs. In this paper we widen the perspective of such studies and explore the implications of associating semantics withmap styles that are present implicitly in the output of GISs. Traditionally in computer science style of rendering/presenting data has been viewed as extraneous information that does not add semantic value to data. In GIS however, several styles of rendering maps are possible, and these styles are often motivated by functionality. Thus a map style has a strong association with meaning. In this paper we explore the methods of associating semantics with the style of a map. We discuss the various levels at which semantic associations with map styles can be established, and how this lead to creation of new map rendering styles that exhibit coherence in visualization of spatial information.
