Maps are still predominantly understood as silent. This thesis argues that sound can play a more significant role within a reconceptualized study of cartography,introduced here using the term 'audiovisual cartography,' in which visual and acoustic design complement each other and together provide alternative possibilities for assisting in the examination and communication of complex spatial information concerning a wide variety of subject matters. This thesis examines theoretical,design,technological,and user acceptance and comprehension challenges for audiovisual cartography,in particular,interactive audiovisual maps designed for use and distribution over digital networks. Drawing on previous research literatures concerning sound design for films and games,and research concerning predominantly silent interactive and animated maps,a theoretical framework for audio-visual cartography and tentative guidance for a variety of ways in which sound may be used to create,add,or reinforce meaning as part of maps are proposed. A model for implementing interactive audio-visual map applications is outlined and a portable,cross-platform software implementation meeting the requirements of this model is introduced. The results of user evaluations with a set of interactive audiovisual map prototypes are discussed. Finally,an example application,Canada-LISA Commodity Trade 1976-2000,demonstrating a set of design ideas and highlighting issues concerning the development,distribution,and use of interactive and animated audiovisual maps is discussed. This research contributes new ideas for the design of interactive maps and visualization tools for spatial data,and provides an open-source sound subsystem implementation upon which additional research could be based.
