Editorial - GeoVisualization and the Digital City

We explore notions of the Digital City through four action types relating to complimentary levels of function and argue that GeoVisualization is a key component. An interdisciplinary and international workshop on GeoVisualization and the Digital City is reported upon and the process developed for supporting and stimulating cross-disciplinary research and publication in this area described. Discussion at the workshop drew attention to key trends and themes in this area and these are reported with an emphasis on those requiring additional research or cross community collaboration. The six papers subsequently selected for development and inclusion in this special issue are summarised and drawn together in relation to these themes and action types. The importance of research efforts that address more than one functional level and support analytical map use for effective contributions to the Digital City is emphasized.
