Use of digital visualization tools in planning is nowadays widely practiced around the world by various contributors to the field and in different planning scales. Visualization facilitates perception of underlying thoughts and objectives of planning alternatives and consequently assists with communication of the plan to stakeholders of different groups. This – in turn - enables them to actively and efficiently participate in the procedure from the very initial stages to the implementation phase thanks to the insight provided by user-friendly visualization tools. Available visualization tools for planning, however, are either not integrated and efficient enough or too resource- or expertise-demanding and thus not entirely fulfilling the qualities mentioned above. This study is a search for a conceptual framework for the optimal web-based visualization tool. Web-basedness diminishes temporal and spatial distance among the users and planning agents and provides the possibility for more participation in and interaction with planning projects. Within this study, major characteristics of an optimal tool have been investigated through literature and online resources, contacts with experts and practitioners, a survey over existing products and visual analysis of the outcomes. An evaluation cube was initially developed and then used as the basis for a set of duality criteria. A selection of visualization tools were examined against those criteria and results were demonstrated visually. Eventually, findings were used to provide a backcasted example of the optimal tool and suggestions were made for actual development of the package to be used by planning agents.
