Ongoing discussion has a focal role in urban planning and development process where actors from professional planners, decision makers to lay persons share their opinions, aims and needs. The conflicting nature of urban planning is often negatively highlighted though the collision of opinions should be valued. Instead of the attempt to achieve a consensus between different stakeholders in planning process the divergent and multiple perspectives should be more openly and legitimately examined. To enable agonistic planning process and outcome, the question concerning the scale of the participants and the quality of the information should be re-examined. This paper discloses the possibility of the Internet-based softGIS service to generate place-based information of the residents’ experiences and use of their living environment. In addition to the data gathering from the residents’, softGIS aims to deliver this information in multiple ways and in different phases to urban planning process. In this paper we argue that softGIS can support and complement the planning process by feeding it with the experiential information otherwise too complicated to grasp and too laborious to handle.  SoftGIS can therefore function as a trading zone that offers common space for different actors to trade their thoughts of the living environment.
