Abstract
It is the essential factor in citizen participation in the planning of urban renewals that there are good mutual communications between local residents and planners. Citizen participation in the three-dimensional urban data generating process provides manyfunctions to attain full communication among the persons concerned with the planning. This paper discusses the fundamental concepts of citizen participation in the 3-D urban data generating process, and proposes the data generator for non-specialists. An actual case study in the renewal area in the city of Sanda in Hyogo Prefecture is presented to explain the techniques and the characteristics of the data generator. It is emphasized that actual operations have been done by the residents. Cityscape simulations also have been carried out using the data generated by the operations. And besides measurement of the communication effects by the simulations has been tried in the actual explaining meeting.
