摘要: This article reports an evaluation of the quality and scale interactions during online field experiment. A large number individuals (n= 179) worked with public participation geographic information system (PPGIS) platform a month-long experiment about regional transportation improvement decision making in central Puget Sound area Washington. The logged more than 120,000 client–server interaction events. We developed geovisual analytic technique called grapevine to evaluate using event log data. 4D space–time (GIS) visualization helps distinguish productive clusters analytic-deliberative process for guiding content analysis user-generated discussion. Comparison nature participant message exchanges before after GIS-based activities revealed significant shift focus. characterize this focus d...
