In this paper, we describe an online spatial decision-support system developed to support asynchronous spatial collaboration between physically distributed users, with a focus on defining spatial operators for supporting these activities in a public participation context. The developed system takes advantage of recent development on maps APIs and Web 2.0 technologies, to provide generic features that can improve spatial decision-making. It implements a web-based public participation GIS (PPGIS) while allowing geographic information based collaboration. The system, is based on a customizable platform, targets different types of spatial collaboration and user expertise, while encouraging debate between participants with similar spatial interests. The system's features, architecture and interface are presented in detail as well as usability testing procedures realized for different users' roles and expertise.
