ABSTRACT

Knowledge on when, where and how Public Participation Geographic Information Systems (PPGIS) influence planning decisions has been spotty and incomplete. To fill the gap, we assessed the influence of public land use preferences, obtained through PPGIS, on selected land use planning cases in Finland and Poland. The selected cases ranged in scale from a neighbourhood to an entire city and involved two types of online PPGIS tools: an interactive map-based questionnaire and a map-based discussion platform. The assessment was based on a qualitative framework organizing potential drivers of the planning process into convening, process and outcome aspects. The assessments results show high number and diversity of participants, the use of PPGIS in the beginning of the planning process, and the quality of PPGIS data representing public land use preferences may influence the content of planning documents. Conversely, a mismatch between plan scope and citizen concerns, legal framework constraints, lack of coordination between overlapping participatory and decision-making processes, and low representativeness of PPGIS data diminish the influence of PPGIS on planning decisions.

摘要

有关何时，何地以及如何影响公众参与地理信息系统（PPGIS）的规划知识的认识并不全面。为了填补这一空白，我们评估了通过PPGIS获得的公共土地利用偏好对芬兰和波兰选定的土地利用规划案例的影响。所选案例的规模从邻里到整个城市不等，涉及两种类型的在线PPGIS工具：基于地图的交互式调查表和基于地图的讨论平台。评估基于定性框架，该框架将规划过程的潜在驱动因素组织到召集，过程和结果方面。评估结果表明，参与者人数众多且种类繁多，在规划过程的开始就使用了PPGIS，代表公共土地使用偏好的PPGIS数据的质量可能会影响规划文件的内容。相反，计划范围与公民关注之间的不匹配，法律框架的约束，参与性和决策过程重叠之间缺乏协调以及PPGIS数据的代表性低，削弱了PPGIS对计划决策的影响。
