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

关于公众参与地理信息系统 (PPGIS) 何时、何地以及如何影响规划决策的知识参差不齐且不完整。为了填补这一空白，我们评估了通过 PPGIS 获得的公共土地使用偏好对芬兰和波兰选定的土地使用规划案例的影响。所选案例的范围从社区到整个城市，涉及两种类型的在线 PPGIS 工具：基于地图的交互式问卷调查和基于地图的讨论平台。评估基于一个定性框架，将规划过程的潜在驱动因素组织成召集、过程和结果方面。评估结果显示参与者的数量和多样性，在规划过程开始时使用 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，计划范围和公民关注点之间的不匹配、法律框架的限制、重叠的参与和决策过程之间缺乏协调以及 PPGIS 数据的低代表性会削弱 PPGIS 对规划决策的影响。
