Online GIS‐based applications that combine mapping and public participation to collect citizens' voices on their surrounding environment are a way to collect original spatial data that do not already figure in authoritative data sets. However, these applications, relying on non‐expert users, might produce spatial data of insufficient quality for the purpose for which they are collected. This article presents an approach for assessing the positional accuracy of vague landscape features, using the results from a map‐based survey completed by a group of volunteers in the Friuli Venezia Giulia region of Italy. The spatial section of the survey, gathering both georeferenced data and textual information on the mapping activity, allows the assessment of whether there is a correspondence between the mapped features and the intended map locations. The findings reveal a greater accuracy among participants in completing the mapping activity relating to degraded sites than to those of beauty.

评估感知景观数据的位置精度：来自意大利弗留利·威尼斯·朱利亚的研究

基于在线GIS的应用程序将地图绘制和公众参与相结合，以收集公民在周围环境中的声音，这是一种收集原始空间数据的方法，而原始数据在权威数据集中并未体现出来。但是，这些依赖非专家用户的应用程序可能会出于收集目的而产生质量不足的空间数据。本文使用意大利弗留利·威尼斯·朱利亚地区的一组志愿者完成的基于地图的调查结果，提出了一种评估模糊景观特征位置准确性的方法。调查的空间部分收集有关地图活动的地理参考数据和文本信息，从而可以评估所映射的要素与预期的地图位置之间是否存在对应关系。
