环境传感数据为环境相关决策提供了重要信息。正式数据由官方环境机构提供。然而，除此之外，还有越来越多的所谓非正式传感数据，这些数据是由公民使用低成本传感器提供的。这些非正式的数据有多好，以及它们与正式的环境传感数据相比如何应用？这两种类型的传感数据是否可以有效地结合起来？本文介绍了一项在线调查的结果，调查公民科学社区，环境研究所及其网络的正式和非正式的环境传感数据的看法。研究结果表明，公众和专家对正式和非正式环境传感数据的看法不同，特别是在测量频率和数据信息提供能力方面。然而，例如，在正式环境传感数据的准确性方面也达成了一致意见。此外，双方一致认为，正式和非正式环境传感数据的整合为在几个方面，特别是空间覆盖面、数据量和测量频率方面的改进提供了潜力。有趣的是，非正式环境传感数据的准确性在很大程度上不为专家和公民所知。这表明，需要进一步调查非正式的环境传感数据和潜在的有效整合与正式的环境传感数据，如果标准化等障碍可以克服。(c)2017爱思唯尔B.V.保留所有权利。
Environmental sensing data provide crucial information for environment-related decision-making. Formal data are provided by official environmental institutes. Beyond those, however, there is a growing body of so-called informal sensing data, which are contributed by citizens using low-cost sensors. How good are these informal data, and how might they be applied, next to formal environmental sensing data? Could both types of sensing data be gainfully integrated? This paper presents the results of an online survey investigating perceptions within citizen science communities, environmental institutes and their networks of formal and informal environmental sensing data. The results show that citizens and experts had different views of formal and informal environmental sensing data, particularly on measurement frequency and the data information provision power. However, there was agreement, too, for example, on the accuracy of formal environmental sensing data. Furthermore, both agreed that the integration of formal and informal environmental sensing data offered potential for improvements on several aspects, particularly spatial coverage, data quantity and measurement frequency. Interestingly, the accuracy of informal environmental sensing data was largely unknown to both experts and citizens. This suggests the need for further investigation of informal environmental sensing data and the potential for its effective integration with formal environmental sensing data, if hurdles like standardisation can be overcome.
