ABSTRACT Through a literature review, this paper proposes an assessment framework to evaluate environmental open data in urban platforms under the data life cycle approach. For this purpose, a set of quantitative and qualitative indicators has been defined for each of the stages of the data life cycle: acquisition, access, analysis, and application. As confirmation of the capabilities of this approach, we illustrate the results of its application in six data portals along with analyses, comparisons, and conclusions regarding the results. The cases reveal that an interest exists in providing environmental information, but the capability to transform the data information into knowledge relevant for cities is rather low.

城市平台环境开放数据：大数据生命周期研究

摘要 通过文献综述，本文提出了一个评估框架，以数据生命周期方法对城市平台中的环境开放数据进行评估。为此，为数据生命周期的每个阶段定义了一组定量和定性指标：获取、访问、分析和应用。为了证实这种方法的能力，我们在六个数据门户中展示了它的应用结果以及有关结果的分析、比较和结论。这些案例表明，人们对提供环境信息有兴趣，但将数据信息转化为与城市相关的知识的能力相当低。
