The study and assessment of ecosystem services through remote sensing has increased substantially over the last two decades, as evidenced by the publication of studies that have applied it. The technological development of satellite images has improved in terms of spatial, spectral, radiometric, and temporal resolution, allowing the space-time observation, classification and monitoring of vegetation on the surface of the Earth. However, there are remaining methodological challenges for assessing ecosystem services due to the diversity of applications, the resources used, and its study in complex environments such as cities. This systematic review is based on identifying and analysing the variety of methods concerning the application of remote sensing for the assessment of ecosystem services provided by vegetation in cities, through a classification of these methods according to the data collection source (passive sensors, passive and active sensors and the fusion of other data sources with sensors). The classification of methods has been applied to a selection of existing articles in indexed scientific databases based on a non-statistical meta-analysis that make a direct reference to the topic of interest. The results show the approaches found in every method classified, their relationships with the geographical scale and the image resolutions used, and the advantages and limitations from the data processes that comprise remote sensing. We conclude from this analysis with three key factors to consider in the selection of remote sensing methods for the assessment of ecosystem services provided by urban vegetation: the definition of the approach(es), the urban scale to be assessed, and the image resolution available.

在过去的二十年里，通过遥感对生态系统服务的研究和评估大幅增加，应用它的研究的发表就证明了这一点。卫星图像的技术发展在空间、光谱、辐射和时间分辨率方面都有所提高，可以对地球表面的植被进行时空观测、分类和监测。然而，由于应用程序的多样性、使用的资源及其在复杂环境（如城市）中的研究，评估生态系统服务的方法仍然存在挑战。本系统评价基于识别和分析有关应用遥感评估城市植被提供的生态系统服务的各种方法，通过根据数据收集源（无源传感器、无源和有源传感器以及其他数据源与传感器的融合）对这些方法进行分类。方法分类已应用于索引科学数据库中的现有文章的选择，这些文章基于直接引用感兴趣主题的非统计元分析。结果显示了在每种分类方法中发现的方法，它们与地理尺度和使用的图像分辨率的关系，以及包含遥感的数据处理的优点和局限性。我们从该分析中得出结论，在选择用于评估城市植被提供的生态系统服务的遥感方法时要考虑三个关键因素：方法的定义，
