A city’s data portfolio offers a wealth of untapped analytical potential. The same data can be used for a wide range of applications, and combining different data sets provides a good way to validate analytical and evaluation results through direct comparison, for example when no ‘real-world data’ is available for cross-referencing. Data such as point clouds, LoD2 or Street View data have already been used for storey detection (there is an academy here), parking space analysis and building typology. This article now explains the potential of oblique aerial images as a geodata source for assessing the potential for greening façades. It outlines how the potential index for façade greening is determined and the advantages and disadvantages of using oblique aerial images. This is followed by a brief overview of data sources used to date and their benefits for previous analyses in an urban context.
