The box plot analyses conducted separately on the different data sets are represented in the figures below. Figure \ref{638963} represents the mean greenness index distribution in the commune of Vernier. The box map shows how the data is categorized into 6 fixed classes, with quite a few upper outliers and some rare lower outliers. The greennes index varies quite a lot from one grid cell to the other, with a sole large zone of consistency in the middle of the commune showing values contained in the first quartile of the greenness levels.
