A by-product of working with the [OpenData repository of the city of Paris](https://opendata.paris.fr/explore/?sort=modified): here **public lights** (bottom layer, orange-ish) and **trees** (top layer, multicolor). Both datasets have an information on the objects height, which were superimposed to a Digital Elevation Model of Paris, interpolated in python from [**SRTM** data](https://www2.jpl.nasa.gov/srtm/) (Z-scale overly exagerated). The lights were colored according to their light temperature (available in the dataset), while the 25 most common kinds of trees were colored by species. The resulting point cloud gives pretty interesting patterns (some of which I've annotated), especially in cemeteries and on the biggest streets. Too bad most of the public parks don't have associated tree data... And if you don't know it already, I'd definitely advise French speakers to listen at this nicely related song by Maxime Le Forestier: [Comme un arbre](https://www.youtube.com/watch?v=clDxk0Wh--4).
