# Complementary work - interactive map of Paris trees
|
|
|
|
📘 Ce dossier est également documenté en [français 🇫🇷](./README.fr.md)
|
|
|
|
This folder is a **complement** to project P02, not part of the original submission.
|
|
The notebook `Paris_trees_analysis.ipynb`, the module `data_analysis_functions.py`
|
|
and the Folium maps `map_arrondissement.html` / `map_lieu.html` stay the
|
|
reference and are not modified.
|
|
|
|
## What it adds
|
|
|
|
The notebook produces static Folium maps. This page goes further on the
|
|
user-facing side:
|
|
|
|
- **filters** by area (districts, woods, neighbouring departments) and by
|
|
species (top 40 + "other species");
|
|
- **three views**: density by area (proportional circles), heatmap, individual points;
|
|
- **KPIs recomputed on the fly**: tree count, mean height, mean circumference,
|
|
number of remarkable trees;
|
|
- **top species / top areas** updated with the filters;
|
|
- a **single HTML file**. Leaflet and Leaflet.heat are loaded from a CDN,
|
|
with Subresource Integrity hashes.
|
|
|
|
It uses the same engine as Folium (Leaflet), driven directly in JavaScript
|
|
so the filters are practical to use.

|
## Regenerate the page
|
|
|
|
The CSV is not versioned (about 29 MB). See `../fetch-data.sh` to get it
|
|
from the City of Paris open data.
|
|
|
|
```bash
|
|
cd demo
|
|
python3 generer_carte_arbres.py ../p2-trees-fr.csv carte_arbres_paris_interactive.html
|
|
```
|
|
|
|
The script only needs the Python standard library (csv, json, random).
|
|
It samples 8,000 points for the heatmap and aggregates the 200,137 trees
|
|
by area and by species.
|
|
|
|
## Data
|
|
|
|
- Source: [Open Data City of Paris - Trees](https://opendata.paris.fr/explore/dataset/les-arbres/)
|
|
- 200,137 trees, 536 species, 184 remarkable trees.
|
|
- Missing and aberrant values are handled in the original notebook. This page
|
|
starts from the raw CSV for the display.
