Zones
Pymetropolis uses zones to import origin-destination matrices and to analyze simulation results at different spatial levels.
Pymetropolis supports up to five hierarchical zone levels, labeled level1 to level5.
Each level can correspond to a specific administrative or geographic division, enabling multi-scale
analysis.
For France, the five zone levels align with the following administrative areas:
| Zone Level | Administrative Area | Description |
|---|---|---|
| level1 | Administrative Regions | Largest geographic division (NUTS1) |
| level2 | Départements | Intermediate administrative division |
| level3 | EPCI | Public Establishments of Intercommunal Cooperation |
| level4 | INSEE Municipalities | Cities and towns, including municipal districts |
| level5 | IRIS Zones | Smallest geographic units for detailed analysis |
