Acknowledgements
1. OVHcloud — Startup Program
Between February 2024 and February 2025, the OVHcloud Startup Program provided cloud credits that supported the early technical work behind SAMRoute. We thank the OVHcloud Startup Program team for their trust at a stage when the only thing we could offer back was effort. The credit window has since ended and our production hosting continues with OVHcloud on a standard commercial basis.
2. FFE — Fundación de los Ferrocarriles Españoles
The Fundación de los Ferrocarriles Españoles extended an invitation to the UITP Global Public Transport Summit in Hamburg in June 2025 — a small gesture, but the kind that lets early-stage work step into the right conversations sooner. We thank the FFE team for it.
3. Public data and standards
The reference dataset SAMRoute produces would not exist without the open and sovereign data sources we ingest, and the standards bodies whose published methodologies we build against.
3.1 Open and sovereign data sources
| Provider | Dataset / layer | Scope |
|---|---|---|
| NASA | GPW — population grids | Global |
| ESA Copernicus | GHSL — settlement grid; Worldcover — land cover | Global |
| IGN | RGE Alti — French national geographic infrastructure | France |
| Eurostat | EU statistical reference layers | EU |
| OpenStreetMap | Road graph, points of interest (thanks to its volunteer contributors) | Global |
| Mapillary | Street-level imagery | Global |
| ONISR | French road accidentology | France |
| INSEE | SIRENE — French business registry | France |
| Transport authorities | GTFS — public-transport feeds (e.g. transport.data.gouv.fr) | Europe |
3.2 Standards and reference materials
| Source | Reference work | Scope |
|---|---|---|
| CEREMA | Inspection grid for level crossings, categories 2 and 3 | France |
| EPSF | Technical referential for level-crossing safety | France |
Both standards bodies are public-sector reference works in the French infrastructure-engineering ecosystem. Their existence as published, citable, peer-reviewed methodologies is what makes a reproducible analytical layer like SAMRoute possible at all.
