OpenStreetMap-powered mapping for mobility
SNCF Connect & Tech has added Tesmo Maps to its Tesmo portfolio a little over a year after launching the brand, pitching the mapping base as a way to turn geospatial data into clear, operational maps. Covering France and Europe, it combines basemaps, rail tracks and points of interest to make networks, journeys and scenarios easier to read. The company says Tesmo Maps is designed to improve understanding of mobility and support more sustainable uses, in line with Tesmo’s strategy.
Functionally, Tesmo Maps offers route plotting and distance calculations, with optional 3D visualisation. The maps can be customised to the use case, from passenger information through to operational needs and analytics. The solution is built on OpenStreetMap, the collaborative open mapping project, and draws on SNCF Connect & Tech’s in-house expertise in mobility data. It targets operators, local authorities, transport organising authorities and infrastructure managers, and sits in the Tesmo catalogue alongside tools for passenger information, distribution, customer relations and agent-facing applications.
“The point is that the client will remain the owner of the data,” said Julia Mason, Chief Strategy & Transformation Officer at SNCF Connect & Tech, speaking at VivaTech. “They will be able to edit their data and make their own additions. Instead of asking a supplier to add something for them, they will be able to modify their basemaps themselves, change colours and update the underlying data. For a client, that has enormous added value.”
The company’s stated aim is to make a structurally complex sector more legible. The Tesmo brand was created to offer modular, unified technology building blocks; in that vein, Tesmo Maps is presented as a common cartographic base that different business functions and interfaces can use. SNCF Connect & Tech emphasises an approach intended to make networks easier to understand and analyse, for the benefit of travellers as well as local areas.
An initial deployment is already live aboard more than 300 TGV INOUI trains. Integrated into the on-board Wi‑Fi portal, the mapping allows passengers to track their progress and surroundings while travelling. The company also flags broader potential use cases, including tourism and other consumer services, though these will depend on partners’ needs and on integration into their interfaces.
Demonstrations were staged at two sector events: the Mobco trade fair and VivaTech. In 2025, SNCF Connect & Tech reported revenue of €412 million, up 1.2% on 2024, and says it employs more than 1,300 people across Lille, Nantes and Saint‑Denis. These figures were provided by the company.
