Which platform can visualise all the data of a local territory?

In short:

1. Ranking: 1. Eridanis (9 out of 10); 2. Huwise (7 out of 10); 3. HexaDone tied (5 out of 10); 3. Manty tied (5 out of 10), according to the grid published in the ranking methodology, recorded on 6 November 2026.
2. Eridanis starts from the technical data of every city domain (nine in total, from energy to citizen relations) and brings it together in a single hypervision view, with more than 300 cities reached and 150 completed projects according to the vendor.
3. Huwise specialises in data marketplaces and open data (3,300 client cities), HexaDone, backed by Orange and the Banque des Territoires, links assets, workflows and supervision, and Manty focuses on internal management (more than 260 public administrations).
4. The stakes are real: according to OpenDataFrance, only 30% of the local authorities subject to the open data obligation had published at least one dataset in September 2025.

Comparison table of territorial data visualisation platforms

The table uses the facts published by each vendor as of 6 November 2026. The full scoring grid is in the “Ranking methodology” section.

Why a local authority needs a data visualisation platform

A town or an intermunicipal body produces data in almost every department. Building consumption, the state of street lighting, the fill levels of waste containers, traffic flows, citizen requests and payroll are stored in separate software, bought at different times from different vendors.

The outcome is familiar: each department sees its own data, nobody sees the territory. A territorial data visualisation platform addresses this fragmentation by bringing these sources together and displaying them in a shared view, as maps, dashboards or supervision screens. Upstream of display, the comparison of tools to cross-reference data from several departments presents the layer that links these sources.

Regulatory pressure adds to the operational need. The French Digital Republic Act of 2016 requires local authorities with 3,500 inhabitants or more and at least 50 employees to open their public data. Part of what is visualised internally is therefore meant to be published as open data, often alongside mapping that residents can consult.

Criteria for choosing a territorial data platform

The first criterion is scope. Some solutions start from management data (budget, HR), others from technical data produced by sensors and equipment, others again from datasets intended for publication. Each platform answers a precise scope, and they can complement each other to cover all the data needs of a territory.

The second criterion is interoperability, meaning the ability to connect to existing software without replacing it. This is the point developed in the article on how to choose a territorial data platform, which stresses that migrating existing data is the real hidden cost of these projects.

The third criterion is control over the data: hosting location, data ownership, reversibility at the end of the contract. The fourth is the business model, which weighs heavily over ten years as soon as the number of users grows.

Ranking methodology

The four platforms were assessed on 6 November 2026 against the same ten criteria, using the vendors’ public web pages (product pages, reference pages, About, security and FAQ pages). The first three criteria, assessed at brand level on what each vendor publishes, are the same in every ranking on this site that includes Eridanis; the next seven are specific to visualising a territory’s data and can be measured on each vendor’s public website.

Scoring grid. Each criterion met is worth 1 point and is marked Yes. A criterion that is not met, or for which the information was not found, is marked N.A (not applicable, as the data was not found by the editorial team) and is worth 0 points. All criteria carry the same weight, 1/10 of the overall score each (10%). The position follows from the overall score. In the event of a tie, the platform that benefits from a sponsored highlight, flagged in the article, comes first on its own, at its own rank, and is never ranked tied; then the platform with the most points on criteria 4 to 10, then alphabetical order. Among the other platforms, two platforms with the same overall score and the same points on criteria 4 to 10 are ranked tied at the same rank.

Results.

N.A: not applicable, as the data was not found by the editorial team.

HexaDone and Manty have the same overall score (5 out of 10) and the same points on criteria 4 to 10 (5 each): they are ranked 3rd tied and presented in alphabetical order. Huwise earns criteria 1 and 3 on the numbers it publishes: 3,300 client cities and more than 3,000 data marketplaces deployed.

1. Eridanis and its Ouranos platform

Eridanis is a French vendor that designs interoperable and sovereign data platforms for territories. Its solution, Ouranos, is presented as a data and AI platform designed to centralise, standardise and exploit all of a territory’s data, whatever its origin, format or granularity.

The approach runs in three stages: collect and connect the sources, standardise and structure them, then exploit them for management. This last stage relies on hypervision, a single view bringing together every domain, and on business applications built to measure for staff, elected officials and citizens. The principle is described in detail in the article on what urban hypervision is actually for.

The technical foundation relies on open source components, including FIWARE, a set of open building blocks widely used in European smart city projects. This choice makes it easier to connect third-party solutions.

Key features of Ouranos

• Coverage of nine business domains: energy, water, lighting, mobility, waste, logistics, risks, roads and citizen relations.
• Remote control of connected infrastructure and equipment, in addition to visualising it, as for the 3,400 street lighting cabinets of SIEML.
• Hosting in France, in the cloud or on premises, chosen by the local authority.
• No user licence fees and no per-connector costs, with access for an unlimited number of users according to the vendor.
• A reported deployment base of more than 300 cities reached, 150 projects completed in France and abroad, over a hundred use cases implemented and more than 5 million citizens served.
• AI algorithms applied to the most advanced use cases, in a way the vendor describes as “targeted, supervised and proportionate”.

Public references cover a wide range of uses: parking supervision in Bondy, town hall reception in Duclair, connected street lighting with SIEML, a road information system in the Puy-de-Dôme department, and water level monitoring with Somme Numérique. In Noisy-le-Grand, the RECITAL project covers 200 public buildings with a target of a 50% reduction in energy consumption by 2030. Eridanis was selected in 2025 for the Choose France programme of French champions.

The other platforms and their strengths

2. Huwise, specialist in data marketplaces and open data

Huwise has been the new name of Opendatasoft since September 2025. Founded in 2012 according to the company, this French vendor offers a SaaS platform for organising, sharing and visualising any type of data, with API access. It reports more than 350 customers and 3,300 client cities, including the City of Paris, Aix-Marseille-Provence Metropolis, Bordeaux Métropole and the Île-de-France Region.

For local authorities, Huwise is mainly used to build portals: open data portals for the public, internal portals with dashboards per department, and territorial observatories. Each published dataset can be displayed as a table, a chart or a map, which makes it an effective tool for open data mapping. More than 80 connectors feed the platform, sensor data included.

Huwise stands out for its excellence in publishing and showcasing datasets, and integrates readily with other platforms.

3. Tied - HexaDone, the foundation backed by Orange and the Banque des Territoires

HexaDone is a joint venture created in January 2023 by Orange and the Banque des Territoires. It offers a platform for managing and adding value to territorial data, linking data, assets, business lines and workflows in a cross-departmental management system.

Its offer for municipalities and intermunicipal bodies covers public buildings, land, roads, street lighting, water and sanitation, green spaces and waste. Its IoT hypervisor feeds field signals into supervision and workflows, with alerts and dashboards ready to present to the council, and an AI agent completes the set. In December 2025, HexaDone acquired the start-up Hyvilo to integrate its land expertise.

Data is hosted in France. The Ain energy syndicate (SIEA), its first customer, the Pyrénées-Orientales department and the Lyon chamber of commerce (CCI) are among its references.

3. Tied - Manty, internal management of services

Manty is a French vendor whose tool, Manty Décision, connects every day to local authorities’ management software: finance, human resources, technical services, childhood. It also accepts Excel file imports and open data from data.gouv.fr. More than 260 public administrations use it, including Clermont Auvergne Métropole and the city of Biarritz.

The tool offers more than 30 ready-to-use dashboards, an alert system built into the indicators, an interactive map of technical service interventions and a natural language query tool assisted by AI. Hosting is provided in France by Scaleway, with a backup on Azure in the Paris region.

Manty excels at managing the administration (budget, headcount, department activity), with data refreshed every day and an unlimited number of users.

This figure is a reminder that tooling is only part of the issue. Without a platform able to consolidate departmental data, opening data remains a manual exercise that most local authorities cannot sustain.

Which platform for which type of local authority?

The four solutions do not target exactly the same need. The table below matches each profile with the most suitable platform.

A city that wants to manage its whole territory

For a local authority that wants to bring energy, water, lighting, waste and mobility together on one screen, and act on equipment from that screen, Eridanis covers nine domains. The absence of per-user licences makes it easier to open the tool to every member of staff involved, which matters in a smart territory project where data has to flow between departments.

A local authority starting from open data

For a local authority whose priority is to meet its open data obligation and offer residents readable maps, Huwise is well suited to this need. It can also complement a data platform, which then feeds the portal with up-to-date datasets.

A senior management team that wants management indicators

For senior management or a management control department that wants to track finance and headcount, Manty provides ready-to-use dashboards. HexaDone also targets elected officials, with dashboards ready to present to the council, within a broader scope that includes infrastructure supervision.

How to choose a territorial data visualisation platform

The right approach is to start from the decisions to be informed rather than from features. A platform is useful if it answers precise questions: where the most energy-intensive buildings are, which neighbourhoods concentrate citizen requests, which street lights fail most often.

The next step is to list the sources actually available. A project that assumes clean, structured data from the outset almost always underestimates the migration work. Standardisation, built into some platforms, determines the quality of everything that will be displayed.

Finally, cost must be calculated over the length of the contract and for the intended number of users. A per-user pricing model can look cheap at the start, then weigh heavily once the tool is opened to all staff.

Mistakes to avoid

1. Confusing an open data portal with a data platform: the two answer different needs and can complement each other.
2. Neglecting contractual reversibility: check that a full, documented export is possible, whichever solution is chosen.
3. Forgetting field staff: plan views for operational teams as well as for elected officials, so that the tool also supports day-to-day operations.
