European Earth observation, engineered for the industries that need to act on what they see.
Léargas is a managed DataOps platform for Earth observation data. It aligns to ESA infrastructure and Copernicus standards, integrates IBM's geospatial foundation models, and packages all of it into something reinsurers, infrastructure operators, and regulated industries can actually deploy.
Earth observation data has never been more abundant. Or harder to use.
Copernicus delivers petabytes of imagery every month. Commercial constellations add petabytes more. Foundation models trained on satellite data are now released openly. The raw material for high-quality decisions about climate risk, infrastructure integrity, and regulatory compliance is genuinely available.
The bottleneck has moved. It is no longer access to data or models. It is the engineering work between the satellite and the decision: ingest, reproject, validate, fuse, analyse, deliver, and govern. That work is bespoke for every use case and every organisation, and it is exactly where most Earth observation programmes stall.
Built inside the European space ecosystem. Aligned to its standards.
Léargas began with a question about scale. The European space programme has produced one of the largest and most consistent Earth observation archives in the world. The data is free, open, and well-governed. The foundation models trained on it are increasingly capable. What it lacked was a delivery layer that European industry could trust to operate inside its regulatory environment.
We started building that layer on top of the European Space Agency's Network of Resources and the Microsoft Planetary Computer. We integrated IBM's geospatial Granite models for analysis and tested them against ESA's own benchmarks. We engineered DataOps patterns specifically for Copernicus Sentinel data, including the reprojection, fusion, and quality-control steps that catch most teams out.
Built on ESA Network of Resources and Microsoft Planetary Computer
Integrated IBM Granite geospatial foundation models
Engineered DataOps patterns for Copernicus Sentinel-1, 2, and 3
Aligned to STAC, OGC, and ESA Earth Observation standards
Validated against EU AI Act and data residency requirements
A DataOps platform that takes you from raw satellite data to actionable answer.
Léargas handles the engineering layer most organisations cannot build in-house. Ingest from Copernicus and commercial sources. Reproject and fuse across spectral bands. Apply foundation models for analysis. Deliver outputs in the format your business systems already use.
Multi-source ingest
Copernicus Sentinel-1, 2, and 3. Commercial EO providers. SAR, optical, and thermal data unified through a single pipeline.
Reprojection and fusion
Cross-sensor harmonisation, cloud masking, atmospheric correction. The work that pre-trained models cannot do for you.
Foundation model analysis
IBM Granite geospatial models for land cover, change detection, anomaly identification. Fine-tunable for client-specific use cases.
Industry-ready outputs
GIS exports, API endpoints, scheduled reports, and direct integrations with risk and asset management platforms.
Governance and lineage
Every output traceable back to its source data, processing chain, and model version. Built for regulated industries.
Managed or self-deployed
Run as a managed service on Léargas infrastructure, or deployed into your tenant under your governance regime.
Architected in the European cloud. Aligned to European standards.
Léargas runs on infrastructure that European industry already trusts, integrates with the standards European regulators already require, and operates with the data residency profile most procurement teams will need to see.
