Digital twins and simulation/
Earth twinsEarth twins, inside Digital twins and simulation: terrain analysis, hydrological modelling, EO data cubes, essential climate, ocean and biodiversity variables and more. Every item is traced to its specification, from ASPRS Positional Accuracy Standards (elevation data) to ISO 19123-1, and runs on the open Observatory Protocol.
Plan with usArchitectureThe protocol01What it is
The reference frames, formats, services, analysis methods, machine learning and 3D models that turn observations into located, queryable and decision-ready geographic information. Every platform, sensor, processing level and ground-segment step that turns remote measurements of the Earth into calibrated, analysis-ready evidence for a site, a region or a network. AI from model to accountable operation: edge inference and model optimisation, foundation models for Earth observation and geospatial work, time-series and sensor AI, multimodal fusion and supervised agentic operations, federated and privacy-preserving learning, physical AI and robotics within stated red lines, MLOps, evaluation and model risk, and the governance frameworks that apply to each. Each technology below carries what it is, what we do with it, and the standard it is drawn against.

Short-range forecasts of weather, water, load and traffic from local and regional observations. In Earth twins, part of Digital twins and simulation, the time-series and sensor AI layer holds forecasting and nowcasting, drawn against WMO WIGOS. We build it into every site for Earth twins against that standard, and keep its version and its test results on the site’s record.

Models of the land and water drift away from reality unless they are fed by observations. Earth twins combine terrain, hydrology and atmosphere with live data from the network, so they stay current as conditions change.
