EU LDT Data Modeller enables cities and technical teams to generate and manage synthetic data to support simulation and predictive modelling within the EU LDT Toolbox. It simplifies the creation of data models and synthetic data generators, allowing municipalities to represent both existing and hypothetical urban conditions.

By supporting interoperability with the Data Platform and facilitating the publication of data generators, the tool helps cities explore future scenarios, test strategies, and enhance evidence-based decision-making through reliable and reusable data assets.
