This organization hosts the source code for the MobilityDB ecosystem — an open-source platform for geospatial trajectory data management and analysis.
For the conceptual overview, type system, tutorials, quickstarts, and encoding specifications, see libmeos.org — the project's public front door. This page is the repository map: where each piece of code lives.
The project is developed by the Computer & Decision Engineering Department of the Université libre de Bruxelles (ULB) under the direction of Prof. Esteban Zimányi. ULB is an OGC Associate Member and member of the OGC Moving Feature Standard Working Group (MF-SWG).
Detailed explanations and application scenarios are in the project's textbook:
Mahmoud Sakr, Alejandro Vaisman, Esteban Zimányi. Mobility Data Science: From Data to Insights. Springer, 2025.
The companion datasets and reproducible scripts live in MobilityDataScienceBook.
