Collaborative, Secure, and Replicable Open Source Data Lakes for Smart Cities

ODALA is a strategic European project that was launched in September of 2020. It is a collaboration between European cities, different private companies and research institutes and the goal is to improve data management and sharing between cities and regions. Basically, ODALA is an initiative that aims to facilitate decision making in public administrations.

Improving the environmental footprint and the quality of life in cities.

What is ODALA about?

Launched in September 2020, the “Collaborative, Secure, and Replicable Open Source Data Lakes for Smart Cities” (ODALA) is a strategic project to improve data management in cities. European cities and regions from four different countries together with a cluster of private companies and research institutes will leverage open source technologies and digital transformation – for the benefit of public administrations.

ODALA is an initiative that aims to promote the use of Big Data to facilitate and speed up decision-making in public administrations. 

One of the goals of the ODALA project is to set up a data lake - an environment that will help cities connect all kinds of data sources cross departments and cities.

This initiative has a social focus and is designed to help the use of Smart Cities technology simply and practically. In this way, ODALA seeks to facilitate the implementation of data-based tools in European public administrations.

This initiative is contextualized within the framework of Smart Cities, a sector in a continuous process of innovation and growth, which is focusing on the use of data as a source of knowledge for citizens, which allows them to improve their quality of life and anticipate future challenges.

The ODALA project is co-financed by the European Commission with a budget of 2,3 million euros until August 1, 2023.


"A virtual place to bring data together in a secure and trusted way and to make it usable for the city but also for third parties is essential. ”

Cities are implementing, testing and validating the tools developed in the project. 


Use Cases


Mobility is major cause of carbon emission, thus a key domain to fight climate change. In fact, it contributes to 29% of total economy-wide greenhouse gas emissions in the US and EU (Japan: 17%). Nevertheless, individuals and cities are, frequently, not aware of their own mobility CO2 footprints. This issue needs to be addressed urgently as data shows that since 1990, transport emissions in the EU have grown by 33%.

ODALA uses a mobility data toolkit, data-centric based, ML supported solutions that compute fine-grained CO2 footprints. The goal is to use crowd-sourced data to improve awareness and behavioral changes in people and organizations. The analysis of these footprints can provide incentives to change individual behavior and inform city-wide demand and supply changes (e.g., new bus routes, infrastructure changes).


Activity 5 of the CEF ODALA project has the overall ambition to elaborate on those components currently needed within the domain of Smart Cities to work with and share data that relates to environmental use case scenarios. The ambition of this activity is not to design an end-to-end framework to do so, but rather focus on those domain specific components (specifications and tools) that are needed on top of and compliant with the overall ODALA architecture, as defined within ODALA Activity 2.



“We are very pleased to have a consortium of strong partners with technical expertise and a large network of key stakeholders. Together we form the foundation for outstanding project success.”
