On Saturday 6th March 2021, the eleventh Open Data Day took place with people around the world organising hundreds of events to celebrate, promote and spread the use of open data. Thanks to generous support from key funders, the Open Knowledge Foundation was able to support the running of more than 60 of these events via our mini-grants scheme.

This event received an Open Knowledge Foundation mini-grant thanks to support from the Global Facility for Disaster Reduction and Recovery Labs.

How did your event celebrate open data?

During this event, the objective was to take advantage of the virtual modality to collaborate with other locations within Mexico and provide a space to the representatives of the local authorities to give visibility to the efforts of open data, transparency and access to information in the cities of León, Mérida and Xalapa.

A panel of local experiences sought to present success stories from each city related to the use, reuse and / or publication of open data for citizen benefit, as well as the challenges that lie ahead at the local level. In addition to this, the event held a series of workshops focused on the use of environmental data, a topic that is of common interest to most citizens of León.


1) Open data, analyzing data on air quality and its pollutants
2) Open source, data collection of trees and native species in the urban environment
3) Open mapping, visualizing water management infrastructure

We used open source tools to gather, process and view data in order to co-design solutions as well as to raise awareness about environmental issues. This was possible thanks to the collaboration of:

Future Lab

Lab León / León Local Government

Laboratorio de Políticas para la Seguridad y el Desarrollo

Fabcity Yucatán

Lessons learned from your event

COVID-19 forced us to hold the event virtually, but at the same time enabled us to collaborate with other venues and share experiences.

The importance of environmental data and its availability is crucial, this allows us to make better policies and ensure that the appropriate actions are taken.

The involvement of the government in conjunction with the private sector and civil society allows greater openness to create solutions that benefit everyone.

Why do you love Open Data Day?

Because it is a collaborative space that allows us to show the benefits of open data and encourage the adoption of open data policies in government, companies and civil society to solve common problems in our communities.

Did you or your team produce any resources (datasets/tools/maps/code/etc) during your Open Data Day celebrations?

An open source web app was created that allowed participants to gather information on trees and native species of the city to be mapped collaboratively.

A repository was created on GitHub with the datasets and an interactive code notebook to visualize the data in Python.
