YouthMappers are celebrating Open Data Day!

The eleventh annual global celebration of open data is taking place on March 6, 2021. Open Data Day aligns with YouthMappers' goal of ensuring that the data, information, and results we create are freely available for the greater public good- particularly so that local populations can plan for the welfare, resilience, and vitality of their communities. This day recognizes and promotes open data and rallies groups globally to plan local events creating and using open data. This year the Open Knowledge Foundation awarded 61 mini-grants to support organizations for their Open Data Day events; four YouthMappers chapters were selected for the mini-grants!

Find event details from the chapter awarded grants below. Visit our calendar to see all of the virtual events catered to YouthMappers related to open mapping on and around Open Data Day. Also, view the Open Data Day events listing page to discover online and in-person events by country, theme, or region.

OpenStreetMap Introduction #OpenDataDay

PoliMappers, Politecnico di Milano

Milan, Italy


OpenStreetMap Introduction #OpenDataDay is the first event of the course Humanitarian Collaborative Mapping, organized by PoliMappers and coordinated by PoliMappers Faculty Advisor Prof. Maria Antonia Brovelli, in collaboration with the Politecnico di Milano and other numerous organizations active in the field of open mapping.


In a series of meetings from March to May, participants will be introduced to OpenStreetMap (OSM) and to some examples of how the database is used. Moreover, they will learn how to manage the most popular and innovative tools through mapping sessions.


The event on March 5th is held on the occasion of Open Data Day 2021 (March 6th), an annual celebration of open data all over the world. It is an opportunity to show the benefits of open data and encourage the adoption of open data policies in government, business and civil society.

Flyer promoting PoliMapper's Event Collaborative and Humanitarian Mapping OpenStreetMap Introduction on 5th March 2021 4-7pm CET.

The first part of the event will aim to introduce participants to OSM by explaining the project and the milestones reached so far, as well as the basic concepts of mapping.

In the second part of the event, an example of how OSM is now fundamental in the humanitarian world will be illustrated. This is the case of the World Food Program (WFP), which operates in many countries and uses the OSM database to constantly update its mapping resources and ensure optimal support to field missions. Participants will then try their hand at mapping buildings using the TeachOSM Tasking Manager and iD editor in the area around Tartus, Syria, where the WFP operates.


The course and the March 5th event is open and freely-accessible for interested people from outside Politecnico di Milano. Register here to receive reminders and info before each event.

Mapeo Comunitario Evento Online- Dia De Datos Abiertos Mapatona

YouthMappers UFBA, Universidade Federal da Bahia

Salvador, Brazil

On March 6th at 16:30 UTC for Open Data Day YouthMappers UFBA will host a mapathon in support of fighting epidemics in precarious areas of Salvador, Brazil - Subúrbio I. Brazil has a primary health care network in the Unified Health System (SUS) composed of community agents and family health professionals who work together in the territory with the most vulnerable population. However, this performance occurs with little (or no) knowledge organized in maps. YouthMappers UFBA supports training activities for these professionals and intends to count on the OSM community to map, at this moment, one of the precarious areas of the city that has been suffering from COVID-19 and in which one of these groups of health professionals work.


Community health workers and family health professionals play a fundamental role for these people, as they are the ones who visit the territory, the homes, recognizing the problems at their origin. To do their job, they often make schematic maps on paper and do not use existing maps. In OpenStreetMap, most of these more precarious areas still do not have their buildings mapped, and this is a layer that can help a lot in the work of these agents. That is why YouthMappers UFBA has been supporting the GeoCombate COVID-19 BA Group and seeking to map the most precarious areas of the City of Salvador.

Combatiendo epidemias en zonas precarias de Salvador, Brasil - Subúrbio I

Brasil tiene una red de atención primaria de salud en el Sistema Único de Salud (SUS) compuesta por agentes comunitarios y profesionales de la salud de la familia que trabajan en el territorio junto con la población más vulnerable. Sin embargo, este desempeño ocurre con poco (o ningún) conocimiento organizado en mapas. Youth Mappers UFBA apoya actividades de formación para estos profesionales y pretende contar con la comunidad OSM para mapear, en este momento, una de las zonas precarias de la ciudad que viene sufriendo con la COVID-19 y en la que uno de estos grupos de profesionales de la salud trabaja.
