Who we are

PoliMappers is a volunteer students’ association founded in December 2016, based at Politecnico di Milano in Milano, Lombardia, Italy. The mission of the group is to train and motivate the next generation of volunteer mappers and to do mapping using free and open source software within the university as well as primary and secondary schools.

PoliMappers is the first European chapter of the International Association YouthMappers, founded in 2014 in the United States of America with the support of the United States Agency for International Development (USAID) to cultivate a new generation of leaders in the field of open geospatial data and technologies, with the purpose of creating through them resilient communities of the future.

YouthMappers is a global network that currently includes some 145 chapters in 41 countries. In accordance with the terms of participation of YouthMappers, the association's activities include at least two mapping activities per year: mapping the local area and participating in a YouthMappers network promoted campaign.
